Been in Central Texas and South Texas, ants are terrible.
The only product that works to kill them and deter them is Bifenthrin.
It is safe when dry around cattle, so it is safe to kids and pets just keep them away while it is wet.
I have only had to spray inside my home once in five years.
But if you already have ants in the house, you will need a few sprays in the house.
Then you need to spray the entire foundation of the house and ground nearby about once a month.
BIfenthrin is order online, I haven't seen it locally. It is a cream white product, you pour about 1 ounce into a 1 gallon spray bottle and spray the whole yard as well, including any active ant mounds.
It controlls mosquitoes also, and other pests (spiders, etc).
I told my neighbor about it when he had a terrible ant problem, his wife baked me cookies a couple weeks later and said thanks so much we have zero ants.
Most pest control companies use this chemical FYI.
Nothing at Home Depot or Lowes will compare!
