THE CEILING OF MY BOAT DOCK IS INFESTED WITH MUD DOBBER NESTS THAT KEEP FALLING INSIDE THE BOAT. WHAT DO YOU RECCOMEND THAT I SPRAY THE CEILING WITH AND DO YOU SELL THE PRODUCT? PETER

No doubt mud daubers love boat docks and boats. I happen to keep my boat under a covered dock and have the same exact problem. But I found a cure a couple of years ago and its easy to do, clean and works great. I only have to treat 2-3 a year.

First and foremost, its not a liquid spray. As you can imagine, using a liquid would be messy (and dangerous for the water under the dock) so the Cypermethrin we mention in our MUD DAUBER ARTICLE is not an option when dealing with a boat dock or any other place thats over water. But a few years ago an aerosol came to market that goes on “dry”, is odorless and works well for many insects including spiders and mud daubers – the two I get at my dock.

I actually use it on my boat about once a month. Basically I mist the railing, rod holders, trolling motor, etc. to keep everything off my boat. I also spray the boat covers (two large ones) twice a year so mud daubers don’t make nests on the bottom side which they tend to do during the spring/summer.

For the dock roof, I use a long extension pole aerosol sprayer combination we carry. It holds the Phantom aerosol can and comes with a long “pull string” cord I pull when I want to spray. Basically I extend the pole up around 12 feet to reach the ceiling and then lightly mist the sections of the roof where they like to nest. The Phantom isn’t a quick kill; it takes about 2-3 days to work. But insects don’t notice or mind it so they readily walk over the treatment which is very important. In the end, they all will die within a few days.

I suggest getting the Phantom and one of the pole setups depending on how high you have to reach. This investment is well worth it. Oh, and you can use it around the home too for spider webs, etc. Great tool.
