Roof Rat & Mouse Control in Snellville, GA
Scratching overhead only after dark? Droppings in the attic or under the sink? On an aging Snellville house, roof rats come in high through cracked roof parts and mice come in low through worn seals. Call us and tell us about the job — we will confirm the local crew for your county before any work starts.
Rodents in your Snellville home
The roof parts that rats use are some of the first to fail on a house built in the 1970s–90s. Each plumbing vent pipe on the roof is sealed by a rubber collar called a vent boot. After 15 to 25 years in Georgia sun the rubber cracks and pulls away from the pipe, leaving a ring-shaped gap a roof rat can slip through into the attic. Other common openings are ridge-vent ends, gable-vent screens and the spots where cable, phone and AC lines enter the wall. A rat doesn't need a tree to get up there either. Roof rats climb brick and vinyl siding with no trouble.
House mice come in from the ground. On houses this age, the rubber seal under the garage door has hardened and curled, weatherstripping on side doors has worn out, and the openings where the dryer vent and pipes pass through the wall have widened over the years. Rats and mice both breed all year in Georgia's mild climate, foul insulation and stored items with droppings and urine, and chew wiring. Baiting without sealing those openings just makes room for more.
Rat, squirrel or mouse?
Timing is the easiest way to tell. Roof rats are active only at night, so you'll hear them overhead and in the walls after dark. Squirrels are active by day, mostly in the morning and late afternoon. Mice are also active at night but tend to stay low, leaving tiny droppings in kitchen drawers, under sinks and along garage walls. Droppings are the other clue: rat droppings are larger and spindle-shaped, mouse droppings are small and pointed like a grain of rice. The pro confirms which you have, because rats and mice use different openings.
The roof parts that fail first
On a Snellville roof, a pro checking for rats goes straight to the parts that age fastest: cracked rubber vent boots, ridge-vent end caps that have blown out, gable-vent screens torn behind the louvers, and gaps where the soffit meets the wall at roof corners. Roof rats will also squeeze in through any gap where a roofline meets a wall. Each of these is small, but a rat can fit through a hole about the size of a quarter. A thorough inspection checks every one, not just the obvious hole.
Why bait alone fails
Bait kills some of the rats in the attic, but it does nothing about the openings, so new rats keep coming in. Poisoned rats also tend to die inside walls or under insulation where you can't reach them, and the smell lasts for about two weeks. That's why so many dead-animal calls start with a box of bait. Sealing the openings is what actually stops new rats from getting in. Traps then remove the ones already inside.
Health concerns
Rats and mice contaminate much more than they eat. Their droppings and urine soak into insulation and spread across stored boxes, holiday decorations and pantry shelves. Rodents are linked to salmonella and other illnesses, and roof rats in the Southeast are associated with murine (flea-borne) typhus. Don't sweep up droppings dry. Spray them with disinfectant first, or let the pro handle cleanup where the droppings are concentrated.
What the pro does: seal everything, then trap
A good rodent job follows a clear order. First, every opening is found and sealed with metal. Cracked vent boots get a new boot or a metal collar, ridge-vent ends get new caps, vent screens are replaced, and low gaps get steel mesh, a new garage-door seal or door sweeps. Then traps go into the attic and walls, and the pro checks them until activity stops. Some jobs are done quickly, and others take longer if there were a lot of rodents. Trimming branches off the roof helps, but since roof rats climb siding and brick, sealing the openings is what really works.
Mice, from the ground up
Mice are a ground-level problem on older houses. They come in through the gap under a worn garage-door seal, around the dryer vent, where the AC line passes through the wall, and through gaps along the foundation or sill. Then they nest in wall cavities, under cabinets or behind the dishwasher. Many of those gaps are smaller than a dime, which is why a mouse job takes patience. The pro has to check every low opening, especially in the garage, where most mice first get in.
