The Dangers of Rodents in Your Attic and Crawl Space

Attics and crawl spaces provide dark and remote protection that protects rodents against predators. Attics and crawl spaces have warm air and insulation that help the rodents stay warm during winter. These places are near stored food, pantry food, and pet food, making it easy for rodents to move between hiding and feeding areas. Openings near vents, foundation cracks, pipes, and wiring provide easy access and rodents nest quickly and establish a stable activity.

What Structural Damage Can Rodents Cause?

The following are the four points of structural damage that rodents can cause:

1. Chewed Wood & Insulation: Insulation and chewed wood make the house less stable in its support and control of energy. Rodents burrow holes in these materials and add pressure to heating systems during colder seasons.
2. Gnawed Wiring: Chewed wiring is a higher fire hazard because rodents chew through the wire coverings. This leaves the metal core bare and further possibilities of sparks within walls or attics.
3. Damaged Ventilation: Damaged ventilation affects airflow as rodents chew ducts or wedge nesting material into vents. The barrier prevents water vaporization and promotes the formation of molds in closed spaces.
4. Holes & Gaps: Small holes and gaps increase in size as rodents chew around them. These broad points of entry enable more rodents or insects to get in and disrupt the comfort of the indoors.

How Can Rodents Spread Disease in Attics and Crawl Spaces?

The rodents carry disease in attics and crawl spaces through urine and droppings that contain the hantavirus, leptospirosis, salmonella and other pathogenic organisms. Their bodies contain fleas, mites and ticks which leap into animals or human beings and begin to bite or irritate them. Dust contaminated by dry droppings or nesting material ascends in the air and reaches the lungs and exacerbating the breathing difficulties within the tight spaces and posing greater health hazards to everyday workers.

How Do Rodents Affect Indoor Air Quality?

The following are the three points where rodents affect indoor air quality:

1. Allergen Accumulation: Rodent hair, dander and urine particles are allergens that enter indoor air and increase the risks of allergy and asthma. These small particles get into the nose and lungs and cause sneezing, coughing and irritation in sensitive members of the family.
2. Odor Build-Up: Odor accumulation begins in rodents with a strong musky smell with ammonia when they urinate. This odor spreads to rooms and causes discomfort, particularly in enclosed rooms such as attics or stores.
3. Mold Growth: Mold growth occurs when moisture in nesting material or urine remains trapped in dark spots. This is a wet place where mould grows quickly and can cause respiratory problems for anyone in that place.

What Are the Signs of Rodent Infestation in Attics and Crawl Spaces?

The following are the five steps that are the signs of rodent infestation in attics and crawl spaces:

1. Droppings: Droppings are tiny dark balls that are found on insulation or on the walls. These pellets are active when fresh, meaning they appear wet and plump and rapidly multiply in places where rodents travel every day.
2. Gnaw Marks: Gnaw marks appear on beams, boxes and wiring as rodents have powerful teeth to continue chewing. These marks reveal the inner part of wood or plastic and assist in their normal pathways through narrow areas.
3. Nests: The nests are built in concealed areas where rodents collect shredded papers, cloth or insulation. These mounds of soft materials form warm nests and indicate that rodents spend hours there resting or breeding.
4. Noises: Noises such as scratching, scampering or squeaking also increase at night when rodents are active. These sounds pass through ceilings and walls and are used to locate the precise zone of motion within the house.
5. Grease Stains & Tracks: Grease spots and marks are dark smudges along the walls or across the paths. The rodents leave these marks when their oily hair comes into contact with the same path repeatedly, signifying their principal tracks.

How Can Rodents Impact Your Pets and Family?

The following are the four points where rodents impact your pets and family:

1. Bites & Scratches: Bites and scratches occur in rare cases when rodents are trapped. These wounds tear through the skin and expose them to infections, particularly in small children or pets that crawl around the dark corners.
2. Disease Transmission: Transmission of the disease increases via parasites and drops on human beings and pets. Fleas or mites leap off rodent bodies, causing irritation and the droppings that contain harmful germs spread to residential locations.
3. Food Contamination: Contamination of food begins when rodents have access to stored food in attic pantries or crawl spaces. They chew on packaging and drop droppings and transmitting germs that reduce the safety of dry goods and snacks.
4. Mental Stress: Mental stress is increased when the family feels that there is always rodent activity within the walls. This causes anxiety, panic and insomnia to both adults and children who experience scratching or a foul smell at night.

If you’re seeing Rodents, schedule a same-day inspection now!

What is the Most Effective Prevention Process?

The following are the five most effective points in the prevention process:

1. Seal Entry Points: Block openings by sealing the gaps using caulk, sealing vents and repairing roofs. The steps prevent habitual paths in which rodents travel and curb new activity in the attics or crawl spaces.
2. Reduce Clutter: Eliminate the mess by getting rid of stacks of boxes and unwanted materials. Mice and rats find no hiding places and relocate to storage sites that are open and readily accessible.
3. Regular Inspections: Frequent inspections enable the family to become aware of the droppings, nesting or sounds at an early stage. The habit helps to take action promptly and reduce the possibility of huge infestations within narrow areas.
4. Proper Storage: Food is also kept safe when families store food in airtight containers and pull items from the freezer. Keeping pets indoors eliminates odors that attract rodents to the indoors.
5. Professional Control: Professional control involves traps, bait stations or professional services to address larger issues. These techniques address active sites and decrease the rodent population in cases where home steps have minimal success.
