Remember that as repulsive as snakes & spiders are, they control the pests you do not want in your home like rats, mice, ants and other vermin. Most people would like to keep them outside.
Basements are one of the most common problem areas for snake infestations. When the ground shifts from frequent thawing and freezing, foundations on builds will shift and crack. These cracks are ideal places for snakes to create dens. The gaps along your home’s basement are not the only way for these reptiles to get inside. Snakes can maneuver through holes of many different sizes. Common places for them to enter at ground level are through uneven door jams and through damaged window molding. Before you can hope to get rid of any snakes inside your home, you will need to patch all the openings that might allow them inside the building.
Snakes are not as industrious as other nuisance animals, and will not chew through sealants and other blockades. There is nothing a snake likes more than long grass to hide in along a foundation. If you can keep the grass short, and keep gardens away from the home, snakes will have no cover to shield themselves from predators or the elements.
Snakes do not do any physical harm to the home; they simply live in an existing crack. Unless the serpent has made its way to the interior of the building, consider letting it stay. Snakes keep away rodents and eat insects. Letting a rat into your home will be far more problematic than allowing the snake to stay.

In most of the United States, most commonly encountered snakes that are found around human habitation are non-poisonous, but in the South, West and parts of the East, it is not uncommon to find poisonous snakes around buildings in somewhat sheltered areas (flower gardens, porch overhangs, garages and carports).In one instance, a homeowner living on a wildlife-friendly acreage in Wisconsin regularly found harmless garter snakes in the sump-pump pit of his split-level home. A careful search for their point of entry found an unsealed gap around an incoming water pipe. Once the snake entered the dwelling, it encountered the basement wall in its attempt to find a way out of the building; this of course resulted in it eventually ending up at the partly covered sump pit, a perfect snake trap.
You want to keep your sump pit covered. Unfortunately Basement DefenderTM does not have a snake alert, but is something we could add as a feature down the road?
