  • Wish that could be a rep for them because this product has saved my home here in florida
Size: 32 oz. Style: Concentrate
You cannot go wrong with any ortho product. Let me tell you I lived in Florida and the fire ants, and anything else that you can think that has wings or that can fly in your eyes or ears is here. So make sure that you get at least 1 to 2 extra bags, because no matter what you will use this. I use a strainer. That I used for pasta and then I tap a plastic cup along on the side, and uh, bend over and walk along my entire property. I may look like an idiot, but I'm the only one that lives here in Florida, that can lay in their yard and with their dog. Not be 8 up or have to lather myself in off, so do yourself a favor make sure you get it down in the beginning of spring and then the beginning of summer, it will not hurt. Any of your plants were your dirt or anything. My grass even grows better due to all of the bugs eating all of the nutrients out of it. So as hard as it is to grow grass in florida, this will allow you two.Have it thick and very nice. Also makes it amazing that you can weed eat with your hands without having to spray yourself down because if it has not rained, this stuff stays active day after day after day. So yeah, there's no way that this in any way, is a waste of money ... show more

  • Great product.
Size: 32 oz. Style: Concentrate
Used it once around the foundation of my house and in my landscaped areas. No more ants. Just remember that you need a certain type of applicator to use this product. Luckily, I had an applicator.

  • Stealth Killer, powerful insects destroyer
Size: 32 oz. Style: Ready to Spray
It works great on my lawn. I hooked this insect spray into the garden hose, and circled spray it into the infested areas. The results were phenomenal, it neutralized the critters on contact. Buy it, try it, see the elimination at work!

  • UPDATED: Fleas are complicated. ORIG: Fleas living and prospering after 3 spaced spraying sessions
Size: 32 oz. Style: Ready to Spray
EDIT: I gave this product only 2 stars originally. But after doing research and following recommendation I managed to resolve my backyard flea problem with this product. The problem with fleas is that they sort of "hibernate" in hard shell cocoons. And its impossible to create a chemical product which is safe (non-toxic) and kills fleas in all stages: larvae, cocoon, adult. If you make such product, it would be highly toxic for humans too. With my overly simplistic approach I sprayed 3 times, but I just did nothing in between these spraying sessions. Teenage fleas hide in impenetrable cocoons and can stay there for months. They get out of their cocoons when there is a potential meal walking nearby. So I decided to combine the poison with luring the fleas out of their cocoons. I walked around the backyard, stomping and slightly jumping to cause surface vibration. Then I sprayed the yard. Now, after couple of such sessions the fleas are finally and completely gone. Summary. This poison is just a good tool. But you also need to know how to use it correctly. ORIGINAL: I have a tiny backyard closed with a fence. A few stray cats visited and left some guerrilla combatants in a form of fleas. I made sure that cats couldn't trespass anymore and decided to use this product to kill fleas. I sprayed once. No result, same amount of fleas. Sprayed second time after a week. Less fleas, but still a lot. Waited another week and sprayed the third time. Three days past, there are much less fleas, but I still caught 3 fleas jumping on me. And even a single flee is too much. I must be zero. This product definitely doesn't work. Remind you, there are no more cats. ... show more
