As you may know, there's controversy surrounding insect pesticide IRL because it tends to poison human bodies that eat it.
Could the same result be expected of yukkuri pesticide? If yukkuris can die of that pesticide, humans eating enough of that could possibly die too.
However, yukkuris are definitely more sensitive than humans - the pesticide may be something similar to capsaicin, which is easily washed off and is generally nonpoisonous to humans.
