The red fire ant was accidentally introduced into the United States in 1929, when a cargo ship that had used soil as ballast arrived in Mobile, Alabama from South America. (Thanks a lot!) But South Americans don't have nearly the problem that the United States does. They only have 20% as many fireants as we do, probably because North America lacks the natural enemies of the pesky critters.With the cold weather in the Pacific Northwest, you shouldn't have to worry!
These guys are aggressive! They initially spread throughout Alabama and Florida, but it didn't take them long to invade twelve of our southeastern states and Puerto Rico. In recent years, the fireant has spread as far west as California and as far north as Kansas and Maryland. Although fireants keep marching farther and farther, northerners don't have to loose sleep over it because researches predict that they will not be able to survive in areas where soil temperatures drop to near freezing for more than 2 to 3 weeks.
Fire ants safely under control, we'll be working on pruning and moving palm trees this weekend- hopefully we won't kill them in the process. I'll keep you posted.
Just be glad you don't have these in your yard!

Yikes! I'm glad we don't have those either. I haven't been bitten yet, but I understand these fireants are pretty painful - hopefully I'll never know!
ReplyDeleteI wonder if fireants are like red ants. I used to get bitten by red ants on Guam. And it hurts!
