CIPERTRIN T INSETT CONC 1 LT

This is the real deal but read the label, read online about the chemical and follow safety instructions.It should not kill arachnids but if you double the dose it does, and it stinks for a couple of hours but the spiders leave or kill themselves or something because I find dead ones after.A word of warning! If you have a spider infestation and you spray this, get someone who isn't afraid of them to come over with something to whack them because there will be an EXODUS like the gates of spider-hell are open and its party time!
