“I found this tiny worm on my main floor hardwood last night”, writes Sally about the brown, striped critter pictured below. “My main floor is entirely hardwood, but it was at the base of my stairs and my second floor is all pretty old carpet. We have two dogs. Earlier this year, I found one of these in the dogs’ toy bin, and a couple underneath a plush dog bed, which I immediately disposed of. Can you please provide your best guess as to what it is? I’m located in Oakville, Ontario, Canada. Thank you in advance. From a worm newbie.”

“This morning I found a live caterpillar or worm”, states this reader in California, who attached a photo of a large, brown caterpillar. She stated that it “looked like the Noctua pronuba caterpillar burrowing into the fleece fiber of my dog’s bed.”
