Ant Problem- help
We moved into a house in northern suburbs of Indianapolis and have been dealing with ants that seem completely localized to the front of the house. Most of the activity is around the front dining room baseboards and front windowsills. Outside we have a brick front patio and I am starting to wonder if there is a colony underneath it or around the foundation.
So far I have tried:
• TERRO indoor bait stations for about 3 weeks
• TERRO outdoor bait stations
• TERRO granules around the perimeter of the house
• Outdoor bait stakes around the front landscaping/window area
• Pressure washing the front patio and cleaning out dirt, leaves, debris, and the cracks between the pavers
It definitely helped outside. At one point there were hundreds of ants on the patio and now there are only a few. The problem is I am still seeing around 5 to 10 ants a day inside near the same dining room baseboard area.
I also have dogs, so putting bait directly where they are coming in has been difficult. I have tried placing bait near the baseboards at night when the dogs are put up.
Does this sound like pavement ants under the patio/pavers? Would you move to Advion next, a perimeter spray, sealing gaps, or just call an exterminator at this point?
I have never had an ant issue like this before and I feel like I have thrown everything at it already.
TLDR: Localized ant problem at the front of my house only (front dining room/baseboards/windows). Tried TERRO indoor and outdoor bait, granules, stakes, and pressure washed the brick patio. Outside improved a lot, but still seeing 5–10 ants a day inside. Wondering if they are nesting under the patio and what the next step should be.
