If a desert locust swarm is approaching a farm or grazing area in Ethiopia, report the sighting promptly to the kebele or woreda agricultural extension office and follow instructions from authorised Ministry of Agriculture and regional plant-protection teams. Give the approximate location, time, direction of movement and whether you have seen flying adults or clusters of wingless young locusts. Do not attempt improvised pesticide spraying, enter an aircraft’s treatment area or handle unidentified chemical products without appropriate training. FAO says locust control operations should be carried out by trained and properly equipped teams, not by untrained communities or individual farmers.
If officials announce pesticide treatment nearby, keep children, livestock and other people away from the marked treatment zone for the period specified by the responsible team. Follow the official instructions about grazing, water and harvest. Do not eat locusts from a treated area, food that has been contaminated by spraying, or animals that may have consumed treated locusts without approved safety advice. If anyone develops possible pesticide poisoning symptoms, stop exposure, move to clean air if safe and obtain urgent professional medical care with information about the product, if available.
Quick answer: A desert locust event can progress from favourable breeding conditions to concentrations of young hoppers, mobile bands and flying swarms, followed by rapid feeding on crops or pasture, organised surveillance and control, and weeks or months of livelihood consequences. This is a food-security and agricultural disaster, not normally a flood-style emergency that everyone must evacuate from. Danger arises from crop loss, reduced animal forage, lost household income and unsafe attempts to control insects with chemicals. The exact situation changes with rainfall, wind, ecology and official control operations.
First 10 actions for farmers, pastoralists and households
- Check the newest FAO Locust Watch bulletin and information from Ethiopia’s Ministry of Agriculture. A historic outbreak headline is not a current local warning.
- Report a suspected swarm or hopper band to kebele/woreda agricultural or plant-protection officers with the location and time of observation.
- Do not enter areas marked for pesticide spraying or approach aircraft and field-control teams to watch.
- Move livestock away from treatment zones when officials direct it and observe re-entry and grazing restrictions.
- Protect stored food, drinking-water containers and animal feed from chemical contamination, following local safety directions.
- Do not mix or apply unknown agricultural chemicals yourself. Leave official locust-control operations to trained and equipped specialists.
- Document crop or pasture damage safely, noting field location and the date for verified extension or relief assessments.
- Ask agricultural authorities about approved monitoring and recovery support, not guaranteed compensation from strangers.
- Prioritise household food and safe water as crop losses begin to threaten meals, and seek health or nutrition help when needed.
- Keep monitoring after a swarm moves away. New breeding, wingless hoppers or later swarms may change local conditions.
Stage 1 — Rainfall, soil and vegetation: why locust numbers can rise
The desert locust (*Schistocerca gregaria*) is a species capable of dramatic changes in behaviour and movement. When populations remain sparse, individuals may be widely dispersed and difficult to notice. Under favourable conditions — including suitable rainfall, moist sandy soil and green vegetation — breeding can increase numbers.
Several generations of successful breeding can build an increasingly large population. Crowding may lead to a behavioural and physical transition toward gregarious individuals that form groups, hopper bands and swarms. The conditions depend on actual weather, habitat and population status; one rainy week does not guarantee a plague.
Ethiopia’s arid and semi-arid regions connect ecologically with wider desert locust movement in the Horn of Africa and neighbouring regions. Some agricultural and pastoral communities may be exposed even if their own area was not the site where a swarm first bred.
A Ministry of Agriculture environmental and social management document describes different seasonal breeding areas in parts of Ethiopia, including areas of Afar, Somali and other regions. Those are planning descriptions from a dated programme, not a guarantee of present infestation in a particular woreda.
Stage 2 — Early-warning information: what a forecast actually means
The FAO Desert Locust Information Service analyses field surveys, rainfall, vegetation conditions and locust reports, then issues regular updates and outlooks. These forecasts support national survey and control operations. They are not street-level instructions telling an individual farmer to spray a chemical tomorrow.
Read the current bulletin’s issue date, country, affected regions and forecast period. FAO’s bulletin archive includes reports that may remain online long after the situation changes. A bulletin labelled September 2026 is important historical context, but it does not establish which fields are threatened in November or on the day this article is read.
The Ethiopian Ministry of Agriculture and its regional and local agricultural offices translate monitoring and assistance into operational decisions. Local field teams may know whether hoppers are present, whether control is planned and whether a specific village lies close to a treatment area.
