Question:They are all over my house. It seems like there is millions of them.
I have a picture, that I'll post the link below.
When you look at the picture, that's just one section.
They are like that all over my house.
It's really gross.

Answers:
Try spraying them off with a garden hose with a spray attachment for extra force. Once you have them on the ground and off the house, you can zap them with Raid which works better than the sprays you find at garden centers for these kind of worms. Another option would be to use a shop vac to pick them up off the walls. Put a rag soaked with Raid into the shop vac.
