I guess that would be the reason as to why you shot down my idea to use blood worms instead of fertalizer.... haha!They aren't the only allergy I have lmao. Also allergic to cats, dogs, pollen, blood worms (yes!) and mold (which means I am SCREWED no matter what season it is!) They make my mouth and lips pretty itchy (and so does lobster even more so, but oddly enough crayfish and crab do not!) but it's not a big deal, just an annoyance, so I take Benadryl first, pig out, then go to sleep lol.
Blood worms on the other hand almost killed me when I inhaled a little dust when I was crushing them for my plants. Since then I keep an EpiPen in the house.
