The first time we camped in our TT we became overwhelmed with gnats and mosquitos. Decided I needed to try something to combat the infestation inside the trailer.
I remembered I saw a blue light gadget with a fan that captured insects and killed them by dehydrating them. I went back to costco but alas they had Christmas stuff out and the outdoor equipment was gone. So I decided to hit Amazon and see what I could find. Well I found
https://www.amazon.com/gp/aw/d/B07CZ...op_mb_pd_title What a great little gadget. Sadly it's not bright enough to get them during the evening with other lights on, but when we head to bed the bugs leave the bedroom area and head to the blue light. It captures gnats, mosquitos and moths. Sadly, flies seem immune but it works great for everything else. So if anyone is looking for something like this I can recommend the above.
The only cons are the flies and it doesn't come with a 120V adapter plugin for the USB it needs. Luckily I have a ton of those and can also use a battery backup so it doesn't need the plug in.
Just an idea for anyone that needs something like this.
