Fall Rodent Control

Rodent Control

Rodents are known to spread over 35 different diseases worldwide. Handling rodents or being exposed to their urine, feces or saliva can put humans at risk of contracting any one of those diseases. This is especially troublesome during the cooler months when rodents are looking for a warm place indoors to call home. Effective rodent control is essential to eliminate the threat of disease.

Prevent Entry

The best way to control rodents is to stop them from getting in. Rodents get into the home through small holes and cracks. In fact, a mice can squeeze through a hole the size of a nickel. Look for holes in the roof among the rafters, around windows, doors, vents, foundation and seal them properly. Place screens on anything that connects the inside of the house to the outside.

Eliminate Rodent Food Sources

Rodents will go where there’s food and shelter. Keep food and food waste stored in plastic or metal containers with tight lids. Dispose of garbage on a regular basis. Don’t leave pet food out overnight. Remove weeds and debris near buildings and in yards. Don’t provide hiding places for rodents e.g. store boxes on a rack off the ground.


Traps can be used for rodents already inside the home. There are three types of traps namely a snap trap, live trap and glue trap. A snap trap is the most common and the one recommended by the CDC (Centre for Disease Control). Live traps should be handled very carefully because they often scare rodents and cause them to urinate. Their urine becomes a hazard because it could contain germs.

Poison Baits

Poisons can be used as a way to eliminate a rodent infestation but it is considered extremely risky for home owners. Over the counter baits are extremely hazardous and if not applied correctly, and in out of reach areas, can be fatal if accidentally ingested by children or pets. When we use baits for the control of rodent populations it is concentrated on the exterior of the home and always applied in locked and secured bait stations that are resistant to children or pets.


The diseases carried by everyday rats and mice can be directly and indirectly transmitted to humans and pets. Some of the most common rodent-borne diseases include Hantavirus, salmonella and Lyme disease. These can be transmitted through a rodent bite, urine, saliva or contact with rodent waste products. These diseases are serious and can be fatal e.g. Hantavirus pulmonary syndrome (HPS) is an often fatal disease caused by Hantavirus infection. Lyme disease is transmitted to humans by ticks that feed on rodents. If left untreated or inadequately treated, Lyme disease can lead to permanent paraplegia.
