To control chicken mites, you will also need to apply pesticide sprays to litter, bedding, and building structures in order to kill the mites that are hiding in the sur- rounding environment. When treating building structures, it is best to use a liquid spray so the pesticide will be able to penetrate small cracks and crevices. For poultry kept on litter, you can use a dusting box (24 36 4 in [61 91 10 cm]) contain- ing pesticidal dust for periodic treatment of birds, so long as you do not exceed one treatment every 4 weeks. Pesticidal resin strips placed into poultry cages or nest boxes can provide continuous control of lice and mites. These strips should be placed near food and water sources or roosting sites so the birds will have daily exposure to the strips. Use pesticidal resin strips only during months when you would normally expect louse and mite populations to be high; that way you can delay the development of pesticide resistance and preserve the usefulness of these products. When applying pes- ticides, always carefully follow the label directions provided with the product and any withdrawal periods required before slaughter of the treated animals.
