    • Good pest control
Color: Quickhand Sprayer
Very easy to use. I sprayed on baseboard wall corners. After 1 week anything that tries to get past the barrier is no longer able to crawl. His stuff works! Easy to spray, the nozzle is effective in leaving a quick sprayer or longer stream. His product is safe for my home, does not smell or leave any residual odors, and the price a little more than I expected for the amount of liquid in the bottle. Overall it was a good investment. Will be being another one later! ... show more

    • Great for keeping bugs out of the house
Color: Quickhand Sprayer
I’ve been using Ortho Home Defense Max around the house, and it has made a noticeable difference. I was seeing more ants, spiders, and the occasional other insect getting inside, especially around doors, windows, and baseboards. After applying this along those areas, I’ve seen significantly fewer bugs indoors. It’s easy to apply, dries fairly quickly, and the 1.5 L size gives you plenty to cover a good-sized home. I especially like being able to treat the areas where insects are most likely to enter rather than having to deal with them after they’re already inside. It’s definitely become part of my regular home maintenance routine. For the price and the amount you get, I’m very happy with it and would recommend it to anyone looking for an easy way to help keep household insects under control. ... show more

    • The Best Ever
Color: Quickhand Sprayer
This is the best spray I have found, after trying multiple other brands. One application and I haven't seen a single spider inside my home, and we had been overrun with Cellar Spiders and Black Widows.

    • Ants are finally gone
Color: Quickhand Sprayer
I sprayed outside and it worked to keep out ants from the inside. I haven’t seen them. Love the handle and automatic spray. Downside it’s probably not enough for a big place! I live in a small studio and I’m already at half the bottle enough for another treatment if I need it. Easy to apply and doesn’t smell bad at least outside it didn’t. Hoping it last all year like it says. ... show more

Lots of product for the price, takes about an hour to completely dry, so keep pets away during that time period. Great for inside trash bins too! Simple lock and safety features
