Snakes in the Basement
Cool, dry basements can make great homes for wandering snakes. They can find food in basements if the home has a rodent or bird problem in the way of rats and bird eggs. Snakes are pretty smart creatures and will usually only go where they are sure there is food. If you have snakes in the basement, it's because you have another wildlife control issue that needs to be addressed.
Get Rid of the Snake Food
If you routinely see snakes in your basement, it's because you have another problem to deal with. Luckily, birds and rodents are easy to evice from the basement in most cases. Wildlife removal specialists can usually provide full service exclusion and take care of mutiple problems when they remove your snake or snakes. Rat traps that snap and instantly kill are a good way to remove rats. Birds do not ordinarily seek subterranean lodging, but it is not unheard of. Use exclusion netting to funnel the birds through a basement window or cellar entrance, and allow the snakes to escape as well as they find a new source of food.
Repairing Damage to Your Basement
Heavy rains, snow, and wildlife can cause damage to basement entrances, leaving your cellar space vulnerable to the tenancy of nuisance wildlife creatures. Since they're incapapble of paying rent and using toilets, you should evict them immediately–not to mention the fact that most wildlife or their feces can carry diseases and bacteria that are harmful to humans. Repair this damage and seal up cracks with expandable polyurethane foam to prevent snakes from slithering in.
Exclusion Techniques for the Yard
Snakes didn't teleport into your basement, so there's likely a reason that they were in your yard in the first place. Trim down high grasses, remove piled trimmed brush, and secure woodpiles inside a screened enclosure. All of these make great hideaways for snakes and other wildlife that they feed on. Keep your yard in good order and organized to prevent snakes from moving in and giving you and your family cause for concern.
