My 245 has been sitting for the last few weeks due to travel and just generally being too busy to drive it.

I went to use it yesterday and heard that "dry leaf" crunch sound when opening the driver's door that I've heard so many times before at the junkyards. Sure enough there was a little paper wasp nest starting in the door jamb. Fortunately they weren't around! But then I noticed wasps around the outside passenger side door jamb. Another nest was on that side. I checked the tailgate and rear doors and didn't see anything else. I dislodged the front passenger side nest and crushed it, but before I could get back around to the driver's side I saw a couple wasps go in, and then I saw a couple go into the cowl vent. At that point I just left the area as it seemed they were responding to an alarm!

So I'm pretty sure I have a wasp nest in the cowl vent too. I can handle the driver's door jamb easy enough, but what to do about the cowl? I can't even get close enough to see if it's visible, and won't spraying poison risk getting it into the ventilation system? There could be nests in the rockers even, no?

I'm thinking I should just get a hose and flush the cowl out with water. I cleaned the rockers out really well about 1.5 years ago and have snow caps so they shouldn't be too clogged with leaves/debris.

Any other ideas?