A useful farmer question is “Is this confirmed in our area, and who should I notify if I see more insects?” That is more actionable than relying on a photograph of a swarm from another country.
Stage 3 — First sightings: distinguishing hoppers from flying adults
Desert locusts undergo stages of development. Young wingless insects, often called hoppers, can form marching bands. Later, winged adults may gather into flying swarms. These stages matter because surveyors and control teams may choose different methods and locations for monitoring and treatment.
A local observer might see groups moving through low vegetation, adults resting in crops or a large cloud of insects travelling in the air. Do not assume every grasshopper is a desert locust. Other insects may look similar, and a farmer might misidentify the species without expert assistance.
Report what you actually observed rather than what you think experts wish to hear. Useful details include the field or grazing location, landmark or GPS point, date, time, approximate area, visible stage and any damage. Photographs taken from a safe distance may assist identification, but do not enter a restricted or unstable area just to improve an image.
A report should go through a known kebele, woreda, regional agriculture or trained survey route. An unverified social-media post may spread faster than it can be checked but is not a substitute for the official surveillance system.
Stage 4 — How the swarm moves: what farmers may see
Flying swarms can move long distances with winds and suitable atmospheric conditions. Their direction may change, and not every swarm lands on every farm along its path. The insects can feed on green leaves and crops, affecting vegetation that supports household food, market production or livestock grazing.
The experience may be dramatic: many insects visible in the air or landing over plants. Yet the most important questions are not how frightening the swarm looks but which crops or pastures have been affected, whether younger populations remain and what control response is planned.
Do not pursue a flying swarm by vehicle in an attempt to reach it before authorities. Rural roads, private land, spraying operations and unsafe pesticide handling can create additional dangers. Calm, accurate reporting is more useful.
Households do not normally need to evacuate a sound home simply because locusts are flying past. However, follow any specific safety or movement instruction related to control operations or other hazards.
Stage 5 — Crop and pasture damage: the effects can be uneven
A swarm can feed heavily where it lands, affecting leafy crops, grain fields, pasture and other vegetation depending on season and conditions. The damage can be intense in one location and much lower nearby. The fact that a neighbour has lost a crop does not prove every field in a woreda has the same outcome.
For smallholders, damage may threaten household food and money expected from a harvest. For pastoralists, loss of grazing may add to existing pressure from dry weather and limited water. Food prices can rise in affected markets if production and distribution are disrupted, although changes depend on many economic factors.
Record losses through approved agricultural extension assessments. Keep dates, field locations, crop types, photos and relevant documents where safe and practical. Do not exaggerate, and do not assume that a photograph automatically guarantees compensation.
If food supply is deteriorating, consult local health services and verified community assistance programmes early. Children, pregnant people and households already facing food insecurity may require additional support.
Stage 6 — Survey teams and eLocust tools: why reporting matters
Official survey teams inspect potential breeding areas, record locust stages, monitor the extent of the infestation and transmit information to national centres. In May 2026, FAO announced an upgraded eLocust4 tool to support satellite-linked field reporting in 18 affected countries, including Ethiopia.
This matters because remote grazing areas may have poor mobile reception. Satellite reporting helps authorised teams transmit observations without waiting for ordinary network coverage. However, it does not mean every farmer has access to an eLocust device or that every report produces immediate treatment.
Use local agricultural contacts to provide the information that field teams need. Avoid entering protected land, unfamiliar border routes or unsafe terrain to collect data without official authorisation.
A survey is not itself spraying. Reports may lead to continued observation, a decision to treat a localised area, or a revised risk assessment. The type and timing of control depend on the population, environment and available trained personnel.
Stage 7 — Control operations: do not turn pest control into a poisoning emergency
FAO’s desert locust FAQ explicitly states that survey and control are primarily the responsibility of national ministries of agriculture, supported by trained teams and relevant regional organisations. Control may involve specialist ground or aerial methods and approved pesticides or biopesticides.
Untrained people should not apply pesticide in an improvised attempt to stop a swarm. Mixing concentrated chemicals, using products intended for another purpose, applying excessive quantities or spraying without protective equipment can harm humans, animals, crops and water supplies.
When a control team announces an operation, follow its instructions about distance, restricted zones, moving livestock, protecting household water and how long an area must remain closed. The appropriate re-entry interval depends on the product, its application and national rules; there is no single safe number of hours for every treatment.
