Compare-N-Save 7.9% Bifenthrin Concentrate for Insect Control, 8-ounce

I purchased the 32 ounce concentrate back in October 2023 after reading many reviews. I live in NC where we have tons of crane flies that lay their larvae in our grass. I also purchased a 2 gallon ELECTRIC spray tank (got tired of needing to pressurize my other one every 5 minutes--well worth the price and time saving). I wanted something that wouldn't injure bees or birds. After reading through the very confusing directions on what concentration to use in certain areas, I just decided to use the 1ml/gallon. I sprayed every inch of my Bermuda grass, the entire perimeter of our home, the faux stone on our home, around each entry door of our home, our rosebushes, perennials (azaleas, hibiscus, gardenias, daylillies, etc). It has now been 6 weeks since I spent 2 solid days doing only the outside of our home. We have zero grass bugs, flies, spiders, ticks, aphids or crane flies! Hooray! I can now lay down on our lawn and play with my dog without having bugs crawl all over me. Bees, hummingbirds and other birds are all doing well. ***I made sure to spray only the bug sensitive perennials BEFORE any blooms appeared as well as the mulch around the plant to kill the beetle larvae from emerging. I have not done any internal house spraying, but I haven't seen any bugs or spiders inside at all. Very happy with result so far. I'm not sure how long the results will last, (has already lasted 6 weeks and they said "the results will vary," but a 32 ounce concentrate did 5,000 sq feet of lawn, external house, stone, etc. and I have about 8 ounces left. All my neighbors are now looking at this product too! Less bugs for us equal less frogs and snakes attracted to our yard so that our kids can play worry-free.

Saving me tons of money. Works great. I applied a couple of times because I think it takes a day or two to work but it worked great.

Killed our infestation of red wasps fast. One treatment. Great stuff.

Product is effective, especially on ants. Lambda-Cyhalothrin seems to work better on spiders but rotated monthly or mixed is the best. Packaging could be improved as every bottle seems to leak during shipment, this last delivery the top either wasn’t screwed on or got dislodged during shipping.

Cancelled my bug guy because of this product.

I have not seen any spiders where the spray has been sprayed. It does not do anything with flies but crawling bugs arent around any more.

I think it worked pretty well for keeping bugs out of my house but it did leave a white residue where I sprayed it. It also didn't kill on contact when sprayed directly on bugs which I sort of expected it to do. You do have to mix the product to use it so you need to have something to spray it from.

I live in a bug-prone area (Texas humidity = roach heaven), and I was losing the battle — ants, spiders, fleas, even some wasps hanging around like they pay rent. I got this after a friend swore by it, and now I’m swearing too — just not the same way 😆 Mixed it up in a pump sprayer (1 oz per gallon), hit the baseboards, windows, and the whole perimeter of the house. Within a few hours, dead bugs everywhere. It’s like a massacre happened on my porch. It doesn’t stink like some sprays, dries clear, and doesn’t bother my dogs once it’s dry. Best part? It keeps working. I haven’t seen a live ant in weeks. Not even the bold ones that walk across the kitchen counter like they own it. If you’ve got a pest problem and don’t want to spend $$$ on pest control services, this is a no-brainer. Just use it safely, and don’t let it near fish or water runoff — it’s serious stuff. But damn... it works.
