I'm curious as I guess alot of us are that you aren't familiar with wasps or mud ( dirt ) daubers. Where are ya from Scott - I guess alot of us that things for granite and know the difference between those nice daubers and those leg hang'n, bad attitude wasps. Those wasps could care less about helping out with the spider population - they'll stang ya 3 times each before you can say " *%$#@ , my, my that hurt " !! LOL Watch out ........ Steve - SC
