I have an infestation of daubers in my ski boat. I assume the product you recommend for house would work inside a boat as well?
I keep a boat on my local lake and have a constant problem with MUD DAUBERS making nests in all kinds of obscure areas. Some have been found under the boat tarps, inside cup holders, just inside vents and even in the bilge and motor compartment. As a general rule I have never sprayed anything liquid on my boat for both the fear of damaging the finish and contaminating the lake water. And since aerosol products tend to go on too greasy I’ve avoided them too. They typically contain all kinds of solvents which could affect the gel coat of my boat decking so I’ve stayed away from these products as well.
But that changed last year. Turns out one of the new aerosol products we have is ideally suited for boats. PT PHANTOM features a dry aerosol formulation that goes on without making a mess. I’ve used several cans of it on my boat the past two years and it’s not made a mark. My boat is mostly white and I don’t wax it but only a few times a year. However, it’s not showing any signs of being “sprayed” like one commonly sees with many liquid formulations when used in such areas. More importantly, it’s easy to apply and I find that treating in the spring through the summer will both stop and control nuisance boat pests like spiders, wasps, mud daubers and roaches. I apply some every 2-3 weeks; you may have to use it more frequently since your jet ski will get “wetter” through and through and this will depreciate the treatment faster. But you have a much smaller area to treat so one can should last a good long time.
