Believe it or not, this works.

I have adapted it to mount on my mower. The key is making sure that the trap is higher than your head when you are seated. I sometimes just drive around and watch the little @#$% land on it. It gives me great pleasure.

I think Adrian would look quite sporty wearing the hat/trap apparatus while cycling through the woods.

Yes, and I will be singing "Whip It" as I ride!

The things on I learn on this forum...

I don't have a hat. I made something similar to the ones on the sideview mirrors. I mounted it on a pole and have a little box for the pole to sit in. I have to take it out when I go under a tree. It is not unusual to end up with 70-100 deerflies stuck to the trap after a 2 hour mowing session.

I wonder if a patch of doublesided carpet tape on the back of my hat would look too "tacky".

You're already riding a lawn mower. I wouldn't worry about your appearance.

Rob's riding the mower, I'm on my bike.

Carpet tape...tacky...git it?

I hope you guys don't call PITA on me for slaughtering Deerflies....

Great, so this guy is a member of PITA too?

Well, I guess you guys are not vegans, since you spell PETA as something one can eat.

Here's how I remember: P-E-T-A
People Eating Tasty Animals

Robert De Niro as 'Rob' in the "Deer Fly Hunter".

PETA's a bunch of vandals, thieves, and animal murderers. Hypocritical motherf*&!ers.

No... P-I-T-A
