We live in the mountains of North Eastern TN, and there are some REALLY NASTY spiders here. I killed a black widow with a body the size of the end joint of my little finger! I have some monsters in the crawlspace to. Is there an additive that raises the killing power of Suspend Polyzone? Is it ok to fog the crawlspace first, then a week later go in and spray?
There is not additive for the Suspend Polyzone to make it more effective against spiders really. You could add ExciteR with the Polyzone to give a faster knockdown during application only to all insects. Something like Onslaught Fastcap is also an option with both if you want a faster initial knockdown and a product more designed for harder to kill insects like spiders.
Fogging only kills those insect out in the open at the time you do so. You can fog and then apply a residual once the air has been well venilated.
