Helps to End Creepy Crawleys!

QuantumShopper May 11, 2025

Serious product for a serious problem! Follow directions carefully and it works like a charm. Since I live in Florida spiders, of ALL kinds, are especially problematic. Since using this product around our home it has worked wonderfully.

After exterminating “ spraying” for either bedbugs or roaches you need to watch out for seven days if in no sightings you're good if not need to repeat and repeat every 7 days till gone it's worth it. For under $200. professional mask sprayer and chemical. Saves a lot.

Kills scorpions, seems to last

Anonymous April 21, 2024

I was skeptical (seemed expensive), but I mixed one fluid ounce with a gallon of water and put it in a sprayer. We had scorpions in our yard last year and used another product to kill them (but it lasted only a month or two). I have seen four this year. But none, since I sprayed this a couple of months ago. I have to do the rest of the property, but this works. Subsequent treatments will use only 1/2 oz per-gal, so this turns out to be quite inexpensive for the number of applications required (which seems like will not be many). The clever bottle design that lets you measure by leaving one cap on is also very useful. I will likely never need another bottle, but if I do- I won't hesistate.

A "mass casualty event"

Anonymous September 3, 2023

Wow. After applying this (at 1.0 oz rate) there were dead bugs everywhere. Nothing was spared - spiders, roaches, beetles, ants, centipedes, even grasshoppers that happened to get on the porch where I had sprayed. Anything that could crawl had its legs pointing up towards Jesus. Had to get the broom more than once to sweep the carcasses off. They just kept dying. The only worse death and destruction I have seen was when a professional exterminator sprayed my house. That was a massacre that made my jaw drop. This came very close to that.

Very surprised

Mike October 6, 2023

This stuff is amazing. And I'm surprised how little you have to mix with a gallon of water. Looks like it's going to last for a long time plus not a single spider in sight now.

Not impressed

Richard June 22, 2025

The claims that this product "kills instantly" appear to be greatly exaggerated. My testing of this product involved dipping a toothpick into the insecticide and "antagonizing" a captured brown recluse spider (which was approximately the size of a Tylenol capsule in size) and repeatedly contacting the spider directly with the insecticide on it's legs, face and abdomen. There was no immediate, visible effect. Several minutes later, still no visible effect. Eventually, I resorted to allowing the spider to crawl up the toothpick - literally crawling over the insecticide - but this also, had no immediate, visible effect. It has been approximately 20 minutes and the spider is still quite active. Disappointing results for the price paid

Not impressed

Joy March 27, 2025

The only thing this seems to be doing for my spider problem in my house is bringing lots of them out of hiding for me to kill. I was hoping this would actually kill them. 60.00 is a lot to spend on something that doesn't even do the job but in fact makes things more terrifying.
