The Scotland expe sound terrific! Can't wait to see the TR.
I spray our screens from the outside of camper (windows open) with old paint throw cloth on the counter and dining table (no open food around). I also open the screen door and spray through from the outside of camper. A quick blast onto hatch screens (with hatch open) will do. I exit the camper, and let the overspray drift out of camper. I give our camper about 3~4 hours before re-entering it (all windows open). I tend to be cautious, and use an N95 mask when applying this.
Anyone using any insecticide shouldn't do so if they are allergic or have reactions to said. This and my Posts are not an endorsement to use repellent or insecticide of any kind. The onus is on the user to do his/her own due diligence before using any repellent/insecticides.
