Hi Everyone. I have a question about strange white spots and smears appearing on my furniture. The pest control guy said it was "definitely" spider droppings. The house is over 100 years old and we do get quite a few spiders hanging out in ceiling corners, etc. They come in mostly, I'm guessing, through the cracks at the top of our windows (windows being re-roped this summer so that they can finally be closed). I can fairly easily wipe them away, but then they show up again. Just wondering if anyone else concurs that they are spider droppings and/or has experienced this same little phenomenon? Thank you.
