im so close to just burning all my chicken houses...im so stressed! been fighting red mites for over a month, and just when i think ive got them all, another house breaks out in an infestation (( i empty out all the houses, take out all perches, brush off all loose dust...spray down with bleach water scrub and rinse, let them air dry then dust with mite powder, i have smeared all perches with vaseline then replaced and sealed around the edges so no cracks for the mites to get in. ive also sprayed with an aerosol type cannister that is supposed to be for blood mites in pigeons...i could geet this in all the small cracks and crannies. but within a week theres mites again, not many but they're their. if i dont intervene its a full blown invasion within a week. i cant keep taking the houses down and cleaning them out like this, its a days work on each house (and theres 7 houses out there! my chickens refuse to go in them anymore and all sleep along the fence posts which concerns me as they're open to predators at night. is there any sure fire way of getting rid of red blood mites from in the houses??? or should i just torch them all and buy new?? but then no doubt within a few weeks the new houses will be infected? what is causing the reinfection? the chickens have all been treated for mites, and these ones dont actually live on the chickens do they? but im guessing they are hitching rides from house to house? argh!!!!!!!!!!
