Haven't much trouble with flies but ANTS!!! We have those little "sugar" ants that are so small that they come right through the screens! I've tried every thing possible and probable and STILL can't keep the things off the sink, table, bathroom counter, you name it!! And unfortunatly fly swaters are not an option. They even climb up on top of my parrot cage and get into his treat bowl! Sprays are not an option either.(alergic cat)Anyone have a solution I might not have tried yet??
