Keep ants and other unwanted insects out of your house with TERRO® Ant Killer Plus. These fast-acting granules can be used as a perimeter treatment around the foundation of your house, as a general lawn treatment, or as a spot treatment directly on ant hills and fire ant mounds. The powerful formula kills listed insect pests on contact while also providing residual repellency.
Easy to Apply
To allow for ease of use, TERRO® Ant Killer Plus is packaged in a convenient, resealable shaker bag. Just open the top, grab the bottom of the bag, and start spreading the ant killer granules. There’s no chemical spreader or broadcaster needed!
How to Treat a Perimeter
Keep ants, cockroaches, fleas and other listed insects out of your house by applying a 3 to 10 foot band of granules along your foundation. Water lightly immediately following application. It is best to treat the foundation when insects first appear or when you notice lawn damage. For best results, remove leaf litter and cut back vegetation that touches the foundation.
How to Treat Ant Hills
To control ants (except fire ants), apply one to two teaspoons of TERRO® Ant Killer Plus over and around ant hills – water lightly immediately following application. If the soil is dry, water lightly before application to bring the ants closer to the surface for better control.
How to Treat Fire Ant Mounds
To control fire ants, apply ½ cup of granules over, and two feet around each fire ant mound. Immediately following application, water the product in completely, applying a minimum of one gallon of water to each mound area. Be sure to water gently – use of a high-pressure hose may disturb the ants and cause migration, reducing the product’s effectiveness!

"I get ants year round in my home. After trying other brands of the granules with little and short-lasting results I bought the Terro® ant killer plus granules, spread around the outside perimeter of my house and within a week there were no ants in my home. Great product and works as well as industrial grades."

Very disappointed. I live in New Mexico, high desert with many ants. I applied along my fence line where there's a lot of ant activity. Followed instructions on package to lightly wet after applying. Had absolutely no effect on the ants.
Thank you for taking the time to share your feedback. We’re sorry to hear you didn’t see the results you were expecting.
This granule product works by targeting ants that come into direct contact with it as they move through treated areas. After exposure, it typically takes up to 24 hours for affected ants to die, and it will not impact ants that do not walk over the treated zone.
We understand how frustrating heavy ant activity can be, especially in high-desert conditions, and we appreciate you giving the product a try. We’ll also share your comments with our product team.

This product is ABSOLUTELY AMAZING!!!!
It works wonders..I am ESTATC how well it works.. I put this in my yard over top of The Rocks, it was many types of bugs crawling throughout it...NEXT DAY I don't see any ANTS.
I don't see different types of bugs NOTHING!!.
I DID SEE a few dead water bugs too!
Product works BEAUTIFULLY, definitely has my vote , and will be buying again!
We're sorry to hear that you did not see the expected results.
For best performance, apply TERRO® Ant Killer Plus directly around and over active ant mounds and along ant trails when the ground is dry. Avoid watering the treated area or applying before rain, as moisture can reduce effectiveness. Large or established colonies may require a repeat application according to the label directions. Applying in the early morning or late afternoon when ants are actively foraging can also improve results.
We appreciate your feedback and the opportunity to help improve your experience.

Vivo en barriada, todos tienen mascotas y jardín. Pero las plagas vienen a mi casa y de paso las hormigas cosechadoras rojas colonizaron mi patio. Compré Terro Plus y cuando la señora no estuvo use todo el paquete en el jardín y le dí un buen remojon. Tengo la costumbre de darme una ducha relámpago cuando uso plaguicidas y al salir no pude ver ni una sola hormiga. Antes de usar el Terro Plus tenía vías de 4 carriles de hormigas. Quede Estupefacto ????. Las erradico en menos de 30 minutos. Nunca vi un producto tan eficaz. Mi esposa está feliz, le habían arrasado casi todo. Gracias.
I'm not sure what type of ant was in my house but there were small amounts of what looked like sawdust (frass) where they were spotted. If they were carpenter ants they weren't the larger black variety. I purchased a bag of TERRO Ant Killer Plus and applied it where the ants were outside of my house, and I haven't seen any more ants or frass since.
BRILLIANT DESIGN! I don't have to transfer to a broadcast spreader. Just shake and go! First time using sodont have an idea of effectiveness. But someone had a great idea with the shaker bag!
Toss granules under your house if you have no basement. Works!

I had a bad ant infestation and the liquid baits did not work. Treating the perimeter did not work. I have no basement. The ants had moved in under my house, probably to get away from the rain. I opened the crawl space access points outside and with a scoop I tossed the granules under the house trying to get all the space covered. Worked like a charm! I never had to repeat the process. One and done. Thanks Terro!
Spray doesn’t work. The liquid ant baits are great. They take a few days and you see a lot more ants in the beginning but then they are gone in area being treated. Can’t say about outdoor grains that you shake around foundation. Have to time treatment with rainy days which isn’t so convenient.
Thank you for this feedback. We're sorry to hear that the desired outcome was not achieved with this product. It will only help control ants that crawl through the treated area. If ants are continuing to swarm, we recommend additional methods of control such as baiting.
We recommend keeping children and pets off treated area until product has been watered in and lawn is dry.
