We've got plenty more around here if you want me to send you some.
Seriously Connie and I have been killing them by the boatload. The hand held bug zappers are knocking the hell out of them. Literally. I think Connie actually enjoys the battle. In the past we always felt so helpless around here when they arrived each year, but this year we feel like we are able to effectively fight back and fight back HARD. I do have to admit that I am beginning to get sore wrists from waving the things around, but I guess that is being countered by the great cardio workout we get as a bonus.
Yeah a few will still land a bite now and again, and it still hurts, but it is darn satisfying when we see the flash of light on the bug zapper that indicates that there is one less yellow fly in the world to attack us. Kind of makes the bites bearable somewhat.
And the mosquito magnets are sucking down some too. Too add to the mayhem, I just recently purchased some spray on Tangle Foot adhesive that I am going to be apply to plant nursery buckets and hang them from trees using fishing line. Hopefully the lizards won't get on them, and I am using very fine line with the hopes that they won't be able to crawl down to the buckets.
So perhaps the one you found is one that realized that being around the Zuchowski place isn't a real healthy place to be if your are a yellow fly.
Anyway, for each yellow fly we kill this year, that means even less (hopefully) to have to deal with in subsequent generations. Heck, I would be all for extinction for those damn monsters. If it were only within my power....
