I love the smell of bee puke in the morning!
Yeah, me too...there is nothing like it on some fresh baked bread! Yeah, I still make homemade bread.... :-D
The spray type expanding foam works well to cover larger areas, as between studs....but be sure to caulk the little knot holes and openings! Bees will find a way in unless you use caulking! They can also eat their way in through the expanding foam to get where they want too.
If all of the extrances are full of caulk, they will leave it alone, as they cannot get in. In old structures, it can be and usually is a headache!
A friend of mine uses origional Dawn dishwashing soap mixed with water in a pump up type sprayer to wash down the honey drippings if possible. It seems to disperse the honey scent and cleans the areas pretty well. HE then sometimes puts a few drops of Bee Bee Gone in there to make sure they do not want to return.
