TERRO T1901SR Ready to Use Indoor and Outdoor Carpenter Ant, Termite, and Carpenter Bee Killer Aerosole Spray - 2 Pack 32 Total Ounces

This was the only thing to consistently kill the carpenter ant invasion we had in our bathroom. Drilled a couple holes in the wall and filled the cavity with the vapor, sealed it back up and their numbers slowly dwindled down to nothing.

I don't know if carpenter ants these days have been bio-engineered, but they are fast, armor-plated little buggers and normal pest control measures, they just laugh at. This stuff works! It affects their nervous system and they either go belly up immediately or they run around in circles for a while, then go very still. Apparently does not kill pets, which is always a good thing.

It is effective for several months and then requires additional spray!

Fast acting with good results.

This stuff is really toxic according to the instructions.Use it as a last resort.I found it takes 3 or 4 days to kill wood borrers.A bit frustating when you have 20 or 30 drilling holes in your house.Also, application is difficult.You have to put the tube in the hole the bee made and give it a shot.The can needs to be held upright wich requires the tube to be bent up into thebee hole. This requires two hands with no more hands left to hang onto a ladder.Also, you need face protection because the foam can and does blow back in your face.Surface spraying does not seem to work as well or at all.With all that said, the stuff DOES work.It goes a long way if you are just giving a little shot in each hole.I would give it five stars if it were easier to apply and worked faster.

I just found my house been attacked by carpenter ants (the big black ants about 1cm long each), they came from different directions outside the yard. I used dozens of different insect control spray, vinegar, detergent for a month, it killed some on the spot but they kept coming back right the way. I found this one from the Amazon, sprayed the foundation around the whole house, the ants disappeared from outside of the house next morning and only found one or two per day for five days found inside the house, now almost a month and no more ants found inside or outside my house.The container will not work properly if you do not shake well before use and hold it straight up, the yellow color chemical foam spray for about 80 feet per container.This product not available at most of the local hardware stores. The price is a little cheaper from Amazon and I received it in couple days
