BASF Termidor Foam 20 oz - Termiticide Insecticide for Termites, Ants & Wood Destroying Pests & Insects

We purchased this product to spray in our walls to kill a suspected carpenter ant nest or a part of one that was left behind when we removed a nest from our outside staircase. We had already torn out a ceiling and removed another next and did not want to open an entire interior wall in our house where the last batch of ants that seemed to mostly be nesting in the staircase are. We made two holes at the access point where we know ants were crawling in through a bit of wood that had gotten water damaged. It appeared they all were living under stair boards but we had some coming inside suddenly once we killed that nest and sealed up access to outside. We probably sealed up the outside access too soon. Since I can’t see in the wall I honestly don’t know if this worked but we did see an ant here and there after spraying, even some winged (smaller ones) . They were all very close to dead and died shortly after I saw them. We also dusted in cracks in the area and in the holes after we sprayed this so again, I’m not 100% but it seems like a good product. We may use it in a couple other areas in the wall if we see any other ants in the next week. To note: at the beginning of all this we used an exterminator who honestly was clueless. The one good thing is his baiting and perimeter spray slowed the ants down so I was able to watch them over the weeks and find the nests. I spent days watching them. The exterminator came three times and I had more of a clue about carpenter ants then him. I suggest trying this if you’re at your wits end and feel very strong you know where the nest is. The price is great compared to an exterminator fee. I will say though, if you can remove the nest, it feels good to just rip it out of the wall but that’s not always practical in every case and it is seriously disturbing!

What’s good about this stuff? Is they take it back to the ass and they kill everybody else it’s good stuff.

This summer I had a carpenter ant nest in the foam a cathedral ceiling that was insulated with spray foam. I drilled small holes at the top and bottom of each rafter bay and sprayed this stuff in there between the foam and the wood ceiling. Also did some areas in walls nearby where they were traveling. I put out bait a week before this treatment. This treatment was the KO punch. cleaned up dead and dying ants for several days, and after about a week no signs of ants remain. Its been a few months now and no ants have been seen since.

Had a problem with termites and carpenter ants and this product was the strongest and fastest product that actually worked after using it. The price was a little bit high but it worked so well I soon let that go. Definitely worth it.

Works great and killed the borers. Price and quality good. Easy to use.

Super working good

Not sure how effective it is yet, but it arrived on time and was easy to use/apply! Thanks!

Unfortunately this did not seem to work for the ants I'm trying to get rid of. It's the same chemical as other applications so can't say it's the foam bottles deficiency. We may have carpenter, maybe pavement ants, not sure. The bottle and foam... Mixed feelings it mostly works but can leak if not held properly and must shake repeatedly to get it foamy not drippy.
