Okay, I'm here but too late. [:(] Damn, my one big chance to maybe be helpful and I'm busy working my real job. I couldn't help with the plumbing ? cuz all I know is doodie runs down hill. The pic looks like a cicada killer wasp. If so, they are not aggressive to you. They are hell on the noisy bastard cicadas though. Watch out for the baldfaced hornets and yellow jackets. They are rough/mean. I have to go in an hour to kill a nest of hornets. Usually it's no big deal but these bastards are back in a bush which provides lots of protection from me. I am terrified and have butterflies in my stomach as I type this. Exterminators and animal control people won't mess with them. I'm the only one the locals have, so I get lots of calls. Risking my life for $40.00--I must be nuts. QuietShootr, I honestly don't know if they will/can sting you when you mow over their burrow. I doubt it but don't want to give you bad advice. I would suggest you go to the library (or the net) and look it up. "Cicada killer" is their correct name to look for. Those of you with B-faced Hornets and yellow jackets, here's a secret--always attack in the dark, and squirt some shave cream in the hole at the bottom. If hornets, and the nest is at the end of a branch(typical) you can cut the end of the branch and then slip a garbage bag over it and cut the branch, letting it fall into the bag. Close it good, then put in the freezer for [b]several[/b] days. Freezing kills them. This is best done with a beekeeper's protective gear, just in case. Yellow jackets have to be directly attacked. Their nest is similar but always on/in the ground, not a tree branch. Use a suit, LOTS of instant-kill spray (make DAMN sure it's instant kill!!) tear it open, and spray like hell until they're all dead. Few things are more exciting than this kind of a fight to the death. Oh, both need to be done in the dark as that is the only time they are all in there. Also, keep the ambient light as low as possible as they can't see in the dark. Pucker factor--high.
