I use the stevena ? The dust stuff that you mix with their bath dirt. I put it everywhere even in the house and when I woke up I seen a few lost one . And in the house after two days I swept it up and put it in the yard for the chickens .Does any one know how I can get rid of ants without killing chickens? They are crawling on my chickens if they have any dirt on them and if I have eggs hatching they swarm the egg as soon as it pips.
