I’ve lived in my current home for 31 years because I like it here but if I ever find a snake in my house I will move.
1. Raptors would fill the air patrolling the cane field for easy pickings from the rodent buffet.
2. Mice robbed of their cover and concealment would make a bee line for them nearest buildings trying to evade the hawks and falcons.
3. Snakes would follow their food into the houses.
Only once saw a venomous snake (pygmy rattler) in my house, but no shortage of king and rat snakes, probably 1-2 x year on average. Having a doggy door probably didn't help.
