Desert Rodents of El Paso: Pack Rats & Deer Mice
Meet the pack rats in your engine bay, the deer mice behind El Paso's hantavirus risk, and the other desert rodents a local pro hunts.
El Paso's rodents are not the same cast you would meet in Dallas or back east. Living on the edge of the Chihuahuan Desert and the Franklin Mountains means the city shares its rodents with the open desert, and a few of them are genuinely unique to arid country. Here are the desert rodents that make El Paso control its own specialty.
Pack rats (desert woodrats)
The pack rat is the signature El Paso rodent. These native woodrats build large nests called middens out of twigs, cactus, trash and anything shiny they can carry off, and they love warmth, which is why they crawl into engine bays and chew through vehicle wiring and hoses. Every winter, El Paso drivers discover a pack-rat nest under the hood and a repair bill to match. They also nest in garages, sheds, rock beds and cactus around the yard.
Deer mice and hantavirus
The desert deer mouse looks harmless but carries the region's most serious rodent risk: hantavirus. The virus spreads when dust from deer-mouse droppings, urine or nests becomes airborne, which is exactly what happens if you dry-sweep or vacuum a nest. Deer mice favor garages, sheds, outbuildings and rural and foothill homes. The rule in the desert is simple: never stir up a rodent nest dry, and let a pro handle cleanup with safe methods.
Rock squirrels
Up in Northeast El Paso and along the Franklin foothills, rock squirrels burrow along block walls, foundations and rocky slopes. They can undermine foundations and hardscape and carry fleas, and because they live right where the desert meets the neighborhoods, they are a constant foothill pressure.
Roof rats and house mice
El Paso also has the classics. Roof rats climb trees, power lines and block walls into attics, especially in the tree-lined, irrigated areas near the river and the valley. House mice do what house mice do everywhere, breed fast and overrun kitchens, but the desert climate keeps them pushing indoors much of the year.
Why local desert knowledge wins
Each of these rodents nests in a different place, enters through different gaps and carries a different risk, so identifying which one you have is the whole game. A local pro who works the desert treats a pack rat in a garage differently from a roof rat in an attic or a deer mouse in a shed. For authoritative information on rodent-borne disease, see the CDC.
