Treatment Tips

Carpenter Ant, Termite* and Carpenter Bee Control:

Apply TERRO® Carpenter Ant & Termite Killer to voids or channels in the damaged wood of structures; cracks and crevices between wooden portions of a structure or between wood and the foundation; and in locations vulnerable to attack, such as crawl spaces.

*For termite treatment, the purpose is to kill workers or winged forms which may be present in the treated areas at the time of application. TERRO® Carpenter Ant & Termite Killer is not recommended as the sole protection against termites. For active infestations, get a professional inspection.

Ant Control:

Spray TERRO® Carpenter Ant & Termite Killer freely around ant trails and hills. Use around nests hidden under steps, brickwork, concrete, etc. Break apart accessible nests and apply this deltamethrin spray freely on and around debris.

    Not as good as the previous aerosol spray By Mike

    This spray type bottle is not as effective as the old carpenter ant / termite product in the aerosol can with the extension tube. Hopefully Terro will bring back this product. It was better in that it was possible to push the tube in crevices where these critters reside. Thanks, Mike

    Terro products work. I have fired my Pest Control company years ago. Do it yourself and do it right. The only thing Terro needs is yard signs to promote their products.

    Amazon Review By Mary E
    It says on the bottle that it "kills on contact". I shower the carpenter ants with this and they don't even slow down. Maybe they die later.
    Ant spray for regular ants eventually kills them so I will stay with that.

    Amazon Review By Ron B.
    THE terminator of ants, wasp nests, etc. / good product- leaves toxic odors after apraying. But any chalk, few lines of chalk about ant lines, or draw a circle around where they are feeding, this a low toxic deal! CHINESE ant chalk best.

    This is an excellent product, it's easy to use and best of all it works really well. The spray kills the ants soon after you spray them and has good results.Also the Terro dust product used with the spray does the complete job.

    Kills all the ants in the bathroom! I have no pets in the house, but this does seem like it would be extremely bad for your pet... It doesn't smell but it does kill the ants instantly and they avoid it like the plague!

    Amazon Review By Patricia
    This product really works. We were experiencing carpenter ants as a result of untended leaks in my condo. Ants got inside, but I found that if I sprayed this on the rug where they came in or where they were able to walk to, the ants didn't live to walk more than several feet. It was amazing. For a week or two I checked the area once or twice a day and disposed of the ants. But the end of 2 weeks there were no more ants coming in and we did have the balcony with the wet wood repaired. There was no harm done to my rug, thankfully, because I would not have used it if there was. Great product.

    Q.Is this safe for pets when this dries in doorways and cracks they my walk over or by?

    Children and pets can re-enter the treated area after the spray has dried. Please keep in mind that this product is designed for crack and crevice use and not intended for broad scale application.

    Q.I directly sprayed this on soil where I planted my vegetables. My vegetables are still growing, and bearing fruits right now. Is it safe to eat those vegetables? 

    This product is intended for cracks and crevices only when used outdoors. We do not recommend allowing it to come in contact with food or food crops.

    Q.I have Carpenter ants . Your liquid ant bait traps appear to be too small for these large ants to easily crawl into and out of! What is your recommendation for liquid ant bait for carpenter ants ? Thank you; john

    Our liquid ant bait is not recommended for carpenter ants, as their diet does not typically include sweeter foods. Instead, we suggest using a contact killing spray, or our outdoor granular bait. Please feel free to contact our Consumer Relations Team at 800-800-1819 x 458 for assistance in determining the best product for your needs.
