Spider spray
Unlike most I am fortunate to not have a spider problem on the boat. However, I have a detached garage that they like to make their home in. I recently tried Ortho Home Defense insect spray for the first time. It's a preventative, barrier type product. Spraying it around the perimiter of the garage seems to have killed most of the buggers, and prevented new ones from crawling in. It's supposed to be good for 6-12 months, I believe. Perhaps a spray application of this stuff along the dock and on the dock lines would be helpful.Randy
