Gotta admit watching parasites flee a dead carcass creeps me out.
I shot a gray fox while scouting one morning last year. It was before full sunrise and I had a lot of miles to cover, so I stuck the fox in the crotch of a juniper and left it for the return hike.
As luck would have it, I took another route and did not get back to the fox until about 28 hours after its death.
Figured the fleas would be long gone. I figured wrong. Fleas were still jumping out when I skinned it.
Some old trappers put critters into a bag with spray. I would use 7 dust, but when I tried it on my cat, it discolored the fur a bit
Few things are as funny as a cat leaping about in response to the death throes of a hundred fleas ...
But afterward, she was happy.
