TERRO® Ant Dust

Take control of pests inside and out with TERRO® Ant Dust. This waterproof powder kills on contact and lasts up to 8 months. Killing fire ants, carpenter ants, cockroaches, spiders and much more makes this a staple for any household. To help prevent and control invasions, apply TERRO® Ant Dust thoroughly and uniformly to foundations and crawl spaces where pests are active and may find entrance to your home. The dust acts as a barrier that the ants and other insects must crawl through, ensuring contact and therefore killing them.

Easy to apply


TERRO® Ant Dust comes in a convenient, easy-to-use shaker can. Just twist the inner cap to allow a scatter of dust through small holes or a wide spread option through the large opening. Twist again to close or adjust!


To treat fire ant mounds, evenly sprinkle approximately one tablespoon of TERRO® Ant Dust over the top of each mound. Do not water in or disturb the mound. Apply when temperatures are between 65° and 80°F and allow three to four days for maximum control. Repeat application if ants are still active.

"I used Terro Ant Dust for years in combination with other pesticides like Terro Ant Bait and much more. Works great and last long along with it being waterproof. I live in a heavy wooded area and for the last 25 years I have been keeping carpenter ants along with others at bay."

Product Questions

How long do you keep the dust out? And how do you get rid of the dust?
Question by: Hailey L Feind on Sep 16, 2017, 8:00 PM
This product will be effective for up to eight months after applied. We recommend removing the dust when the insects are controlled. To clean, please sweep all the traces of the product into a pile, vacuum, and then wipe down the areas with soapy water and rinse. Gloves should be worn when cleaning.

How long do I leave the powder during indoor use? This is not mentioned anywhere on the product at all. Leave it till its gone? Like have a bunch of powder sprinkled around until no more ants appear? Or they wat it all?
Question by: Dafishyg on Sep 27, 2016, 8:00 PM
When applying this product indoors, the application area should be limited to crack and crevice areas, under and behind cabinets, refrigerators, and sinks; and around windows, door frames and baseboards. This product should not be spread on carpets or in areas of heavy traffic.

The dust will last up to 8 months and does not need to be cleaned up during that time. Keep in mind that only a light dusting of the product is needed.

I bought this product to place around our foundation to keep all the ants out. Since then I discovered the ants have taken up residence in a long tile shelf built / attached onto the outside of our house (sits directly under kitchen window). The product directions instruct to apply around doors and windows etc but how can I apply this powder around the widow and around the shelf? Won't it just all fall to the ground? I don't understand how to apply a powder around something like a window.
Question by: tiptoe on Sep 6, 2017, 8:00 PM
Using a paintbrush or other small brush, the dust can be pushed into cracks and crevices where ants will crawl as they try to make their way into the home or onto the shelf.
Answer by: Woodstream (Admin) on Sep 6, 2017, 8:00 PM
I’m installing a new paver patio. There is an ant infestation along the wall where pavers will be installed. I’ve just sprinkled the dust along the wall and hoping that it works. I’ll probably have to retreat same area in future and would like to know if the ant dust will damage my new pavers
Question by: Deb on Jun 29, 2018, 8:00 PM
