Do any of you midwestern sailers have a solution to keeping Mud Dauber wasps out of your interior? I have taped over the ventilation louver between the hatchboards on the inside, but I need the ventilation. Even when the louver is taped, the little pests get in through the cracks at the corners where the sliding top meets the hatchboards. Have never been stung, but the mud nests they build inside are a pain in the rear. While we're at it, what are the best ways of providing leak-proof/bug proof ventilation on the catalinas without hurting the original good looks? Steve Perry '89 Catalina 25 "Love & Luck"
Steve, we use hanging plastic pest strips available at Tractor Supply on East Kellogg (or West Kellogg, too). Mud daubers won't even come into the boat when those are present. I can't remember the brand name but it was posted on this web site last year.
try a netted bag with mothballs. hang it in the cabin. they will not enter and you will smell like you have been stored in grandma's closet. dave holtgrave 5722 sk/tr sailing carlyle lake in southern illinois
Cut two strips about 1" long from a flea collar for pets. Use double-sided tape to attach them to each side of the companionway "holes". On "TSU" I used screen material to cover the louvers, screwed to the back of the top companionway board with brass strips from a hobby shop - looks very neat. Derek
The pest strips are probably not going to hurt you on an overnight, but I wouldn't hang them for a weekend on the boat or an extnded voyage. I put mine in a plastic freezer bag and store them under the stove. Just remember to hang them when you ae away. They work for every bug, big or little.
Somewhere I read that a Flea Collar for cats would work. I hung one of them in the cabin late last summer ... so far so good. But, it's pink :( Perhaps I'd better get another. If it goes all summer long with no incursions I'll let you know.
Another remedy: Go sailing! In our club, the boats with muddauber nests are those that don't leave their slips for a month at a time. That was me a couple of years ago, when they nested in my main and my roller furling jib. Wasps generally can't find your boat or their nests if you move the boat even 50'. If you go for most of a day, they'll find another place to start building. (They're active only during the day.) You definitely don't need protection like No Pest Strips when you're on a weekend cruise--the wasps won't have the faintest idea where you went, and won't be looking for you overnight.
I have a problem with wasps, in addition to mud daubers. I keep some prednisone in my first aid kit for wasp bites. I'll try the pest strips, and add some screening to my hatch covers The mud daubers already put stains on my brand new Ullman headsail.
I made a sunbrella hatch cover that snaps onto the same snaps that are used for the pop top cover (on either side of the hatch). The cover is long enough so that, after it is snapped in place, I can flop the top over the top hatchboard. Then I pull the sliding hatch over it. It not only closes the vents in the hatchboards, but it also helps close the space between the sliding hatch and the top hatchboard. It also helps close the space around the hatch slides. Now, I rarely get mud daubers inside the boat. It was easy to make and it protects the finish on my hatchboards from UV rays and weather.
