Bug Insulation

I was always worried about bugs getting into the back of my motorhome’s refrigerator through the exterior vent when the motorhome was in storage. To put my mind at ease, I bought some inexpensive pipe insulation and cut strips to length, and pressed them into the cover vents. Now I don’t worry about the bugs – but I do have to remember to remove them before turning on the fridge.

  1. It would have been far simpler to just go to your local Home Depot, Lowes, Walmart or hardware store and buy some window screen. You can fasten it to the inside of the cowl with tape. It keeps the bugs out, doesn’t restrict air flow, and you don’t have to remember to remove it.

    My motor home has an underfloor furnace with vents to the interior and to the utility compartment. The Utility compartment is open to the outside. Bugs were getting in, and even a mouse. Screen closed off all these openings. It doesn’t restrict the airflow and keeps pest out.
