Properly used permethrin works amazing. I almost gave up morel hunting due to ticks. With Properly treated clothing I watch them jump off of me.
Can I come watch the ticks jump off? Has nothing to do with your Morel spot, at all. Zero.
for cripe sakes just pull the lil critters off. plenty of them around here(if you are actually out in woods). always has been always will be. last thing i want to think on now is a new vaccine for anything! im with ya on that lowacord. cant be trusted but can any these days? seems the medicine world has gone to the evil greenbacks side.
