| Exposure to rodents (mice and rats) has
been linked to increased asthma symptoms among laboratory workers who handle
rodents and are sensitized to them. Other studies have established links
between rodent allergies and asthmatic symptoms in lab workers. Research
published in 2004 found similar linkages in residential settings. Rodent
allergens are likely from rodent urine, saliva, or skin.
It is clear that many inner-city residents are exposed to and allergic
to rodents. A major study on asthma among inner-city children found that
nearly 20 percent of asthmatic children had been sensitized to rats and
15 percent were sensitized to mice. This is important to note, as research
has found mouse allergen in 82 percent of US homes.
Rodents can also expose humans to diseases such as hantavirus. Exposure
to such disease vectors is rare but can cause severe health problems.
Integrated pest management (IPM) approaches offer effective means of
eliminating rodents
from the 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 allergens may remain and can trigger allergic reactions in some
people.
