Palmetto Bugs…oh my ummmmmm well the south has been pondering that question for quite some time now and they have yet to reach a solution. Palmetto bugs are a variety of cockroach and as such, they will be here long after we’re gone. They are perfectly adapted for survival hence why we have fossils of them dating back to the days of dinosaurs and their body plan is almost wholly unchanged since then. You just don’t mess with perfection. Among their claims to fame are their abilities to flatten their bodies to avoid being crushed when stepped on, they’re well able to regrow limbs as juveniles, their ability to derive sustenance from nearly any organic food source from decomposing plant material to glue, wallpaper and grease, they’re able to recycle their urine indefinitely to avoid needing a source of water in most instances, and they can survive for days without a head as a result of their nervous system not being centralized. They can also survive some pretty lethal doses of radiation but it’s been proven that there are many insects that have this ability so it’s really not as special as we once thought.
The bottom line here is that you or the south really wont win this fight so the best you can do is reduce casualties. Because of the warmer temperatures in the south, species of cockroaches that can’t fly in the north are able to warm their flight muscles consistently enough to sustain flight. They typically fly at night and are attracted to lights so don’t leave the porch light on and don’t leave unscreened windows open. In addition, it’s generally a good idea to avoid leaving food crumbs around after dinner as that will draw them indoors. Aside from that, I think you should try to convince them that you’re on their side as they may be our overlords one day. May I suggest an offering of glue?
