I laid in my Blackbird last weekend and watched the abomination that is the scottish midge, pull itself through the mesh in the netting and into my living space. I had to resort to wearing a headnet at the same time until I could get off to sleep. During the night the wind picked up and they cleared off so I could take off the headnet and sleep in comfort.
I've never seen them do this before but it seemed they were making a bee line for where the net that was in contact with the ridgeline. I sat and watched them just a few inches from my face and they were literally dragging themselves through the tiny holes, The scottish midge is a relentless creature and they're drawn by the heat and carbon dioxide from your breath, once they'd locked onto my tarp and hammock they were not stopping until they got in.
Anyway that's about as bad as we get it over here, nothing that bites your face off in your sleep or things that hide in bushes and hiss at you, but it's still an annoyance all the same.
So my question is will 80% deet spray wreck the nylon of my BB netting ? I'm so tempted to try it but I'd hate to see if disintegrate in front of my eyes.
