Permethrin Spray Concentrate for Chicken Mites & Lice

Finding mites or lice in the flock is bad enough. Nobody needs pesticide math making the day worse.

Choose between Durvet® Permethrin 10% and Martin's® Permethrin 13.3% concentrates for label-directed control of poultry pests and treatment of applicable poultry housing and premises.

Both are concentrated permethrin insecticides, but they are not interchangeable formulas. Mixing rates and approved uses depend on the product you choose, the pest you're treating, and where you're applying it.

Choose Your Permethrin Concentrate

• Durvet® Permethrin 10% Concentrate, 8 oz: Contains 10% permethrin. Labeled for use on poultry and livestock as well as applicable livestock and poultry premises. Durvet lists poultry lice, fowl mites, darkling beetles, flies, ticks, and other labeled insects among its uses.
• Martin's® Permethrin 13.3% Concentrate, 8 oz: Contains 13.3% permethrin. A more concentrated formulation with its own label-specific dilution rates, pests, and approved application sites.

Whichever bottle you choose, use the directions printed on that exact product label. More concentrate is not better, and directions from one permethrin product should not be substituted for the other.

How to Use

Read the entire label before mixing or applying either concentrate.

Follow the product-specific directions for the target pest, animal or premises application, dilution rate, protective equipment, environmental precautions, and any restrictions concerning feed, water, animals, or treated areas.

Do not guess at dilution rates or use directions from the other variant simply because both products contain permethrin.

Permethrin is highly toxic to fish and other aquatic organisms, and pesticide labels include additional environmental and safety precautions that must be followed. California registration is currently active for both products, but pesticide registrations can change.

Basically, this is not the time for a splash of this and a glug of that.

Read the damn label.
