| Exposure to rodents can trigger asthma
attacks. Studies have shown a linkage between rodent allergy
and asthma symptoms.
Integrated pest management (IPM) approaches offer effective means of
eliminating rodents from a home. IPM methods focus on preventing infestations,
trapping rodents, and limited use of lower-toxicity pesticides. However,
even after a rodent population is controlled, rodent hair, urine, and
fecal matter may remain, which can trigger allergic reactions in some
people.
Designing, maintaining, and renovating buildings to minimize
rodents is an effective prevention-based approach.
- Seal holes and cracks in building foundations,
utility openings, and joints between materials. Use corrosion-proof
materials such as copper or stainless steel mesh. Rodents can chew through
many other materials and squeeze through tiny openings.
- Add rodent barriers to foundation walls to make it more difficult
for them to enter a building. For example, heavy-duty wire mesh along
the outside of a foundation is an effective barrier.
- Seal passages through interior floors, walls, ceilings, and kick
spaces. If possible, keep kick spaces open to limit places rodents can
hide. (Kick spaces are the gaps between the bottom of cabinetry or built-in
furniture and the floor.)
- Keep bushes and trees at least three feet from
homes. Bushes and trees near a home provide food, a living place, and
sheltered passage for rats and rodents.
- Ensure trash is stored in secure containers (covered
garbage cans and dumpsters).
- Store food in rodent-proof containers.
