Sound of water spilling over my gutters caught my attention today.
Looking from the ground up it appears a mud based nest may have been
built in the gutter. Not uncommon around here for types of mud wasps
to do so.

Considering the top should be exposed to the weather is there some type
of spray that might help the rain destroy the nest?


Disclaimer: all this may be revised once I get time on a dry day to
actually see what is up there.
