Roof Rats

The roof rat (Rattus rattus), also known as the black rat & house rat, is the most common invader of attics in Georgia.  The roof rat is a much more agile climber than the Norway rat and prefers elevated areas such as trees, vines, roofs and attics.  In addition to being a pest, this species of rat is a major vector of diseases, most notoriously the bubonic plague.

Signs of Infestation

Homeowners most often hear noises in the attic in the evening as rats are nocturnal.  This is typically the first indication that there is a problem.  Other typical signs of rat infestation are the presence of feces, urine, burrows, tracks and grease marks (where there are repeatedly used travel paths).  Gnawing is another indication of rat activity.  Rats can gnaw louver vents, fascia boards, soffit vents and areas at the roofline to gain entry to most attics.

Food sources

Rats are opportunistic feeders therefore capable of adjusting to various habitats.  Rats will eat about anything including birdseed, nuts, improperly managed garbage, pet food, ornamental and native vegetation and other small animals.


Roof rats produce litters of 6 to 20, with a gestation period of 20 – 24 days.  The newly born are completely reliant on their mother and remain in the nest for the first 17 to 23 days.  Rats reach sexual maturity in about 3 months and typically live longer than one year.  Depending on food supply and climate, they may breed year round with peaks during spring and fall.  A typical female may produce 3 to 6 litters during a lifetime.


According to the CDC, humans can become infected with diseases from rodents when they are exposed to fresh urine, droppings, saliva or nesting materials.  When droppings are moved around, spores can become airborne and can enter the human body through inhalation, eyes and ears.  Airflow could also create this same effect.  Exposed wiring is a fire hazard and rats are notorious for starting fires as they are constantly gnawing at materials including wiring exposed within attics and walls.  Rats also carry fleas, ticks, lice and mites and those parasites are in areas where nesting materials are so we often recommend homeowners have the soiled insulation removed and replaced once the rats have been trapped and the entry points have been sealed.

Rat Removal & Control

Our wildlife technicians provide non-chemical roof rat control which consists of trapping, rat proofing structures, removal & clean up of soiled insulation and disinfection.  Rats are capable of squeezing through holes only 3/4 inch in diameter (about the size of a quarter) and they are agile climbers and jumpers.  Rat proofing includes sealing off entry points with galvanized 1/4 inch hardware cloth or galvanized sheet metal.  Roof vent and dryer vent guards are installed to prevent entry.  Areas where utilities enter the home must be sealed along with foundation vent screening with galvanized hardware cloth.
