THERE ARE ANTS IN MY RV!
If you are RVing anywhere in nature, you're going to find ants. Bless their tiny little bodies that work so hard for their queen, but they cannot be tolerated in your RV.
Ants send out scouts who scour the area, looking for suitable food and water sources. If one crawls up your RV tire, water hose, power cable, etc and eventually finds something inside your rig, he leaves a little smell trail of pheromones. SaveSave
