We're new RVers' and saw your post about screen rooms, not to dissuade you as we have an R-Pod and love our screen room as we have a 120 lb Chocolate lab and need the extra room BUT I have a home recipe I found on Pintrest this year that I tried on our deck at home that actually worked. Whether it was because it was such a dry year or not ,I don't know, I just found that I could actually sit out and not get eaten alive. I also took it camping and sprayed the common areas between our family sites and it worked there also. I thought I would pass it along.
MOSQUITO REPELLENT: WORKS FOR UP TO 80 DAYS!
1 LARGE BOTTLE MINT FLAVORED MOUTHWASH (18 OZ.)
3 CUPS EPSOM SALTS
3- 12 OZ CANS CHEAP, STALE BEER (LEAVE OPEN OVERNIGHT TO BECOME FLAT)
MIX TOGETHER UNTIL SALT DISSOLVES
PUT IN SPRAY BOTTLES AND SPRAY AROUND PATIO, POOL, PORCH, ETC. THIS WILL NOT HARM PETS, KIDS, OR PLANTS, AND IS GUARANTEED TO LAST UP TO 80 DAYS.
(THIS IS FROM PINTREST 2016 & THE PAUL HARVEY, RADIO…..MANY, MANY YEARS AGO).
Give it a try - Happy Camping - our season is over til next year!
