I have been meaning to put this photo up for some time as I found this about a month ago. Right before Jack and I went out to Arizona, I noticed this yellow jacket nest in the ground one day as we were experimenting with putting up his tent. It seemed large as there were lots of the little buggers going in and out of the hole but thankfully, they did not bother us. I made a mental note to dispose of them when we got back because they had built right near the clothes line and it would be my luck to get them riled up just hanging out clothes. Well, after we got back I was out doing a little yard work one day and noticed this big hole in the ground. Upon investigation I surmised that armadillos had dug the nest up and eaten most of it. I don't know of any other critter that could have managed that without being stung so bad they would have run away. I had noticed in the previous months that armadillos had been digging here and there in the yard but I don't bother them. They are only after grubs, which turn into Japanese beetles among other things, so I let them have at it. Well, apparently they like grubs of all kinds because they had completely decimated this yellow jacket nest. I found pieces of it strewn all over the yard. I guess they picked it apart to get out the larvae. There were also lots of dead adult yellowjackets lying in the hole.
I know many people despise the ol' dillers but I don't mind them; same with the moles that lots of people drive themselves crazy trying to run off. They do make little holes or mounds here and there but I've never had them destroy many plants like a lot of people claim they do. An occasional veggie victim here and there but to me, the pests they eat are worth a few uprooted plants on a rare occasion. Most everyone else around me has horrible problems with Japanese beetles and such but I rarely see more than a handful around my house and I can pick them off by hand and squash them. And now that I know the 'dillers eat yellowjacket nests, well, they are greatly welcome to root around a little. I had a heckuva time trying to eradicate one nest last year the the bees had dug right in the middle of a trail I frequent to the spring. I tried several bombs and sprays and don't know that I really succeeded but these ol' possums on a half shell made short work of them it seems! Saves me money and aggravation. The only thing better would be if they would eat fire ants too! I think Nature itself will often provide for it's own control and management if we would just let it, no chemicals needed.
