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!
HOW TO TREAT AN ANT MOUND
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.
HOW TO APPLY INDOORS
Apply lightly and uniformly to infested area. Pay attention to cracks and crevices, service ducts, false floors and ceilings, wall voids, around electrical and telephone fittings and equipment, around water and sewer pipes, under and behind cabinets, refrigerators and sinks; around windows and door frames; along base-boards; in attics and crawl spaces. The amount to be applied will vary with the site but should usually be in the range of 0.5 lb of product per 1000 square feet.
HOW TO TREAT A PERIMETER
Apply around windows and doors, porches, screens, eaves, patios, garages, under stairways, in crawl spaces, and other areas where pests hide. To help prevent the invasion of buildings and structures by these pests, apply thoroughly and uniformly to the foundation and crawl spaces where pests are active and may find entrance.
"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."

This stuff is a joke. Poured it directly on visible active areas and the ants are just walking through it and continue to thrive. How do I get my money back?
We're sorry to hear the product did not deliver the results you expected, and we apologize for any frustration this may have caused.
TERRO® Ant Dust performs best when applied as a light, even layer in areas where ants are actively traveling or entering the home. Using too much product can cause ants to avoid the treated area, which may reduce effectiveness. It is also important to allow time for the product to work after ants come into contact with it, as it may take a while to eliminate the colony.
For a refund, please return the product to the store where it was originally purchased, as refunds are handled at the point of sale.
We appreciate your understanding and hope these tips help ensure better results moving forward.

I will never buy this ...

I will never buy this product again. While it may really might be good, I could not read the directions, even with a magnifying glass, which were very tiny and printed in white ink on an orange background. The packaging is not user friendly, which renders proper application next to impossible. I ran out of dust before the job was completed as I had to guess at the application rate. My mistake for having bought it. Never again.
Thanks for your feedback. We’re sorry to hear about your experience.
Clear, easy-to-read instructions are essential, and we understand how frustrating it must have been to struggle with very small text and low contrast printing. That’s not the experience we want for our customers, especially when it impacts proper application and results.
Your comments about the packaging and difficulty determining the correct application rate are important, and we’ll be sharing them with our team for review and improvement.
We appreciate you taking the time to share your experience. It helps us do better.

ant dust does not kill on contact as info states it would.
I have hole in the ground type nests of fairly large ants. I tried the stake liquid bates they ignored. Then have tried ant dust numerous times. It does make them almost disappear for a couple days then they're back. I put a thick solid ring of the dust around the whole 3-4" diameter. They have to walk through it. Not working and don't know what's nest.
I bought this based on the 8 month ant free claim..Don't waste ur $.Its over a week and the beds still have ants tho some have moved and started a new bed just over from the old one.
packaging deceptive and adds more plastic into enviroment than necessary

May be a good product but I have not used it yet. I had it sitting on a windowsill and could see that the container was less than 1/2 full. The container is 81/4" tall with 4" of product in it!!! Disappointing that the company is deceptive.
This product settles during shipping (just like a bag of potato chips). The bottle is filled by weight rather than volume. When the bottle is opened, it may not appear to be full, however the weight is correct. Please feel free to contact us at 1-844-837-7644 for assistance.

DOES THE ANT DUST KILL ANTS WHEN THEY BRING IT BACK TO THE NEST. OR IS IT A BLOCKER , I WANTED TO TREAT A VERY LARGE INDOOR CRAWL SPACE, MADE OF CEMENT. I WANTED A PRODUCT THAT THEY BRING BACK TO THE NEST. THANKS
Hello Mike! This product kills ants once they come in contact with it, rather than being taken back to the colony. If you prefer a bait, our liquid ant bait is a great option!
Best regards,

How long after application can my dogs be in the area with the dust?
Question by: Josh on Nov 20, 2024, 2:29 PM
Hi!
We recommend using the product in areas where there is not too much human/pet activity.
Answer by: Victor (Admin) on Nov 25, 2024, 3:13 PM
I have sprinkled product in various infested areas outside and near and on their ant hills, it doesn't seem to be affecting the ants. Am I doing something wrong?
Question by: Debbie Harrison on Jul 25, 2025, 4:38 PM
It sounds like the ants aren't being affected immediately. This is likely because the product needs some time to work.
For best results, make sure you're applying the product when temperatures are between 65° and 80°F.
Since it kills on contact and provides long-lasting protection, you should repeat the application if you still see active ants after a few days.

Can I spray or drop these product into the cavity of the tree they are in?
Question by: Kris on May 18, 2026, 2:26 PM
Hi, thank you for reaching out. Yes, you can apply TERRO® Ant Dust directly into the cavity of a tree where ants are living. This product is specifically labeled for both indoor and outdoor use and is effective for "crack and crevice" treatments where pests like to hide.
Answer by: Guillermo (Admin) on May 18, 2026, 4:08 PM
Will this work on argentine ants
Question by: Cameron Burrell on Jun 7, 2026, 8:52 PM
Yes, TERRO® Ant Dust can be used to control Argentine ants. Apply the dust in a thin, even layer in areas where ants are active, such as around building foundations, entry points, cracks, crevices, and along ant trails. Avoid applying thick piles of dust, as ants may avoid them.
For best results, keep the treated areas as undisturbed and dry as possible so the ants can contact the dust and carry it through the colony. Always follow the product label instructions for application and safety information.
