Terro® Ant Killer Plus

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

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 a Perimeter
How to Treat Ant Hills

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!

Five Stars

"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."

This ant killer has not ... worked to kill the ants in my yard.
Jun 26, 2024
This ant killer has not worked for me. I have treated the area at least a dozen times. The ants are gone for a day and then right back.

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.

Slightly watered planting area. Applied TERRO, then slightly watered again. It will rain all day in 48 hours. Do I cover the area with tarp or let the rain flood the area? When can I plant my floral seeds?

It didn’t work at all!
May 29, 2023
I bought two bags of this from Menards and applied to the edges of my lawn, then I watered it following the instructions. However, it did not do anything. After a few days the number of ants didn’t decrease and they are still very active. They even climb over the granules to go in and out of their nest. I wish I could get my monkey back!

I originally bought this product for ants, however my basement inside and outside was getting over run with millipedes! I decided to spread these granules around the perimeter outside. Fantastic! I don’t see any. This product worked for me.

Liquid ant baits are terrific
Jun 15, 2021
I've always loved the ant bait it does exactly what it say it would do I turned those base onto for my family members and they no longer have problems with ants however your bug spray don't seem to work that well I was disappointed I want to be a advocate for Terro because I believed in it, now the ant powder for the outside don't seem to be working that well I sprinkled on the side of my yard where my air conditioning vents by the tree were and I'm still seeing a bunch of ants crawling up on the air conditioning area where I applied the aunt powder, but the liquid ant bait is the bomb!

Soil condition after application?
Mar 11, 2021
It took care of our fire ants in the location we needed it. Unfortunately the location is where I planned my vegetable garden. We planted flowers instead last year. How long until it is safe to plant vegetables in that soil? It has been a year since the treatment

Great ease of use and seems to be working.
Oct 8, 2019
For ease of use I gave it a four. Not sure about effectiveness yet as I just used it yesterday but don’t see that many today. The gentleman at the store said to reapply after it rains in a few days. Got these ants from a nest in tree mulch. Thankfully contained to one are that I spread the mulch.

Does this product kill birds?
Sep 26, 2019
I am fearful this product will be dangerous to birds. They could eat the pellets thinking they are food.
