The active ingredient you are looking for is Dichlorvos which your product contains 19.2%. That is higher than the 18.6% I have in mine. That's very strange it didn't work. How are your grow conditions? I also cut all ventilation for only 3 days and ALL BUGS died. That was a couple weeks ago and haven't seen shit since. And if they do I'll buy another one. I dunno what's up with yours. My product is called "Hot Shot No Pest Strip"
