I'm the self-anointed bug catcher-and-releaser in my office. I even have a couple sizes of glasses ready for the catching. *g* So long as the bug is on the plus side of the register (does more good than harm), it gets rescued and released to the streetscape outside. Much to my surprise earlier this summer, I got to apply this policy to a full-grown praying mantis which had become trapped in the revolving door of the bank building opposite us. (That time, I had to beg a cup from the Starbucks in the lobby; nice clerk was helpful.)

Recently, though, at home we've been dealing with European hornets intent on driving away anything that might try to take over the apples on the Granny Smith tree in the front yard. (Not my house, not my choice of planting area....) Those I cheerfully kill any time they make it through the screens and doors and into the house.

May all your visitors be dragonflies and none of them hornets.
