Ants! If this is Texas, you've got 'em. Well, they've moved indoors (got tired of being chased 'round the yard, I suppose). I purchased ant baits in little plastic squares and those pesky little bugs just detoured. Left the traps in place anyway. After a day, the ants must have decided it's just part of the landscape, because now they are entering and I hope, exiting with a mouthful of the bait.
You can use white vinegar mixed with water and spray it on the walls, counter tops, around baseboards, plug ins, anywhere you see them coming in. Just mix two parts white vinegar to one part water in a spray bottle. Do NOT wipe off, allow to air dry. Also it can be sprayed directly on the ants, too. Also if you keep all the trees, limbs, etc away from roof then they can't climb up the trees and onto the house. I got this hint from an exterminator years ago and it works. I do NOT buy those "ant traps" because this is natural and frugal which is also much safer for the environment. I also live in Texas and have used this method for years and have NO ants in my home ever. Good luck, hope this helps you too.
