Unhappy Why do wasps love furnace intakes ???

After having an RV of some kind for 40 years from truck campers to several motorhomes I never bothered or had a problem with the furnace being occupied by wasps.... until now.

Having installed a new furnace in the twinkie and storing it at my brothers, he's lucky enough to have the little buggers swarming around his new house, they parked their little butts in my furnace.

I saw the little devil go in, I peaked with a flashlight and saw an antenna hanging down, then thumped the side and he popped his head down and looked straight at me, looking like WHAT DO YOU WANT BUDDY.

Even though Suburban doesn't recommend the wire screen covers I bought a set of Camco's today and slapped them on right after one (the only I hope) came out and flew to the woods. As soon as I finished fishing the springs into place he came back 5 minutes later and is persistantly trying to get back inside (not a good sign though).

Any recommendations on how to check for a nest and get it out since it's got a cross plate and the intake goes up? Hate to pull this puppy apart

The problem is that bees and wasps are attracted to the smell of propane. You may have a small leak or when the pilot lite comes on. Had a propane supplier tell me this as he had problems when doing refills.

I was having the same problem plus frig and hot water compartment. Solution was to put a dog flea collar in the outside compartment plus one in the furnace intake/output.

Found a twenty room wasp condo in battery compartment. Foreclosure was swift. Know battery has to have air, but thinking screens are going to be installed.

Why? - For the same reason that fire ants like the power contactor in condenser units of home air conditioning systems - though neither specie has revealed the reason to us humans.

Wasps are especially devious bastards though - some of them built a condo in the fresh air inlet for the cabin of my dad's Cessna 172 - he didn't find out about them until he got to about 3000 ' and then opened the vent for some fresh air.

In a way you are lucky, you spotted it before major problem, you or camper.
My worst experience was at top of stepladder when they didn't like my pounding close to nest.
They have a kack of setting up housekeeping in any place undisturbed for a day, I have found them
under flap of carboard box, under rim of boat, in vent pipe for fuel tank, under eaves, anything I build is better than what nature provides. :-)

have you noticed....?

With all those wasps (and the hated dirt dauber kin) you do not have a spider, or other bug, problem. They end up as lunch for the wasps. I guess its a trade off....
