We had muddauber hotels on board and finally found that Irish Spring soap 
would drive them out.We rarely had spiders, and if so, usually only outside.  
After the daubers were gone, the spiders came inside in numbers.  Suddenly the 
daubers don't seem so bad.Equilibrium eh?  Everything is connected to 
everything else.RonWild CheriC&C 30-1STL

 Boric acid is very effective, but the spiders have to come into direct contact 
with it for it to work. I use it in the garden and it protects against all but 
squirrels and neglect. Spiders may be less likely to wander into it though. 
For backpacking, I spray permethrin on shoes/pants to knock out ticks and 
mosquitos. It stays around for multiple washings, so might be viable for 
docklines. It says it's effective against spiders. 
We've been using moth balls on board for the past couple of years. They keep 
the mud daubers and spiders in check. The mud daubers eat the spiders, but can 
scare people. I prefer them to spiders. There are both still aboard, but far 
fewer in number.
The moth ball smell hasn't been a problem, so I haven't tried any of the 
alternatives but am curious if others have had success with them. Peppermint 
oil sounds nice!
