I buy 55 gallon drum liners that are used for all kinds of uses including
lining drums for storing food grade products, so they do not have any
pesticides in them. I used 50 gal in the calcs because I was rounding down
for back of envelope calculations.
I do not use many pesticides around here. I even have my wife picking up
spiders from inside the house and putting them outside. Thanks for your
concern.
