WASHINGTON, DC — Snake calls are rising in several states this season, with pest-control operators, poison control centers and wildlife agencies reporting unusually busy weeks. The pattern is being linked to a mix of early warm spells, wet winter conditions that boosted rodent numbers, and suburban growth that is pushing homes and trails closer to snake habitat.
The states drawing the most attention include California, North Carolina, Texas, Georgia, Missouri, Tennessee, Florida, Virginia, West Virginia and Arkansas. In each place, officials and specialists say the problem is less about snakes suddenly changing behavior and more about weather and development creating better conditions for snakes and the animals they hunt.
Warm weather and wet winters are changing snake movement
Across the country, the basic pattern is similar: snakes become more active when temperatures rise, and they are more likely to turn up where food is plentiful. A wetter-than-usual winter can lead to more mice, rats and other small prey, which in turn supports larger snake populations.
When spring heat arrives early, snakes that would normally remain dormant can emerge ahead of schedule. That creates more chances for people to see them on trails, in driveways and around yards. In many places, the timing has been especially noticeable this year because warm spells came soon after heavy rain and dense plant growth.
California and Texas are seeing more encounters near homes and trails
In California, a wet winter followed by sudden spring heatwaves disrupted normal hibernation patterns. Wildlife activity has been especially noticeable in Southern California and foothill communities near Los Angeles, Ventura and San Diego, where rattlesnake calls have increased. The snakes involved are mainly Southern Pacific and Western Diamondback rattlesnakes.
Texas is dealing with a different scale of the same issue. With more than 100 snake species and subspecies, the state already sees plenty of encounters. But rapid growth in Dallas-Fort Worth, Austin, San Antonio and Houston is pushing snakes out of cleared land and into neighborhoods, where they may hide under pool decks, near hoses or around air-conditioning units during drought.
Suburban growth is putting people in snake country
In North Carolina, eastern copperheads are behind many of the state’s snakebite incidents. New subdivisions and paved greenway trails around the Research Triangle and Charlotte are cutting through hardwood forests, leaving snakes with more places to end up near people. Copperheads can also blend into leaf litter, mulch beds and garden edges.
Georgia faces a similar problem, especially in suburban counties around Atlanta. Researchers at Emory University have found that warmer spring temperatures are associated with more venomous snakebites statewide. Deep pine straw beds and decorative rock walls can also give copperheads places to hide close to homes.
Rural states are reporting dense clusters along property lines and trails
Missouri biologists say some parts of the Ozarks and central Missouri are seeing localized increases in copperheads and timber rattlesnakes. Heavy cicada activity and strong rodent breeding cycles are feeding those spikes, helping young snakes survive and increasing snake density along wooded property lines, rock walls and hiking paths.
West Virginia stands out for a different reason. The state has only two venomous species, the northern copperhead and timber rattlesnake, but it still ranks near the top nationally for snakebite rates per capita. Steep rocky terrain gives snakes plenty of winter dens, and spring activity spreads them across trails, bluffs and farmland.
Tennessee, Florida, Virginia and Arkansas are seeing snakes near houses
Tennessee wildlife handlers and exterminators have reported as much as a 50% increase in calls compared with average years. Many of the encounters are happening inside or beneath homes, where mice and rats move into cool crawlspaces, basements and attics and snakes follow. Rapid growth around Nashville and Memphis is adding pressure by disturbing established dens.
Florida snakes stay active for much of the year, but dry spells in Central and South Florida are pushing them toward irrigated lawns, retention ponds and pools. Virginia and Arkansas are seeing similar pressures: warm spring weather brings copperheads out earlier, while fluctuating weather and dry stretches draw rodents toward barns, porches and feed storage, followed by snakes hunting nearby.
How to reduce the chance of a snake encounter
Wildlife experts emphasize that snakes usually are not seeking conflict. They are looking for food, shelter or a warm place to rest. The most important safety step is to give any snake space and back away slowly rather than try to kill, catch or poke it, since most bites happen when people attempt to handle the animal.
Officials also recommend checking before reaching into brush, firewood piles or under logs, especially on trails and around yards. Keeping grass trimmed, clearing leaf piles and sealing gaps around vents, garage doors and pipe openings can also help. A flashlight at night is another key precaution, since copperheads and rattlesnakes often move after dark during hot weather.
