I have a customer with American roaches in her shed. She's concerned if we treat the shed and kill the roaches the chickens next to the shed may get contaminated or hurt if they eat the dead roaches.
I really believe this is not a concern. The amount of actual insecticide active ingredient that is needed to kill a cockroach would be FAR too low to be harmful to the large chickens. However, it still would be a very good idea for you to ensure that dead cockroaches lying around are removed as soon as possible just to alleviate her fear. Frankly, roaches are pretty filthy animals, and the chickens probably stand a bigger risk of consuming some nasty bacteria and being made ill than they do any reaction to minute traces of insecticide. Poultry houses also routinely treat chickens directly with insecticides in an effort to kill the various bed bugs, lice, and mites that are common on these birds, so many insecticides can be used on and around the birds without harm to them.
