We have lots of hornets but I have not heard them called mud daubers or seen them build nests in places like that. Thanks for explanning. BobThe heat exchanger in my furnace was clogged with mud nests. Hornets/mud daubers often crawl into the exhaust...
Excuse my ignorants, But what is that in the picture of the furnace? Bob RT 03C/190PAnd for what I did today, I cleaned these little ****ers out of my furnace. Hoping to get some heat tonight!
