Will bleach kill ground bees and wasps?

Probably not fast enough to avoid getting stung. Ground wasps, or yellowjackets, are very aggressive and will defend the colony. We have a lot of moles so we get a lot of these nests. I have good luck mixing an entire quart of Sevin liquid insecticide into a gallon of water and rigging up a contraption to send it down the hole - through a hose - AT NIGHT. DO NOT try this during daylight. Set it up to drain into the hole (on a chair or milk crate) shove it in and run! Leave it there until morning and remove it carefully in case some survived. It is a good idea to cover your flashlight with red plastic to keep them calm while you set up. I have also killed them by emptying a can of wasp spray into the hole - at dusk from a safe distance - but it is a little more dangerous and may not get them all the first time. I have been told that Sevin dust will also work but may take a few days. Whatever you do, don't mess with them during the day!