Do not allow children to play in a treatment area. Do not collect freshly sprayed locusts for food. Do not graze animals on a treated field until the authorised team says access is permitted. Do not wash pesticide containers in streams or reuse them for drinking water.
The safest method for a community is to work with recognised extension and plant-protection services rather than attempt an amateur chemical campaign.
Stage 8 — During spraying: protecting people, animals and water
An official treatment operation may involve aircraft, vehicles or teams on foot. Residents should know which fields are included, whether houses or livestock routes are nearby, and what precautions the authorities require.
- Before spraying: ask the official team about dates, boundaries, product restrictions and alternative livestock movement where necessary.
- During spraying: stay outside marked zones, keep children away, protect approved water and food storage, and follow instructions to remain indoors when advised.
- After spraying: observe the official waiting period before returning, harvesting, grazing, drawing water from affected sources or handling treated vegetation.
- If you suspect exposure: leave the area when safe, avoid touching contaminated materials unnecessarily and obtain medical guidance with the pesticide name or label if available.
- For livestock: seek veterinary assessment when animals have been exposed or show concerning symptoms rather than using unverified remedies.
FAO notes that teams are trained in protective clothing, correct application and reducing environmental contamination, and that treated areas have specified withholding periods. A community must not assume that because officials applied the pesticide, all restrictions instantly end when the aircraft leaves.
Stage 9 — Livestock and pasture: why pastoral households face a different problem
In pastoral communities, the loss of grazing may threaten animals even when no grain crop is present. A household may already be facing water scarcity or drought, making pasture loss particularly serious. Moving herds can increase labour demands and expose people to unfamiliar routes or conflict over scarce resources.
Ask local veterinary and livestock officers about available safe forage, water and movement options. Do not move herds through a marked pesticide-treatment area or feed them treated vegetation without official clearance. Some chemicals and environmental conditions require specific protective measures.
Fodder allocation and animal treatment should be based on species, age, physical condition and qualified local advice. A universal online feeding formula would be unsafe and misleading.
Record pasture impacts as well as crop damage through recognised assessments where available. Relief programmes sometimes focus on farmers, and pastoralists should make sure their needs are accurately communicated to the appropriate local office.
Stage 10 — Household food security and financial decisions
A locust invasion can become a disaster well after the insects leave the field. Households may have lost a season’s expected harvest, be unable to replace seed or need to buy food at a higher cost. Some may be tempted to sell vital assets or borrow under unfavourable terms.
Start by assessing how much safe food and income remain for the household and when the next harvest or payment is expected. Work with known agricultural and social-support services to identify available assistance. Do not rely on unsolicited messages promising guaranteed grants for a fee.
If children are losing weight, frequently ill or unable to eat sufficiently, contact licensed health workers for assessment. A crop problem and a medical nutrition problem need different expertise. Do not wait until the household’s difficulties become severe before asking whether support is available.
Community organisations may also help with information distribution and transport to authorised assistance sites. Protect personal data when registering; never reveal banking PINs or passwords to someone claiming to represent a relief agency.
Stage 11 — When the swarm moves away: the threat may not have ended
A flying swarm can leave one locality while another group arrives later. Eggs or hoppers may remain in breeding habitats even after large flying groups move on. Weather and vegetation conditions may allow renewed breeding.
Continue monitoring FAO and Ministry of Agriculture updates, especially where officials identify continuing surveillance. Do not stop reporting observations because the first control operation has finished.
At the same time, do not treat every later grasshopper sighting as proof of an imminent nationwide plague. Accurate species identification, density and field survey information matter. Unnecessary panic can encourage harmful pesticide use or unnecessary crop destruction.
If an area has been sprayed, continue respecting re-entry restrictions and report any suspected human or animal exposure to medical or veterinary professionals.
Stage 12 — Recovery: replanting, livelihoods and the next season
A damaged field may require resowing, different planting timing or other agronomic measures. The best decision depends on rainfall, soil conditions, season, available seed and the crop’s market and household value. Agricultural extension services can help determine whether replanting is feasible.
A family with livestock may need a longer period of safe forage and animal-health support, particularly after drought or other shocks. Rebuilding savings and stable markets can take far longer than clearing one swarm.
The Ethiopian Ministry of Agriculture reported in July 2026 that its Desert Locust Control Project had operated across many districts and reached farming and pastoral communities. This demonstrates an institutional response system, not a promise that a particular village currently qualifies for assistance.
