Got curious---- http://www.vdacs.virginia.gov/plant&pest/fireant.shtmlAre you sure they were fire ants? I lived in Vidalia, Georgia in the 1980s and we had lots of fire ants there. From what I understood then is that fire ants had not migrated into Virgina or North Carolina because the winters were too cold for them. Since it has been more than a few years since the 1980s, your post sparked my curiosity. Fire ants are brutal and can be very dangerous. They will pour out of a nest and crawl onto an interloper and all begin to sting at once. From what I understand, the toxin in the fire ant sting is similar to the brown recluse spider in that it kills flesh on contact.
We have many ant varieties in Virginia but as I noted above, I have never heard of fire ants in Virginia. BTW, I live all the way in the top of Virginia where Maryland & West Virginia come together with Virginia and there are absolutely no fire ants up here.![]()
