...then there's fire ants...
Just before marrying Husband 1.0, he took me to meet his parents in Cottondale, Alabama (pause for effect here...)... and as I was exiting his truck, I stepped right into a mound of those things....



In about two minutes, my right foot was so swollen I couldn't get my Keds off... Holy-moley... those things are nasty.
I should have taken that as an omen.

I'll take chiggers, black flies, and all that over fire ants.
Since then, I've upgraded to Husband 2.0 - the no fire ant model.
