Thanks for the tip. Sounds scary. It's here in PA, and all the surrounding states, including our favorite camping area, Maryland. Note that the authorities want us to use an "EPA-registered" spray. Hmmm.

The clip is certainly worth a watch.

We did not have any mosquito trouble at the beach in Delaware, but the flies at times were biters.  If the wind came from the west, the biting flies came with it, bleh! and Ouch!  But only really had one day that was truly bad.  And no spray worked on them.  Just had to cover up, or get into the ocean, or the camper.
