Hello, I am a newbie. We just purchased our Casita last month (Mar).
I was surfing on this website and found one man's collection of mods he'd done to his Casita. The one that really caught my eye was that of a screen that he put over the two
circular vents on the outside and on the right (door) side of the trailer. I believe they're air vents for the propane furnace, because the brand name Suburban is on the cover plate.
He'd installed a screen over the vents to keep wasps from entering the vents and building nests.
I have three or four species of wasps in my area, and all of them probably would adore building a nest in the vents. the idea of having a swarm of yellow jackets in my trailer is not something I want to contemplate, never mind suffer.

I would like to install a screen to keep them out.
HOwever, I have no idea if the man who made the mods made the screen himself, and I cannot find that specific post.
Is the screen an aftermarket item? Do I have to remove the metal frame from the trailer (which involves breaking the pop rivets, I think).
Is there a problem with it impeding the air flow into and out of the furnace? If I used aluminum screening, would the screen burn up?

I think the man who posted the photos was named Fred, but I may be wrong. Whatever, if anyone out there can give me advice on this, I would be most appreciative.
Thank you!

Bugged?

I was warned about the dreaded Wasp Nest the night after I bought my Casita in 2007. I dashed to the little store at the RV Park and purchased the recommended screen to afix to the outside of my heater vent. It evidently worked as I have noticed no wasps. That particular screen disappeared, as did the replacement screen I bought for nearly $20. I currently use a piece of duct tape over the vent. I have been careful to remove the tape when the heater is in use. I don't know if my expensive little external screens bounced off or were aided in their departure by someone who felt they needed them more than I. As I pointed out to my physician "just because I'm a hypochondriac doesn't meant I'm NOT sick."

The excellent screen placed between the vent cover and the side of the Casita seems to be an excellent, and well documented modification. Once I overcome my Pop Rivet Reluctance (related, I suspect, to my fear of drilling holes in the exterior of the Casita) I will probably attempt to apply such a modification. Until then, I'm sticking (ar, ar) with my duct tape solution.

In addition to the heater vents there are several places where critters (wasps, mud daubers, etal) choose to set up housekeeping. Several members have documented their various solutions - here is a link to pictures of mine.

A couple of stainless steel sink strainers work good. Available at the dollar stores. Also need 2 small springs long enough to affix the screens. Or use #26 SST wire. I really didn't want to pay $14.95.

The pix of the vents with the flat piece of screen looks good too. Trim to fit, use the SST wire to fasten. Non-insulated #26 or 24 copper could work to fasten, might eventually burn off.
