Walmart has the best price and quickest delivery

Walmart has the best price and the quickest delivery of Orto Orthene Ant Killer Powder than anywhere on the internet, and I know I have hunted for it everywhere. Also they always follow the delivery instructions to place it on the front porch to keep everything dry from these surprising Springtime showers. Highly Recommend!

Excellent product. Smells awful but it works. I use it inside and outside the house. Probably shouldn't use it inside but I do. No bug issues so far. I don't have babies or pets. The loud smell goes away after a couple of days. I suggest opening windows for a bit the first day.

Very effective and works amazingly fast

This is the only ant killer that has worked at destroying fire ant colonies on our property. This past year we had over 30 mounds develop. This product is real simple to use, just gently sprinkle a light coating over the top of the ant mound. We have seriously seen the eradication of 100% of a single colony over night. Although the smell is horrible, removing the ants is worth it.
