Pesticides

External parasites on poultry are a common problem in small flocks of birds. They often come in contact with the parasites or their eggs while foraging for food. The problems are less frequently encountered in commercial poultry flocks but treatments may also need implementing in these flocks. Several pesticides provide excellent protection against parasites. The product used and the method of administration is dependent on the parasite and type of housing conditions being used. A description of the most commonly encountered parasites can be found in the parasite section of Diseases of Poultry.

Listed below are several chemicals that have been approved for treating various poultry pests. Regardless of the chemical used in the poultry house, follow all precautions listed on the label to prevent the possibility of health risks to the poultry or humans.

Permethrin
5.7% EC Spray -- Dilute 7 tsp/gal or 1 qt/25 gal for .05% solution
-- Dilute 4 1/2 Tbs per gallon for .1% solution

10% EC Spray -- Dilute 4 tsp/gal or 1 qt/50 gal for .05% solution

25% WP -- 1.5 tsp/gal or 1 pt/30 gal for .05% solution
-- 1 Tbs/gal or 1 pt/15 gal for .1% solution

The .1% solution is applied to ceilings, walls, and suspended objects using a pressurized or power sprayer. This residual spray may remain effective for several weeks unless removed by washing or rain.

The .05% solution can be applied directly to the birds at the rate of 1 gallon per 75 adult chickens. The solution applied to the birds is effective for mites only. Pay particular attention to the vent area when spraying to insure complete spray penetration and coverage.

.25% Dust -- Apply with shaker can at rate of 1 lb/100 birds. Dust to cover vent area. Recommended for treatment of mites only.

 

Carbaryl (Sevin)
50% WP -- Dilute 7 oz/5 gal for .5% solution.

Spray the vent and fluff areas from beneath the bird. Provide mechanical agitation or stir mixture frequently. For litter operations, an evenly sprayed application can be made to the litter surface. Avoid contamination of feed and water. Treatment of infested birds only may be preferable to treating all birds in a flock. Northern Fowl Mites are tolerant to carbaryl in some poultry production areas.

Do not repeat treatment more often than every four weeks. Do not apply within seven days of slaughter.

5% Dust -- Apply with shaker can at rate of 1 lb/100 birds or dust bath box at rate of 5 lb/100 birds.

STARKVILLE, Miss. -- Increasing buffalo gnat populations are more than a nuisance to central and south Mississippians; they cause measurable, sometimes fatal harm to chickens and livestock.

Swarms of these insects, also known as black flies, are killing backyard chickens and causing headaches for small-scale poultry producers in central and south Mississippi. At about 3 millimeters long, buffalo gnats breed in flowing water, so outbreaks tend to be in areas near rivers or streams.
