Rodent Control for St. George and Southern Utah Homes
Scratching in the attic at night, droppings in the pantry, a chewed bag of dog food in the garage. Green Defense handles rodent control for families in St. George and across Southern Utah, from the first droppings to a home that stays sealed. We find out how mice or rats are getting in, remove the ones already inside, and help close the gaps so the next ones can’t follow. If pests come back between visits, so do we, free.
A rodent problem rarely fixes itself. Mice breed fast, rats are wary of anything new, and a few traps from the hardware store usually catch the slowest animal and leave the rest of the nest in the wall.

Mice and Rats We Handle in Washington County
Telling the two apart matters, because a mouse plan and a rat plan use different trap sizes, placements and bait. Your technician identifies what you have before anything goes down.
House mice are the rodent we’re called about most. They’re small and gray-brown, and they slip through a gap about the size of a dime. They nest in insulation, behind stored boxes, under appliances and in garage clutter, and they leave small, rod-shaped droppings along walls and inside drawers.
Norway rats are heavy, brown, burrowing rats with blunt droppings around three-quarters of an inch long. They’re less common in Southern Utah than mice, but when they show up they dig along foundations, under sheds and beneath slabs, and they chew through wood, plastic pipe and soft mortar to reach food.

Why Rodents Move Into Southern Utah Homes
Most homes here see rodent activity climb in fall, when cooler desert nights push mice toward warm garages, attics and wall voids. Homes in newer developments that back onto open desert often notice it first, because the edge of the lot is where wild habitat meets a heated house. Block walls, stacked pavers and rock landscaping give rodents cover right up to the foundation, while drip lines, pet water bowls and pool equipment supply the water.
Food is the other half. Birdseed and pet food stored in the garage, fallen fruit from backyard trees, open trash bins and a compost pile are an easy meal. Weep holes in stucco, gaps under garage doors, broken dryer vent flaps and the spots where utility lines enter the wall are the usual ways in.

Our Rodent Exterminator Process
Find the way in, remove what’s inside, then close the door behind them.
1. Inspect
We start by reading the evidence. Your technician checks the garage, attic access, pantry, cabinets under sinks, and anywhere you’ve seen droppings, gnaw marks or greasy rub marks along walls. Outside, we walk the foundation, stucco, weep holes, door sweeps, vents and utility penetrations, and look for burrows along block walls and under sheds. You get a clear picture of which rodent you have, where it’s living and how it’s getting in.
2. Eliminate
Next we deal with the rodents already inside. That means strategic trapping along the routes they travel and secured baiting where it fits the situation, placed with kids and pets in mind. Rats avoid new objects at first, so placement and patience matter more than the number of traps. We check activity on follow-up visits and adjust until it stops.
3. Protect
Removing rodents without closing the door just makes room for new ones. Exclusion is the long-term fix: we point out every gap a quarter inch or larger, along with the vents, sweeps and pipe openings that need screening or sealing, and we keep monitoring so new activity is caught early instead of next fall.
Mice Exterminator in St. George: Signs It’s Time to Call
If you’re searching for a mice exterminator in St. George, these are the signs that a few traps won’t be enough:
- Droppings in more than one room, or new droppings after you’ve cleaned
- Scratching, scurrying or squeaking in walls or ceilings at night
- Gnaw marks on food packaging, cardboard, baseboards or wiring
- Shredded paper, fabric or insulation stashed in a quiet corner
- A musky, ammonia-like smell in cabinets or storage areas
- Burrow holes along the foundation, a block wall or under a shed
- Pets staring at a wall, cabinet or appliance for no clear reason

Rodents are worth taking seriously. Their droppings and urine can contaminate food and surfaces, and gnawed wiring is a known fire risk. The earlier a population is caught, the smaller the job.
When You Need a Rat Exterminator
Rats are smarter and more cautious than mice. A rat exterminator has to work around that: they’ll steer clear of a trap set in the open, learn to avoid poorly placed bait, and keep using the same burrow until it’s dealt with. Large droppings, burrow openings two to four inches across, chewed garbage and thumping at floor level are the signs. Rats can also carry fleas and mites into a home, so an active rat problem deserves a prompt, professional plan.
Kid and Pet Safety
Rodent work happens in garages, attics and kitchens, the same places kids play and pets eat, so we plan around them. Traps go along walls, behind appliances and in spaces little hands and curious noses can’t reach. Bait is only used where it can be secured, and never left loose. If your dog or cat has free run of the garage, tell your technician and we’ll adjust the plan.

Mouse Control Between Visits
A few habits make a big difference to mouse control between visits:
- Store pet food, birdseed and pantry staples in sealed metal or hard plastic containers
- Pick up fallen fruit and keep trash and compost bins tightly closed
- Stack firewood off the ground and away from the house
- Keep garage doors closed at night and replace worn door sweeps
- Trim shrubs and vines away from the foundation and stucco
- Declutter the garage and storage areas so nests have fewer hiding spots
