I wouldn't soak them for 2 or three days. The longer you soak them, the blander they taste. Soak them in salt water for a couple hours then rinse good under the faucet. I find a lot of these little bugs too. Don't think a few will hurt you. Never has hurt me.
They are just springtails, not fleas. They are in almost all mushroom types. Just dip you morels in warm salt water for a minute or so before cooking and rinse them out. They will definately not hurt you. Rinsing them will also help take out the maggots!
Yeh I hate those little bugs (Not fleas) also, but you can't avoid a few of them I guess. I am sure we have all eaten them and still live on...lol. I just justify that by the time we fry the heck out of them they disappear into nothing since they are so small to begin with! But, I usually rinse my mushrooms (cut in half first) in 3 stages of salt water. Then I rinse them individually under the sink. It is a tedious process I guess, but that is what I do to get most of them out. Never saw a maggot in one! lol
have never found springtails on a morel here in wis. just lots of taterbugs, and slugs. have found them on the hen of the woods though. i'll have to keep an eye out for them this year.
