Southern Hog-Nosed Snake Control (Heterodon simus)

Believe it or not, snakes can be great to have around. After all, they love to eat rodents! But when their populations become too large, or they move inside our homes, often something must be done. Here’s what you need to know when dealing with a possible southern hog-nosed snake on your property.
You’ll find these snakes in eastern North Carolina, south through Florida and west to Mississippi. This is a very secretive snake, and their numbers are thought to be declining.
Hog-nosed snakes are not very large; average adult size is 14-21 inches. It has a thick body and sharply upturned, pointed snout. Adults are light yellowish brown (which is sometimes tinged with orange-red), with one row of large dark blotches on the back and smaller blotches on the sides. The underside of the tail and the belly are sandy gray. There is a dark line extending from the upper jaw through the eye; their pupils are round.
Their main prey is toads, but it will also eat frogs, other lizards, and small rodents. Controlling rodent populations on one’s property is an important step towards controlling the numbers of hog-nosed snakes.
While their coloring may not be spectacular, their behavior when approached is. Hog-nosed snakes are dramatic bluffers. First, they flatten their necks and bodies so they appear to be hooded, and will hiss and rear up. This leads people to call them puff adders or hissing vipers. If this tactic doesn’t work, they go into faux death throes, thrashing about, ending belly-up and motionless. In spite of all these dramatics, they are considered to be harmless to humans.
If you’re ever bitten by a southern hog-nosed snake, make sure to get it checked out. Southern hog-nosed snakes are not venomous, but with any wild animal bite there’s a risk of infection.

Southern Hog-Nosed Snake Control

There are several steps to dealing with snake problems: making your property less inviting to snakes, which includes making your property less inviting to the rodents they feed upon; and dealing with any snakes that are already there.

Habitat Modification for Southern Hog Nosed Snakes

In wooded, rural and riparian settings where snakes are common, their presence can be discouraged by eliminating stands of tall vegetation and removing piles of rock, lumber, and debris that might attract snakes to search for prey or shelter – especially close to buildings. Closing all entrances to rodent burrows make an area less attractive to snakes. It also helps greatly if one is persistent in controlling rats, mice, and field rodents in and around residences and other buildings.

Southern Hog-Nosed Snake Exclusion

· Structural gaps and crevices larger than 1/4 inch and within three feet of grade should be closed off; snakes can pass through very small openings.
· Screens on crawlspace vents should have mesh smaller than 1/4 inch.
· A thorough search should be made for cracks in the foundation, unscreened crawlspace vents, torn screens, and gaps around basement window frames.
· Check clearances under doors; seal any gaps with weatherstripping.
· Look for improper sealing where plumbing and utility lines penetrate the foundation of the building.

If you’re confident that you do indeed have a southern hog-nosed snake in your house, and you want to deal with it yourself, try this: place a trashcan on the side of the snake, and use a broom or a similar tool to gently sweep it inside the trashcan. Relocate it well away from residential areas, and seal up any openings in your house where it can get back in.
