Intervention Techniques - WEEVILS

Physical

• temperature extreme
• modified atmospheres
• diatomaceous earth (may be less effective for adult beetles with hard exoskeleton)
• Pheromone traps
• mechanical forces

Chemical

• Surface treatments. (powders, paints, surface sprays) Insecticides (pyrethroids, organophosphates, carbamates, etc.) - long residual effects
• Space treatment. (aerosols, fogs, fine mists) Insecticides (pyrethroids, organophosphates, carbametes, etc) - quick knockdown
• Fumigation. (lethal gasses) Highly poisonous gaseous substances (Hydrogen Phosphide, Hydrogen Cyanide, Methyl Bromide, Ethylene Oxide)

Biological

• B.t. - Bacillus thuringiensis
