Rat and Mice Control

Rats and mice invade homes in search of food, water, and shelter. Rodents can cause structural damage and potentially severe health issues due to the diseases they carry.  The most rodent damage is caused from nesting in insulation materials in crawlspaces and attics. They damage insulation with their urine, feces, and afterbirth in their nesting sites.

Rodents also chew electrical wiring and weather stripping which can lead to a potential house fire. Rodent droppings can also transmit diseases as well as other allergens, toxins, and bacteria.

The Center of Disease Control reported that at least 35 diseases are directly or indirectly transmitted by rodents. A single pair of mice can have hundreds of offspring in as little as four months. With PestFree™, we provide you peace of mind that your home is free of pests while still being environmentally safe as well.

Steps to Rodent Control:

Step 1: Inspection – Call our office for a free phone consultation or to schedule an inspection.

Step 2: Trapping – The technician will do a thorough inspection and damage assessment so he can give an accurate estimate for repair costs.  It is crucial to employ trapping methods at this point in order to eliminate the rodents before moving forward.

Step 3: Exclusion – The best form of rodent prevention is to shut them out of the structure. Mice can creep in through an opening as small as ¼ inch, but our experienced technicians know where to look for these openings.  Exclusion work is the process of locating and closing off or sealing the rodents’ points of entry to the home.

Step 4: Restoration/ Sanitization – In some cases, it is necessary to replace the insulation and vapor barrier in the home.  Rodent droppings, urine, carcasses, and other contaminates can cause considerable damage underneath the home and pose a health hazard.  The Triad Green Building Council estimates that 60% of the air you breathe on the ground floor of a home with a vented crawl space actually comes from the crawl space.  For this reason, many of our crawl space repair plans include sanitizing and deodorizing the entire area as part of the restoration.

Step 5: Prevention- The best form of rodent control is prevention. PestFree™ maintenance plans are designed to prevent a re-infestation of the home. This is primarily achieved through monitoring rodent bait stations around the exterior perimeter of the home on a bi-monthly basis.

Effective rodent control involves sanitation, rodent proof construction and population reduction. The first two are useful as preventive measures. When a rodent infestation already exists, some form of population reduction is almost always necessary. Reduction techniques include trapping and baiting.


Rodents can survive in very small areas with limited amounts of food and shelter. Consequently, no matter how good the sanitation, most buildings in which food is stored, handled or used will support house mice if not rodent-proofed. Although good sanitation seldom eliminates rodents, poor sanitation is sure to attract them and will permit them to thrive in greater numbers. Good sanitation will also reduce food and shelter for existing rodents and in turn make baits and traps more effective. Pay particular attention to sealing off places where rodents can find shelter. If rodents have few places to rest, hide or build nests and rear young, they cannot survive in large numbers.

Rodent-Proof Construction

The most successful and permanent form of house rodent control is to “build them out” by eliminating all openings through which they can enter a structure. All places where food is stored, processed or used should be made rodent-proof. Dried grain and meat products should be stored in glass jars, metal canisters or other re-sealable airtight containers.

Seal any openings larger than 1/4 inch to exclude rodents. Steel wool mixed with caulking compound makes a good plug. Patching material needs to be smooth on the surface to prevent rodents from pulling out or chewing through the patching compound. Seal cracks and openings in building foundations and openings for water pipes, vents and utilities with metal or concrete. Doors, windows and screens should fit tightly. It may be necessary to cover the edges with metal to prevent gnawing. Plastic sheeting or screen, wood, rubber or other gnawable materials are unsuitable for plugging holes used by rodents.


Trapping can be effective if there are only a few rodents present in a building. However, if a rodent witnesses another rodent getting caught in a snap-trap, they will avoid the traps. This condition is called “bait shyness”. That is why scientists have developed baits that take up to five days to kill them. Trapping is a highly effective method of rat control used in the communities around Seattle and Portland.

Bait Selection and Placement

Baits are available in several forms. Grain baits in a meal or pellet form are available in small plastic, cellophane or paper packets. These sealed “place packs” keep bait fresh and make it easy to place the baits in burrows, walls or other locations. Rodents gnaw into the packet to feed on the bait. Block style baits are also very effective for most situations. Proper placement of baits and the distance between placements is important. For effective control, baits or traps must be located where rodents are living. PestFree technicians use tamper-resistant bait stations to provide a safeguard for people, pets and other animals from accidentally getting to the bait. We place the bait stations next to a wall or in other places where rodents are active.
