Expatgirl,you should also check the link I left in my last post it also gets rid of fire ants and tells you how to get the queen so she wont be around to lay more eggs.It also says that medicated body powder or talcum powder repels fire ants I dont know if that works or not.If you get a chance mayby you could put some down on the ground to see if it really works or not.We dont have chiggers,fire ants,roaches and seldom a flea or tick on this part of the ranch but in Texas they do Im curious about the fire ants as they are where I work in Texas.I love experimenting on bad insects with natural stuff to see what happens Food Grade Dimetaceuos(sp?)Earth works good as it slowly eats away their outer skeleton causing them to die it works on any hard shelled insects like roaches and scorpions it's not instant but in time they will die.
