We have a problem with tiny black spots the size of the head of a pin on our windows and door on front of our house. Do you know what is causing this and
do you have a spray that will take care of the problem?
There are several things this could be. The first thing that pops to mind is a mold or fungus. Treat with some MOLD/FUNGUS KILLER and if that’s what you have growing, it will quickly die off and fall off to the yard below.
The second thing that comes to mind would be spider droppings. If you’ve got lots of spiders up around the soffits and gutters, no doubt their droppings can be a problem anywhere below a spider nest. Here’s some more information on this kind of problem:
If you think the spots are from spiders, you’ll need to do some outside spider treatments as suggested in this article:
The third thing I that pops into my mind is some kind of insect. Are the spots moving or appear alive? Get close to one and see. If after a close inspection you decide it’s alive and moving, collect some samples and get them identified by a local pest control service or extension agent. Once we know what you’ve got, I’m sure we’ll have some suggestions on how to get rid of them.
