Spiders in my boathouse
 

They live in the roof and poop all over my boats. I can get the mess off with bleach and water,but I would rather eliminate the source. Any one have any luck with insecticides,if so,what brand. Thinking if I can spray all under the roof and rafters with something strong,I can get rid of them.

Just call a pro and hold him accountable to eliminating the spiders.

Every spring I pressure wash everthing down and coat with a spider spray. Works pretty well. Also, alot of people hang a tarp or plastic over the boat from the rafters.

What is the name of the spray ? They are worse this year in our area than i've ever seen. My full cover looks like its polka dotted with ink :eek:

When I used to keep boats in a covered marina they would spray 2-3 times a year....the one year they didn't it was OBVIOUS!!!! Never knew what they used but it did work.

This is probably more work than needed but I've seen some friends of mine paint the ceiling of the boat house a sky blue color. Apparently the spiders think it is the sky and they do not nest there. I was calling bull$hit on this too until I saw both a boat house and a covered porch painted blue and there wasn't one spider on it. Living in Texas on the water we have some big nasty spiders to. Good Luck

I hired a pest man to do our boathouse when he came to do the house and did it once a month and cut out 80% of the spider chit,but had to keep the geese from chittin on the dock then.12 gauge fixed that.:D

Chester takes care of that at my place :D

:D Yes he does but if he could only catch and get rid of those bass boaters that like too see how close they can get to your dock when coming around the bend.That would be a good dog.:D

I take a telescoping pole used for pool cleaning and duct tape a can of fogger(D-con, Raid, Hot Shot) to the end. Hit the button and wave it under the roof until you run out. Repeat as necessary. Easy to do and keeps them at bay for a few months.
