Ant Control on Simple Pest Control has a huge list of ant control techniques (even mentioning your boiling water idea, which I'd never heard of - I'll have to try that!). It includes a lot about behavior control, ie, keep them from wanting in your house to begin with, to keeping them out of the areas you don't want them in, etc. The Biological Control ...

Killing the ants is one thing, and the comments from others are good. However, you need to fix the root cause of the problem, which is hole that you can see daylight from. Spray foam will only deter them for a while. You should NEVER be able to see daylight through a wall from the inside of a home. I would take a good look outside and see how much of a ...

Some options to consider: ant poison (Terro a being a popular choice) fill in the crack (concrete crack filler) get a pet anteater (not sure how easy they are to house train) Once the ants are gone, you can then get perimeter ant poison for your big-box DIY retailer. It's a granule that you can spread around the perimeter of your house to help prevent ...

I am a huge fan of Amdro. I find it works most of the time in a day. Every now and then I get a mound that needs a second application. I find good results if I don't mess with the mound and I hit them in the morning. Having a pet I do spread some bait outside of his play area even when there are no mounds. I have even gone into my neighbors lot and ...

If the product you used mostly worked, you may want to try a second application to wipe out the rest of the colony. After doing some research there doesn't seem to be any tried and true solution to killing the ants (at least none I could find, I'm sure there are tricks exterminators use that they don't want to share), but most solutions seem to involve ...

You have to stop them at the source. Use baits that ants will gather and take back to their nest, or follow the trail back to the nest and Raid the entire trail + nest. I've also been known to put a pesticide in my lawn and flower beds once or twice a year to keep them from getting near the house. I try to make a 10' perimeter around the home.

Not sure about how effective they are specifically on ants -- but I do know one major drawback with these devices: they don't work around corners or behind objects. In other words, they are line of sight only. If the ants are behind cabinets, appliances, in the walls, etc, these devices won't work. My own approach to this issue has been to use pesticide ...

The gap is not unusual. You could put spray foam there, but it will only have a negligible affect. I've had ants come in through an electrical outlet before. Any tiny opening is sufficient for their single-file "column" to come marching through. Hurrah! Hurrah! The best thing to do is to apply a bait/poison like Amdro along the base of the exterior wall and ...

I would think you would go to an auto parts store and get a filler like Bondo . Bondo has a pretty high heat rating and is not flammable in your conditions. You will sand the areas, use mesh for bigger holes and apply. You can't put this stuff on paint - it won't stick well. And I would make sure the bonding area is rust free too. This should be about a ...

Ants, and particularly carpenter ants, in wooded areas with plentiful food will be ubiquitous. If your property is sufficiently wooded it's likely that there are multiple colonies. Carpenter ants are crafty, too. They are also hardier against poisons and pickier with baiting than other ants. When we had a problem with them I asked a few entomologists I know ...

My own (not) special blend of herbs and spices. Specifically, 1.5 cups warm-to-hot water (warm water mixes better) .5 cups sugar 1.5 tablespoons 20 Mule Team Borax Mix vigorusly. The method of delivery I used was soaking a cotton ball in the mixture and placing the cotton ball on juice bottle top or something similar, and placing this in (a) strategic ...

Though I'd second the Amdro I'm a big fan of the Ortho Orthene. It doesn't require watering in, and doesn't use much material at all. Though it can't be broadcast (so you can't do a whole yard) it'll usually wipe out a mound in a few hours.

This is why I would never hire someone who only does new construction. They don't take pride in their work, they only do enough so that the new homeowner doesn't complain. To really fix this problem permanently, you are really going to have to "dig" into the wall. Which is why the builder just put in some spray foam. Otherwise they would have had to spend ...

If the ants have a nest in the house, you will have to find the nest and destroy it. Then you will have to prevent them from getting back into the house and creating a new nest. If the ants are entering the house from the ground, you could spread Borax around the house. The ants will crawl through the borax on the way in and die. If the ants are coming ...
