Our hen house is completely infested. I have sprayed the house out with insecticide every three days for the last week but I keep finding new places where they are hiding - today I have found hundreds between the roof felt and the roof.
It is an old style wooden house - full of nooks and crannies, have I got any hope of clearing them now? Or should I give up - get rid of the house & get a new plastic one?
Do they live in the ground? If I bring in a new house will that get infested too? The hens are temporarily relocated into an old run, but I'm not very happy with it because it wasn't designed for so many hens (5) so I need to make some quick decisions really.
Any advice gratefully received!
