Bye bye to the INVASION CARAVAN.
#21. Those little red jungle ants in Guatemala (Peten) are nasty critters. I brushed against a palm fond plant and ended up with scores on my legs and thighs. Dropped trowel right in the middle of the jungle to swat them off.
Formic Acid, even in small amounts, is Formidable, esp. when scores of ants are feasting on your butt!
