The Terro that I have is from WalMart and I think most grocery stores sell it. It isn't doing anything for this batch of ants that I have. In fact, I think it's an aphrodesiac for this variety. When you spray the Ortho product, how much do you use? Is it hard on wood surfaces such as your baseboards.
My mom used to swear by Terro but it must not be the same as the product she used. Frankly, I don't care if those little creatures do explode. I've heard of using corn meal for them but these are so little that I wonder if they could carry that. When they are marching on my countertops and even across my plate on the table, they need to be gone whatever the means. Frustration!!!!
