Mesh screen to keep mud dobbers out?

[coltsdad]

Since we are not camping in the few weeks. I went out in the trailer and was messing around this afternoon. Turned the living room ac on and all was good. Turned the bedroom ac on and I thought my son had hit the trailer with his four-wheeler. Looked around found the noise and vibration was from the bedroom ac unit. After some searching I got on the roof and pulled the cover to find a huge mud dobber nest on the condenser fan, I removed it and all was good.

I put on the screens for the water heater and refrigerator. Have any of you put screens on the ac units and if so what did you use?

You must live here in Jacksonville.lol I'd like to see some answers here myself. Just cleaned our rig for long trip and found 2 on our rig. Doesn't take but a small slit for them to get in.
