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."

Product Questions

Will it harm plants?
Question by: Virginia on Apr 30, 2019, 8:00 PM
This product is not recommended for use in vegetable or fruit gardens, although, use around the perimeter of the garden is OK. The granules will not harm your landscape plants and flowers.

How long before granuals disappear after applying product? And whats best way to clean up annuals after applying them and how long are they active?
Question by: merg on Jul 28, 2015, 8:00 PM
After the product is applied and watered, the active ingredient rinses into the ground. Over time the granules will decompose and there would be no need to clean them up. The product can be reapplied as often as every two months.
Answer by: Woodstream (Admin) on Jul 30, 2015, 8:00 PM
We applied this product to our yard because we have tons of ants. We also have a dog.

Your warnings are all about aquatic animals, not about furry animals. We want to know when we can let the dog into the back yard again!

Question by: Sharon on Jul 14, 2020, 8:00 PM
When applied as directed, it is safe for pets to re-enter the treated area once the product has dried.
Answer by: Woodstream (Admin) on Jul 15, 2020, 8:00 PM
Why can't we see the label to see the active and inert ingredients to compare to other products?
Question by: cjd on Feb 9, 2017, 7:00 PM
The ingredients can be seen on the specs tab on the instructions PDF.  The active ingredient is Lambda-cyhalothrin (0.04%).
Answer by: Woodstream (Admin) on Feb 22, 2017, 7:00 PM
Does this also work to keep spiders away from foundation and coming into your house?
Question by: linda on Sep 12, 2015, 8:00 PM
This has not been tested on spiders. We would recommend the TERRO® Spider Killer Spray (Model #: T2302-6).
