At home, we have about 30 blackberry plants. We have really enjoyed picking and eating them right off the plant -- they are wonderful and sweet. But over the last 2 weeks, the June bugs and Japanese beetles have also been enjoying their sweetness.
I have found that our small black berry patch is the choice home for many, many mosquitoes and June bugs. As I go pick in the 90 degree weather, I wear long sleeves and long pants to deter mosquitoes -- but they usually find my uncovered neck and face to bite.
And the June bugs -- well, there's nothing you can wear to deter them. Maybe a suit of armor would be appropriate. They come flying out in their addled way, usually bumping into something (my head mostly). If one lands on the ground, the foot comes down on it. And you don't have to be quick, the poor lumbering souls are easy prey for the foot thing.
