Odor Management

Few consumers know where to turn when faced with a persistent odor issue on their property. Finding the source of the problem can be tricky and, at times, dangerous to untrained individuals. Pest Control Northwest's background in pest control and as a licensed building contractor provides the experience necessary to get to the source of strong, persistent odors.

Odor issues commonly arise from dead animals, animal contamination, open sewer or septic pipes, and mold spores from damp areas.

Women are usually most sensitive to odor issues, as they have more scent receptors on average than men.

Odors from Dead Animals

Dead animal odors increase rapidly, then diminish slowly over one to two months. Large, iridescent green or blue flies may be seen inside your home 10 - 14 days after the death of an animal. Odors are usually strongest in one room, and will eventually spread to a larger area. Those odors are caused by gasses emitted by bacteria as they digest the carcass.

Odors from Animal Contamination

Live animal urine and feces create gradually increasing odor concentrations in the air. When animals have nested in a crawl space or attic, odors are most noticeable when the furnace or air conditioning system is off since still air does not dilute odors and odor will easily enter living areas by natural convection.

Rodents shed tiny pieces of skin and hair called dander, adding to indoor air contamination. Rodents often live in the crawl space, which can provide as much as 40% of the air leakage into the home. This can result in a very significant problem for allergic and sensitive individuals.

Given the known unhealthy conditions in the average crawl space, Trey always recommends a thorough sealing of all floor penetrations to prevent air flow into the house. The same logic exists for sealing penetrations into the attic. In both cases, sealing will also significantly increase energy efficiency of the home.

Odors from Sewer and Septic Leaks

Sewer odors tend to come and go depending on atmospheric conditions and other factors, and will last indefinitely. Most commonly, plastic drain pipes are chewed through by rats seeking food or water. Although not as common, leaks can also happen when stressed plastic pipes (caused by weight pressure or an excessive bend) finally fracture and break open. Odors detected following contractor work on the building may indicate sewer pipes left open.

Trey has been able to locate septic tank failure as the source of an odor issue after following the scent left by gasses making their way along sewer pipes into a crawl space. He completely remedied this complex situation, resulting in a very happy customer!

Odors from Damp Areas

Excessive interior humidity can wet sheetrock walls and ceilings enough to enable fungi to colonize these surfaces. The fungi will actually eat the paper materials on the wall. These fungi are commonly referred to as mold and mildew.

These molds and mildew produce allergens and irritants, and potentially dangerous mycotoxins affecting respiratory health.

Ironically, today's more energy efficient building standards increase the potential for higher indoor humidity unless homeowners understand how to keep air circulating properly. Trey knows what to look for and how to implement effective solutions for reducing excessive moisture.
