TERRO® Ant Killer Plus

Keep ants and other unwanted insects out of your house with TERRO® Ant Killer Plus.

Ant Killer Plus
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." Read More Reviews »

Great ease of use and seems to be working. By Bees

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? By Michael T.

I am fearful this product will be dangerous to birds. They could eat the pellets thinking they are food.

Too good to be true By Nattie

I thought I had found my dream ant killer for my lawn and flower beds. Ants were gone in 2-3 days. I was overjoyed. Package said it works for 3 months. I would have been happy if I only had to use it every 1-2 months. 1 week later the ants were back with a vengeance. Tried again just to make sure it wasn't operater error. Same thing happened again. So disappointed.

Problem dispensing By Ron

How do you dispense the product. I open the zipper, spread it open, turn upside down and shake hard and nothing comes out. I have three bags of this stuff and have the same problem with each bag.

Response From Terro®
Jules : Consumer Relations Representative

Hi Ron! We're sorry that your Ant Killer Plus bags are not allowing you to spread this product easily. You should be able to unzip the bag, turn the bag upside down, and shake the granules out without trouble. We recommend making sure that the plastic, re-sealable zipper stays open, and doesn't close. For further assistance, please give us a call at 800-800-1819 x 458.

Defeats Carpenter Ants By Mckjanet

I had been fighting Carpenter Ants for 6 weeks... seeing only 3 or 4 a day ...bought every liquid bait and granule known to man, as well as trying “for sure” home remedies... the ants kept roaming around ... bought Terro granules, also cockroach gel bait, didn’t see the ants go to the gel bait but they were crawling and dying in the granules... 2 days later not an ant in sight... still nothing 5 days later... tempted to cancel the exterminator appointment I made last week

Works well especially if used on schedule By Mel

Seems to work well. Best if you plan a schedule. Do not just wait till insects start to come back for best results.

Q.I bought this product because it's so dry and hot outside that ants are trying to enter my home. I used this around the perimeter of house for days ago. Still plenty of ants. Am I supposed to water it every day? I only watered it the first day

This product should only be watered in once. Ants that come in contact with the treated area will die within 24-48 hours.

Q.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!

When applied as directed, it is safe for pets to re-enter the treated area once the product has dried.

Q.Can the granules be applied to ant hills if it's going to rain the next day? What time of day is best to apply?

This product may be applied prior to rain. We do not have time of day recommendations for application of this product.

All About


There are more than 10,000 known species of ants living throughout the world. Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae and powerful jaws. Ants are social insects that live in structured nest communities throughout the world. The species of ant determines whether they live underground, in mounds built at ground level, in wood structures or in plants or trees.

More About Ants


I need to knock out an ant invasion quickly – what do you recommend?

Since most ant infestations are linked to a colony located outside the house, we suggest using our fast-acting TERRO® Ant Killer Plus Granules for instant knock down of ants, cockroaches, fleas and other insects. This product also provides long lasting repellency and it’s super easy-to-use; using the convenient shaker bag, simply apply the granules around the perimeter of your house for an instant kill and long-term insect control.

What is the best way to treat an unusually large ant invasion?

Ant populations that have become quite large sometimes require more than one treatment. We recommend the following two-step process to control large infestations.

STEP #1 –Bait Worker Ants

The first step to successfully controlling ants is to lure worker ants – those that you see marching around inside your house – to TERRO® Liquid Ant Baits. The ants will consume the bait and carry it back to the nest to feed the Queen and the rest of the colony. While the insecticide in the bait will ultimately kill the worker ant, it works slowly enough that the worker has time to get back and share the bait with the colony.

STEP #2- Create an Outdoor Barrier

Since most ant infestations are linked to a colony that is located underground outside the house, the second line of defense is setting up a barrier around the perimeter of your house with TERRO® Ant Killer Plus Granules. The granular ant killer kills pests on contact and provides long lasting residual repellency. The Ant Killer is packaged in a shaker bag for easy application- no spreader is needed. After applying the granules around the foundation of your home, water in lightly.
