Rodents destroy insulation, electrical wiring, plumbing, and other structural components of buildings. Insulation damage alone may amount to a loss of several thousand dollars in only a few years. Energy loss from damaged buildings results in added annual costs. Rodent-induced fires from damaged electrical wiring or nest building in electrical panels cause loss of property and threaten human safety.

The most effective means of limiting rodent damage is rodent-proof construction. New buildings should be designed and built to prevent rodent entry. Rodent-proofing is a good investment. Designing and constructing a rodent-proof building is less expensive than adding rodent-proofing later. Nevertheless, poor maintenance or management practices, such as leaving entry doors and unscreened windows open, will make the best constructed building susceptible to rodent entry. Techniques discussed here apply both to new construction and to the modification of existing structures. Junctures where utilities (pipes, cables) enter structures require special consideration in preventing rodent entry. Some earthquake design criteria require open spaces in important joints and other support areas, to allow for limited movement of tall structures. These present a real challenge in the design of rodent-proof construction. Call us for a free Survey.
