As promised, the mud dauber nests that came out of my Ford. Some were in the heater plenum, some under the dash up high. Like how one was wrapped around a wire.
Reminds me of having to make a trip into town from a little wrecking yard in the next town over from where I live to get wasp/yellow jacket spray as they were very serous about guarding the AD truck I needed a part out of.
I got an SBC bare block from a guy one time and every hole had a mud dauber nest in it! It took me forever to get it all cleaned out.
Assume any carb thats been sitting on the garage shelf has holes filled with muddaubers, them things can breathe anything. I once did an edelbrock that had the fuel crossover hole plugged with about a dozen of them, one would go in to build a nest while another was doing the same blocking him in.
Another reason to like Canada. We don't have bugs like mud daubers Every time I'm in Texas I am always amazed with the hordes of different bugs that I have never seen before.
No telling how many of those dirt clumps I knocked off of my car when I started working on it, never thought about them being a collectible. More of a nuisance than anything else. Around here, if you store anything with a hole in it like a carb or piece of tubing or hose, you better plug or tape up the end of it or when you do get ready to use it, you'll be digging that crap out with a stiff wire and blowing air through it!
I have never had them build on anything that was greasy or oily. I'm going to spray PB Blaster all over things I want to protect. Results to be posted next winter.
I have hunted up in your neck of the woods & I'll take the mud daubers any day. Those black flying things are miserable. DEET is your friend there.
I'll tell you what, I will compare the Canadian list of nasty biting or stinging insects to the Texas or southern US list any day. The US list will be twice as long
Hey Blue...Over here in Ontariareaireo we have those suckers. They seem to be more of an old building house thing though. I have 1 Dauber nest in my collection of interesting things. I've never been bothered by them. Yellow Jackets and hornets that's a different story. Reading some of these bug stories creeps a man out.
