Snakes at the zoo: super cool. Snakes around or (gasp!) in your house: NO. NO. NOOOO. Snakes might be the worst intruder (or is it bats?), but any unwanted rodent or animal in your home is gross. Your best offense is defense. But if they break through, call a professional exterminator.

• Cover holes more than a quarter of an inch wide (snakes don’t need much). Check behind gutters and roof flashing.
• Trim trees to keep pesky animals, such as squirrels, from getting on your roof and into your attic. Keep branches at least eight feet from your house.
• Eliminate any food sources — like a garbage bin with an askew lid — that might tempt a scavenging pest. The closer they are to your house, the more likely they are to find a way in.
• Get rid of yard debris, such as piles of leaves and twigs, and mow frequently to eliminate hiding spots.
