Home is 7 yrs old, told I'll get another 30 yrs out of my beautiful wood shake roof. Only problem is we have an unrelenting silverfish problem. Multiple companies have put "as much chemical as I can legally put on this house" without getting rid of them. The only relief we got was when a guy fumigated the roof itself. Locals all say silverfish will always be here as long as I've got that wood roof.
Bifen IT can be sprayed onto and into the shakes to provide some relief from the silverfish. Be sure to use the highest usage rate of 1 oz of Bifen IT per gallon of water for the fastest knockdown and the longest lasting residual. You will need to reapply once a month to keep up the barrier.
