Military Pesticide Exposures (DEET, Permethrin, Organophosphates)

What Military pesticides is

• DEET (N,N-Diethyl-meta-toluamide) — applied to skin and uniforms.
• Permethrin — pyrethroid pesticide impregnated in BDU and OCP uniforms.
• Organophosphates (malathion, chlorpyrifos) — area spraying around base camps.
• Carbamates and other pesticides used in pest-control operations.

Who was exposed

• Service members deployed to malaria-, tick-, or sandfly-endemic regions.
• Pest-control specialists and entomologists.
• Gulf War veterans (high-intensity combined exposure).
• Vietnam-era veterans (DDT, malathion, lindane).

Recognized conditions & VA framework

• Gulf War veterans: chronic multisymptom illness and undiagnosed illness under 38 CFR § 3.317.
• Direct claims: peripheral neuropathy, cognitive symptoms, GI symptoms, and skin conditions where exposure is documented.
• Specific organophosphate poisoning cases supported by hospital records.

Evidence to gather

• Service records showing deployment to a pesticide-treated environment.
• Pest-control specialist MOS or duty records.
• Treating-provider notes on chronic neurological, GI, or skin symptoms.
• Nexus opinion citing the specific pesticide exposure.

Claim path

1. Gulf War veterans: file under § 3.317 for chronic multisymptom illness — pesticide exposure is one of the contributing exposures recognized in the science.
2. Other veterans: file direct service connection with documentation of duty and a nexus opinion.
