What's the strangest/worst thing you've seen infesting your property?

[Joseph Weisenbloom]

I know there are the standard rats, mice, termites, bedbugs, fleas but anything out of the ordinary you have found? Reason I ask is I am currently dealing with some birds that think they can just make nests in every nook and cranny of my siding/roof. Birds are just rats with wings as far as I am concerned!!

P.S. Bonus points if you have a solution to my bird problem!!
