As an exterminator of over 32 years let me tell you,,,,,, this stuff is junk. .. You have to drown a bug to kill it.. Ive used the Eco Via EC plenty of times with no problems. Bottom line, if its made for California don't use it..
I like this stuff! I was able to see a bunch of dead moths that emerged from a crevice a few days after spraying which was really satisfying.
I ordered two cans. On both, the injector straws were brittle and cracked. I managed to salvage one of them but not ideal.
