What puts it there?

I blame it on the recent infestation of these little bastards…

Apparently most of the bat population has died off in NJ due to white-nose fungus (no, I didn’t make that up lol). Because of that, these little emmereffers are EVERYWHERE! I found a live one in January in a track, couldn’t believe my eyes!

On the same subject, found a relatively large dead fern leaf half-in-half-out of a screen the other day. Could not for the life of me figure out how it got there. Nature works in strange ways

Chris,
I think you may be right. I have seen them lurking around the tracks but I’ve never actually caught one stuffing a piece of grass in there. HaHa

I always thought they were grasshopper nests. One more window cleaning mystery solved. Thanks!

We get mud daubers here, same thing but with mud/dirt. Its a nice upsell to remove the nests, scrub the base clean F 90 works good with a boars hair. I remove the dry, less messy.

I’m ratting you out to PETI (People for the Ethical Treatment of Insects), Dave.

Good find, I have always wondered what those were…I only see them on the types of screens that move up and down and are removable from the outside. I am a huge pansy around bees/wasps…turns out I’ve been essentially grabbing their eggs with my fingers. Very interesting.
