See just one ant is not of a big deal. But if you see that you have many, dont use any chemicals, just spray vinegar in your entrance points and/or if you spot where the ants are coming from, then spary there as well.
Vinegar is safe and will keep ants away for good, so there is not much to worry about
Boric Acid powder is by far the best! It may not kill the ant right away but if (or when) it rturns to the nest/hive it will sterialize the coloney..
or cayanne pepper
It's getting warmer where I live and the insects are starting to come back out. I just noticed an ant crawling on a wall near my bed. I killed but I'm worriied there are more close by. I had a really bad ant infestation in my romm two years ago. It took a few weeks to get them all out. I had to sleep in my base.ent the while time. I have no desire to repeat that experience. How do I stop this before it gets out of hand?
