Just stayed at Lake Skinner near Temecula, CA. Woke up in the morning and the whole inside of the Mother Ship was crawling with ants. DW was totally freaked. She wants a professional exterminator...
Common occurrence here. We were invaded this past weekend. We use Home Defense around electric cord, hoses, tires, etc. DW doesn't want to use it inside so we spray them with Windex which kills them on contact. Many use Borax powder to around everything on outside to form a barrier. If you are one a wooded site, look for limbs touching RV that can also be a path for them.
