Q: I have tiny brown ants everywhere: deck, garage, stoop, etc. I’ve used bait products plus I can spray an area and it may kill some but within an hour they are back.

A: You might not be waiting long enough. Baits are by far the best way to control ants in a home. But it takes a week or so to notice the decline in ant numbers. I do not recommend surface sprays since they do not kill the colony. I have more ant information, plus a boric acid bait you can make yourself, at bit.ly/antcontrol.
