Why won't house ants go away no matter what I spray?
Store-bought sprays like permethrin and common baits fail because they only kill surface ants while the underlying colony keeps reproducing and sending out new waves from hidden entry points. This endless cycle leaves homes overrun and makes it nearly impossible to clear the infestation without harming local pets or wildlife outside.
