Insects and debris entering your RV's vent openings can cause real problems. Wasps, mud daubers, and spiders are known to build nests inside furnace burner tubes and water heater flue passages during storage, which can block airflow and prevent proper ignition when you start the season back up.

Insect screens fit over the exterior vent openings of furnaces, water heaters, refrigerator vents, and roof vents, blocking pests while still allowing adequate airflow for your appliances to operate correctly. Our selection covers screens sized for furnace and water heater openings, absorption refrigerator side vents, roof vents, and range hood exhausts.

Measure your exterior vent opening before ordering. Refrigerator vent screens in particular can vary between Dometic and Norcold models, so confirming your specific model before purchasing is worth the extra step.

What do RV insect screens protect?

RV insect screens cover the external openings of furnaces, water heaters, refrigerator vents, and roof vents to keep wasps, mud daubers, spiders, and rodents out of the burner tubes and flue passages. Blocked vents are a leading cause of furnace lockouts and water heater no-light conditions, so a fitted screen behind the access door is cheap insurance. Pair them with maintenance from our RV Winterizing Kits collection before storage season.

How do I find the right bug screen for my RV furnace?

Match the screen to the furnace brand and BTU rating, Suburban, Atwood, and Dometic furnaces use different vent geometries, and the screen must clear the burner intake without restricting airflow. Check the model tag inside the access door for the part number, then confirm the screen is listed as compatible. If the furnace shares a sidewall with the water heater, you may also want a matching water heater screen.

Will insect screens fit refrigerator and roof vents too?

Yes. This collection includes screens sized for absorption refrigerator side vents, roof vents, and range hood exhausts in addition to furnace and water heater openings. Measure the exterior vent opening before ordering, refrigerator vents in particular vary by Dometic and Norcold model. For related vent hardware, see our Ventline Vent Essential Accessories collection.

How often should RV bug screens be inspected or replaced?

Inspect screens at the start of each camping season and after extended storage. Stainless mesh screens typically last several seasons, but wasp nests, soot buildup from the furnace burner, and UV exposure can degrade the wire over time. Clean with a soft brush and compressed air, and replace any screen with broken strands or visible gaps. Need help confirming fitment? Text or call 817-984-1852.

Does United RV Parts offer free shipping on insect screens?

Yes, orders over $100 ship free. Most insect screens are small, lightweight items that ship via standard parcel, so you can combine them with other small parts like adapters or hardware to hit the threshold. See our RV Plug Adapters collection for common add-on items.
