sorry if this is the wrong section - couldn't think of one that looked more appropriate. we have teeny tiny wandering ants throughout the house - a bit bigger than a large grain of pepper. They tend to just wander aimlessly across kitchen and bathroom counters. think they're called "crazy" ants. we had the house sprayed, but it didnt' really help because they seem to be moving through the walls, coming through electrical outlets, behind tiles, etc. if we manage to make them go away one place, they just pop out somewhere else. Does anyone have any advice on to get rid of them and KEEP them away? I've heard rubbing down surfaces with acid solutions? (vinegar, lemon juice etc) and soapy water; also with ground pepper? any other solutions that doesn't require major chemical treatments via an exterminator?
