Kills Anything -- Some Faster Than Others
April 2, 2012
The active ingredient in ECO-PCO ACU is 2-penethyl-propionate. It is derived from alcohol and targets a neurotransmitter that only exists in invertebrates (a.k.a. bugs). Therefore, there is less risk to the human nervous system and it is labeled a natural product.
This spray will drop house flies (even gigantic horse flies) instantly on contact. They'll crash and burn like The Hindenburg blimp. If you hit a larger crawling bug like a spider, house centipede or jerusalem cricket, IT WILL definitely die but it can take 1 minute to 5 minutes.
The more powerful concoction of this product for crawling insects is EcoExempt KO. EcoExempt KO is FIVE PERCENT (5%) 2-penethyl-propionate, whereas ECO PCO ACU is only 0.10% 2-penethyl-propionate. The tradeoff is that EcoExempt KO is NOT a misting aerosol and so is less useful against flying insects. But EcoExempt KO will disable large crawling insects (and by LARGE I mean Jerusalem Crickets, which are the size of a small mouse) instantly -- and kill them more quickly than this product.
But make no mistake -- ECO PCO ACU absolutely kills on contact like it states. None of my hundreds of insect victims of every size ended up living . . . just understand that if your goal is instant knockout of crawling insects, another product by this manufacturer (EcoExempt KO) is a bit more "instant."
