I don’t know about that...really I don’t know. I have read where large tract treatment can be done successfully, but at what cost?
Yes, you treat one or more mounds, and the SOBs pop up ten feet away with a new mound. Seems like that is more apt to happen after a rain.
At best all I’ve done is suppress their activity to some extent. I have a pic of my foot where the damned things got on me last summer. Red blisters and pustules everywhere. Nice imported pest we have here. I was surprised to learn that fire ants in the south are a relatively recent problem...1954 or something?
Bee got in my sandal last summer, stung me, I’m mildly allergic to them, foot started swelling and lost some feeling, THEN managed to stand on fire ant mound and got bit many times before I noticed them, foot then was so swollen I could not wear a shoe on it the next day. Might have been some alcohol involved.
