Bug Spray SPF50

Back in the winter, I was diagnosed with three outbreaks of melanoma that were removed with something like a post hole digger, then the skin pulled together over the post hole and stitched together\, leaving scars that might suggest I'd fought Errol Flynn with swords in an Irish castle.  The doctor who operated that post hole digger and subsequently darned me up also suggested that I use a sun screen when I'm going to be outside.  I recently bought a tube of 50 SPF and have it on the shelf in my shop which is down in the barn.

Our house is nestled in the woods adjacent to a wee lake and by early May, we must also begin protecting ourselves from flying critters of all sorts that delight in attacking exposed skin.

Earlier this afternoon, I was going outside to work and asked the State Peach of the Peach State which I should apply first, the sunblock or the insect repellent.  She advised spraying the repellent on after first smearing myself with the sunblock.  I grabbed a new can of Deep Woods and went down to the shop where I smeared my skin with a thick layer of something that looks like goose grease, then sprayed a on goodly amount of repellent.

I had just a small patch of lawn that I'd not cut last week, so in a short time I was done and back at the barn.  About the same time I got off my lawnmower, I felt the beginning itch of a bug bite, right at my knee.  Within ten minutes or so, it had become a full-fledged pricking irritation.

Now I know I sprayed that area and the bug spray I used has been effective in the past, so I must assume that I was attacked in the 40 meters or so between the house and the barn.  Do you suppose the insect knew that I'd be spraying myself as soon as I got to the barn and decided to launch a preemptive attack before I could defend myself, or was it just seeing me as a target of opportunity?

I wonder when the manufacturers of sun screen and insect repellent will create a new product to take on both issues.
