black snakes beneath house siding
Snakes are great for our gardens and landscapes and should be preserved if possible. Understandably, you don't want them in your home however.
It is possible that this baby snake is accessing your basement area, and if he is, it is to find food, usually in the form of rodents. (And rodents chew and damage things)
Try going into your basement area during the day and turn off the lights. Do you see any light seepage from outdoors? Any cracks can allow wildlife and insect entry.
Here's what to do: On the off chance that the snake is already in there, we'd suggest laying down a damp towel on the floor. In the morning, place a trash can over the towel, slide a flat, thin board or something similar between the floor and the can, and flip the whole thing over (covered) and take it outside to set it loose.
That done, you should caulk or otherwise fill-in the cracks or holes between the brick and the siding.
