Insect-borne illnesses pose serious health threats to agricultural workers across the globe.
From mosquito-transmitted viruses like West Nile and Zika to tick-borne diseases like Lyme, farm workers face high exposure due to the nature of outdoor work environments. Protecting these essential workers is not just a health matter—it’s a critical workplace safety priority.
In this article, we’ll explore key strategies, gear, and preventive practices to combat insect-borne illnesses in farming, ensuring worker safety through each season.

Why Agricultural Workers Are at Risk of Insect-Borne Illnesses
Agriculture jobs often require long hours in rural or semi-rural environments—prime habitats for insects. High humidity, standing water from irrigation, dense vegetation, and livestock presence all attract biting insects. These conditions heighten the risk of workers contracting diseases such as:
- Lyme disease (from ticks)
- West Nile virus (from mosquitoes)
- Zika virus
- Dengue fever
- Chikungunya
- Rocky Mountain spotted fever
According to the Centers for Disease Control and Prevention (CDC), outdoor workers are one of the most vulnerable groups for insect-borne illnesses.
Key Strategies for Preventing Insect-Borne Illnesses
Use of Insect Repellents Effectively
Applying insect repellent is a frontline defense. Products containing DEET (20–30%), Picaridin, or Oil of Lemon Eucalyptus are recommended. Train workers to:
- Apply repellents before entering fields.
- Reapply after sweating or heavy rain.
- Avoid contact with eyes, wounds, or irritated skin.
Workers should always wash off repellent before eating or smoking to prevent ingestion.

Wear the Right Protective Clothing
Insect-resistant clothing adds a barrier between skin and biting insects. Encourage workers to:
- Wear light-colored long-sleeved shirts and long pants (insects are more attracted to dark colors).
- Tuck pants into socks or boots.
- Use permethrin-treated clothing for extra protection.
- Consider wearing head nets during heavy insect seasons.

Eliminate Breeding Grounds at the Worksite
Mosquitoes breed in standing water and damp conditions, which are common around agricultural areas. Implement site controls like:
- Draining or covering stagnant water (e.g., buckets, barrels, troughs).
- Keeping animal pens clean and dry.
- Managing irrigation drainage to prevent pooling.
- Cutting back tall grass where ticks may hide.
Regular inspections by OHSE professionals should be part of your pest control plan.
Training and Awareness
An effective insect protection program includes training on:
- How to identify insect bite symptoms.
- How to conduct tick checks after fieldwork.
- First-aid response for allergic reactions.
- Reporting suspected illnesses immediately.
Seasonal toolbox talks and posters around farms can reinforce daily awareness.
📌 Consider using posters with phrases like:
“Don’t Let Bugs Bite Back – Use Your Repellent!”
“Ticks Travel Silently. Check Daily!”
Using Integrated Pest Management (IPM) on the Farm
Integrated Pest Management (IPM) combines biological, cultural, and chemical methods for effective long-term insect control:
- Biological: Introduce natural predators or microbial pesticides.
- Cultural: Adjust planting times and crop placement to avoid insect peak periods.
- Mechanical: Use row covers, tillage, and weed control to disrupt insect life cycles.
- Chemical: Apply targeted pesticides, following safety protocols and OHSA guidelines.
IPM reduces overreliance on chemical sprays and supports sustainability in agricultural operations.
Legal and Regulatory Requirements
Insect-borne illnesses fall under workplace health risks, so compliance is essential. Under most Occupational Health and Safety Acts, employers have a duty to:
- Provide hazard communication.
- Supply PPE and training.
- Implement controls for known health risks.
- Maintain health records and incident reports.
In Canada, insect safety measures may also relate to Seasonal Agricultural Worker Program (SAWP) standards. International farms should check with local labor safety laws and agricultural ministry guidelines.
Emergency Response and Bite Management
Despite best efforts, bites may still occur. Every agricultural site should have:
- First aid kits stocked with antihistamines, antiseptics, and tweezers.
- Emergency protocols for severe allergic reactions or suspected infections.
- Documentation procedures for bites and illnesses, to support future prevention and claims.
Educate supervisors on signs of anaphylaxis or illness progression and ensure emergency numbers are clearly posted near work zones.
Insect Safety and Worker Well-Being Go Hand in Hand
When workers feel protected from painful or dangerous bites, they can focus more effectively on their tasks.
Insect prevention also helps maintain attendance, avoid costly sick days, and protect vulnerable workers such as migrant laborers, older workers, or those with compromised immunity.
Farmers and managers must also lead by example—by wearing PPE and showing commitment to safe work practices.
Conclusion: Bite Back with a Proactive OHSE Strategy
Preventing insect-borne illnesses in agricultural workplaces is an essential part of occupational health and safety.
By taking proactive steps—ranging from environmental controls and PPE to training and emergency preparedness—farm employers can significantly reduce the risk of illness and discomfort among their workers.
