I'm curious if this is just a problem with casement windows in general. About 25 years ago we built a new addition plus had the windows in 2 bedrooms replaced with Andersen casement windows. We used casement windows because that's what was there previously, plus they seemed to have their pluses. But......I can't believe how many bugs (especially asian lady bugs) get in there and hibernate, or die underneath the window frame/above it/beside it. And that's not even the windows that I ever open in the summer! I just cleaned 2 that hadn't even been opened in years, and there were tons of live, but mostly dead ladybirds. YUK. I'm tired of this build-up of bugs in there over winter. The problem with the ones I open in the summer is that the screen, even though it's there, it's positioned so that part of the inside wood is exposed and also a space below the inside frame. Kind of a weird setup. Anyhow.......is this pretty "normal" for casement windows?

Thanks!
