bring Boric acid to spread around the parts of your coach that touch the ground. Or, diatomaceous earth did a good job protecting from ants.
The ants are everywhere. Spray all things touching the ground & the outside of your camper! Get Home Defense & Comet & cover the outside of your RV as soon as you arrive!
