I just found out that I have fleas in my run, since I live in South Texas this is going to be a constant battle for good. I have researched for 2 days and found this product (Archer- pyriproxyfen) which is IGR (third generation). I contacted the seller and he recommended to spray all the chicken yard, run and coops with a diluted solution of 1 oz per gallon of water. I will have to reapply in 10 days and then subsequently in 6 months. Archer kills eggs, larvae and pupae of all insects that go thru this phases in their life cycles (including mites) but does not kill the adults, for that I am planning to use chicken dust (permethrin/pyrethrin) to dust my 9 hens and spray permathrin in the run and coops. I am still debating on the dilution since there are difference of opinions about it in BYC. I love my girls and I certainly do not want to harm them but on the other hand I wish I would not have to use pesticides on them however fleas are not good either for them and they can become a real problem so I want to attack them before they decimate my flock.
Any words of wisdom from experienced and non experienced flocksters?
