My tenant reported that ants have been digging dirt up between the cracks between house and sidewalk.

However, this seems to be quite a lot of dirt. Could it possible be termites causing this?



  • IDK but that's certainly quite a lot of dirt. But I'd assume w/e kills termites would kill ants and vice versa. And I don't see what a termite would find interesting below grade and next to a stone (?) foundation, and a real brick wall (?) that's not a facade over framing... unless you live in Australia (location ?)

    Ants, IMO. Termites don't like light, that's why they build mud tunnels. The ants are building a nest somewhere behind/under the brick. And that's probably a brick facade, with an airspace between the back of the brick and the framing/insulating material. My house is built that way.

    While you're deciding on a long term solution, you could start by spraying bug killer down the gaps between concrete and brick as a short-term fix.

    I would go with ants and get an exterminator in there right away that is a huge amount of material, I know ants will take the dead out with the debris that’s how they identified the type on houses I have had treated. I know termites do dig but I haven’t seen them bring material out like ants.

I agree with Steve. Ants for sure, maybe pavement ants. You can find several pesticides at DO MY OWN PEST CONTROL. I worked in pest control for 17 years. A Termiticide / Pesticide called Termidor SC will get rid of them for sure. Kinda pricey but it's a concentrate.

You'll probably pay more for a pest control company to do it. Do it yourself. One Ounce per Gallon of water mix should do it. Just follow the label instructions on the bottle.

  • Woody, I have a friend that used a special “licensed only” ant killer in the Pacific Northwest. It lasted ~10 years and killed all ants in ground and on wood. Do you know the name it really worked and may not be legal any longer as that was a few years back. I had spent a lot in that area trying to kill carpenter ants and that was the only thing that worked 100% on multiple houses I remodeled and owned. My friend retired and moved and I can’t find him to ask.
