BASF Advance 375A Granular Ant Bait, Indoor or Outdoor, Kills Fire, Odorous House, Carpenter, Little Black and Argentine Ants, Ready to Use, 8 Ounce

Although it's fairly expensive, a little bit goes a long way. This is the most effective product I've tried for carpenter ants. Better than sprays or generic ant killer. Sprinkle some in areas where you see the ants or expect they will be and over the course of a few days they will disappear- ants carry the bait back to the nest

Professional strength. Gets ants gone. If you live in a rainy area, consider buying plastic bait stations to put it into so the rain doesn't constantly wash it away.

Out of the blue, we had little, itty-bitty, black ants traveling in our kitchen. (Ugh) These were smaller than even the typical little black "pavement" ants you'd see outside. We tried a few other products that slowed the ants down (including 50% boric acid/ 50% powdered sugar), but we could tell that the nest was still active. My father had recently conquered his ant problem and recommended we try the "Advance 375a". Well, after we sprinkled some of these granules to the area where the ants were traveling in the kitchen, the ants simply disappeared! It took less than 2 days!! We put the granules down on April 22, 2019 and we haven't seen them since!! Not even ONE!! Simply wonderful!!I've come back here to give a tip: The ants we had were so tiny that the Advance 375a granules were too big for them to grab and carry, so I took a small amount (like 1/2 tsp) of the granules and placed them in a sandwich-sized zip-lock baggie. I squeezed out the air, zipped it up, took a hammer and proceeded to pulverize the granules. I shook the bag around a little and hammered it again! I did this several times until I was satisfied that it was as pulverized as I could get it!. Then I sprinkled the contents around, and was pleased to see the ants were able to grab their bite-sized meals & go!!

Product works well, a few sprinkles and the next day the ants are gone. I dinged it one star because the container is barely half full! (If you think you are getting dinged with your cereal, this is way worse.) Based on the size of the container I thought it'd last me a year or so, but, NO! A more honest posting would have a container more appropriate to what's in it.

For some reason the carpenter ants don't seem to touch it. They look for something else and pass right by it.

The best product for ants I recommend for everyone who have this problem

Unbelievable... it Works! Amazing how fast this works on ants! Kills quickly !

I like how well this product works. However both times I've ordered it through Amazon, the seals were broken and the containers half empty..