A useful recovery plan preserves evidence of losses, identifies safe local inputs, monitors future breeding risk and avoids repeating unsafe chemical practices.
Why Ethiopia’s locust response depends on regional cooperation
Desert locusts move across national borders and ecological regions. Control in one Ethiopian woreda may be affected by populations and rainfall in neighbouring areas or countries. Local reporting, national coordination and international information all matter.
FAO’s Locust Watch helps combine monitoring from multiple countries. The Ministry of Agriculture is responsible for national operations, while regional and woreda teams make surveillance and extension work practical on the ground.
The importance of this system is that a swarm does not respect district borders. A region that has not yet observed major crop damage can still contribute useful early warning, provided its reports are accurate and verified.
Farmers should not have to identify cross-border flight paths themselves. Their most valuable contribution is timely, credible local information and compliance with safe control instructions.
A realistic scenario: a household sees hopper bands
A smallholder in eastern Ethiopia notices large groups of wingless locust-like insects moving through vegetation. Instead of spraying a mixture from an unlabelled container, the farmer contacts an agricultural extension officer and provides field coordinates and the observation date.
An authorised survey team assesses the insects and determines whether further surveillance or control is required. The family follows any announced treatment restrictions and keeps livestock away from marked areas. Later, if crop damage occurs, it documents the loss through the official assessment process. This is an illustrative scenario, not a current report of a swarm in any particular Ethiopian district.
A second scenario: a pastoral community near planned aerial control
A pastoral group learns that trained aircraft crews may treat an area containing locusts. The community asks local officials to identify the precise boundary and time of the operation, and where animals can safely graze instead.
Households keep children away from the marked treatment area, cover water and food as advised, and do not enter the site until the announced withholding period has ended. A person who reports symptoms after possible chemical exposure is referred for medical assessment, rather than given an improvised home treatment.
The example shows that pesticide exposure, not the insects themselves, can be the most immediate human safety concern during control operations.
Seven myths and mistakes to correct
- “Every grasshopper is a desert locust.” Proper identification matters.
- “One rainy season guarantees a locust plague.” Breeding and swarming require multiple environmental and population conditions.
- “The swarm must be sprayed by anyone who sees it.” Control requires trained and equipped teams and approved products.
- “More pesticide is always better.” Excess or incorrect use can harm people, animals and the environment.
- “Once spraying ends, livestock can return immediately.” Follow the product-specific official waiting period.
- “Eating sprayed locusts is harmless.” FAO warns against consuming treated locusts and related contaminated animals.
- “When the insects fly away, the household has recovered.” Crop and income losses may continue for months.
Community and farm preparedness checklist
- Save FAO Locust Watch and the official Ethiopian Ministry of Agriculture.
- Know the agricultural extension contact for the kebele, woreda and region.
- Learn to report the date, location, insect stage and observed damage clearly.
- Avoid using unregistered or unlabelled pesticides and never handle concentrated chemicals without training.
- Know who will inform your household of official treatment locations and exclusion periods.
- Protect drinking-water sources, food stores, children and animals during authorised control work.
- Keep records of crop and pasture conditions before and after an event.
- Ask agricultural and veterinary officers about safe planting, feed and livelihood recovery options.
- Seek health or nutrition care promptly if food shortages cause illness or serious dietary problems.
Frequently asked questions
Can desert locusts directly injure people like a poisonous insect?
Desert locusts are primarily an agricultural and food-security threat. The main human concerns are loss of food and income and possible exposure to pesticide during control operations, rather than a venomous bite or sting.
What should I do when I first see a large swarm?
Report its location, time and movement to the kebele/woreda agricultural service. Follow official advice; do not attempt improvised spraying.
Should I evacuate my home because locusts are flying overhead?
Usually no. Locusts are not normally an immediate life-threatening physical hazard that requires household evacuation. Follow any specific authority instruction connected to nearby control operations or another danger.
Can farmers spray ordinary household insecticide on a swarm?
Do not improvise. FAO advises that locust control should be conducted by properly trained, equipped teams with approved methods and precautions.
How long after spraying can animals return?
That depends on the product and the official re-entry and grazing restrictions. Follow the authorised control team’s instructions; no universal waiting time is safe to print.
Is there a guaranteed payment if a farm loses crops?
No. Assistance and eligibility depend on current programmes, location and documented losses. Verify any aid claim through legitimate agricultural or relief offices and never pay someone to guarantee a grant.
