Size: 2 - 12 OZ Bottles Style: Mound Treatment
This works wonders! I had new neighbors move in and they brought all the critters with them! It was an infestation. Within a week of using this stuff, they decreased DRASTICALLY. Writing two weeks to one month, the bugs were completely gone. The smell is a bit overwhelming at first but you get used to it. Just clean it up ABs replace every few days if it’s such a bother. ... show more

    • Amazing
Size: 2 - 12 OZ Bottles Style: Mound Treatment
The best red ant killer ever. I have tried just about every red killer on the market, this really works. Within hours You could see it working, Checked on the mound the next day and it was completely wiped out. We are in the country with a lot of mounds, simple to use, Spread it over the mound and a little around it that is it. I have a lot of animals so I covered it with a large bowl Just to make sure none of the animals would lick it. Does have a kick of a smell when applying, but that was no big deal. Buying some more very pleased with the outcome. Worth every penny not to have to worry about red ant bites. ... show more

    • Works great, use responsibly
Size: 12 OZ Style: Mound Treatment
This stuff works incredibly well. Even less than the bottle says is needed, only a half tsp will wipe out a medium sized nest. The fire ants are terrifying here and I made the first significant strides in the battle against them when I used this stuff last year. Do NOT use this in your house. You should not be breathing it, and it smells terrible. Don’t use it in ditches or uphill from a waterway/pond unless there’s no rain forecasted for a while, and don’t use near a pond/river at all. It will kill important wildlife if you do. Per my research, a good several days to a week in the hot sun and soil will break it down and it will be okay, but fresh product getting into water will kill fish, toads, frogs, and maybe turtles. So please use responsibly based on how water flows near you and check the weather for rain before you use it. I treated dozens upon dozens of HUGE nests (like life-threatening to a toddler size nests) last summer with one bottle, so the bottle holds a lot of product. Price is wonderful for that amount. ... show more

    • Works for roaches
Size: 2 - 12 OZ Bottles Style: Mound Treatment
We had a pretty bad roach infestation. I saw on Tik Tok that this worked for roaches too. I had to order it to my BF's house in Cali and pick it up during my trip and bring it back home to PA with me because I couldn't ship it to me. When i tell you this worked like magic! Man... I spread behind my most problem area and in the morning my kid woke uo and texted me at work and said she had to sweep the dead roaches. I didn't even know there were so many! There's only a few stragglers now so going to spread again and hope to kill the rest. I still have more than a bottle and a half left too. It does stink a bit so i spread it at night and let it work it's magic. ... show more

    • Kills Roaches too!
Size: 12 OZ Style: Mound Treatment
This is the only product I found that actually kills roaches and keeps them away. I had a company come out and spray for German roaches. It killed the first batch, but when the eggs hatched, they just kept coming back. I sprinkled this stuff inside the cabinets around the stove & baseboard. It Does have a very strong smell so you need to open the window for it to air out a bit. But once that’s gone so are the roaches. I’m sure it works great for fire ants as well, but I’ve only used it for roaches and it’s amazing. ... show more
