Mud Daubers/Hornets/Wasps

I have lived in the county for most of my life. Insects, rodents and snakes live here also.

I do what I do for a living, they do what they do for a living; which includes taking advantage of my unintended hospitality by finding nice secure nesting places in my equipment.

I once removes a furnace that didn't work from a TT that I owned. Dumped a whole coffee can full of mud dauber nests out of it. There is more in there then you think.

Insects are "hard wired," They have only instinct to get through the life cycle. There s no decision making process involved in nest location. Knock down a nest and it is very likely that they will return and restart a new one in the exact same spot. That is because they only have millions of years of instinct implanted in their tiny brains, and they will build where this instinct tells them to.

So that is the reason why. Don't believe it? Then disregard my 35 years in the insect business and Google it.


I will leave control of same to others.

I believe you. I'm just not sure that human beings are that much better. lol

LOL. I agree. Sometimes the insects ARE better. :)

You can buy commercial wasp/hornet killer at Lowes and HD that sprays around 10' or more and kills them instantly. I've used it for years at home and there is no chance that anything hit with that spray will do anything but die immediately.

Thanks to all for the inputs - it was about what I thought. Since I always park the TT in the same place; they are going to come back and nest in the same places. For me, the "scary part" is that they next under the roof vents. That means getting on the roof taking ofc the vent cover to clear them out and trying to safely get down off the roof before any angry escapees come after me.

This works for me - get a flea collar for a dog and cut it into pieces. Put the pieces in those places where you don't want insects.

For the ones up top, buy the hornet/wasp spray that shoots 20 feet.

Fairly stationary object, so if you park it they will come! :B

I have found nests inside the rear bumper (the caps have holes) on the back side of the tires (exciting when you remove the tire covers), and the occasional scorpion hanging out in the wheel chocks.

The gas appliance vent screens are the definitive fix for critters in the vents. Except when we're using the trailer, I always keep the cover on the AC and have never had an insect issue with it. Now, if someone finds a cure for the 'propane spiders'.............:W

Watch out for this instant killing type spray around propane, it is quite flammable, I think it actually contains gasoline!

I used it around the fridge vent to get rid of a hornets nest once on an older TT. I thoughts I cleaned up the spray enough, but some remained in the drain cupholder for the fridge. Later that day I started the fridge on propane, and WHOMP, it was on fire :E Luckily I was with the trailer at the time when I noticed the black smoke coming from the fridge vent on the rough. Thankfully the only damage was from me emptying the fire extinguisher on the fridge and wrecking the ignitor...:S

we were told when we bought one of our trailers in the past.. buy a large flea collar for a dog,, cut it half,, put half in the water haater area and the other half behind the fridge outside.. have never had any probs with yellow jackets or hornets. we have screen on the heater
