I’m a very light sleeper, so I have blackout stickers on my bedroom window. (They’re vinyl sheets that stick to the inside of the window with water.) I’ve used these most of my life with no issue. Well, I moved from the city and my new place is in a wooded area. I’m hearing birds and squirrels bonk into the window because they think it’s a little cave or something. With the heatwave it’s now multiple times a DAY. I opened my window today and there’s actually a small pile of dead bodies on the ground. I feel awful.
Is there anything I could do to help these animals understand my window is a black wall and not a cave?
That’s true, so closely spaced markings are recommended. I had the same problem and this dotted tape solved it completely. Personally, I didn’t want clip art graphics on my windows, and I like the fact that the dotted tape minimizes interference with my view outside. You can find more information on other strategies here though (like drawing deterrent patterns with bar soap).
*Two inch spacing worked for me, but you might need to make it denser depending on the species you’re accidentally luring
