Help! My whole family is angry with me! I had a tree-trimming company that contracts w/ the power company come and deliver its 'free mulch' today in my yard, by my front door. It is an entire truckload - enough for 5 yards! I do not, of course, know what trees were just cut to make it. In addition to now having to pay someone to take the leftovers away (70% of it), and it killing the grass under it that I DID have, there are bees everywhere! I noticed them about an hour after the dropoff. They look like baby yellow jackets - are those sweat bees, or maybe baby yellow jackets? They are swarming in and around the mulch. I'll have to find a way to get my daughter past it, drop her off at Vacation Bible School, then come home and spray, I guess!!??? What could have happened?????? Do those traps work?? THANKS!!!!!!!!!!!!
