An increase in mice and rats is causing problems in some
eastern Iowa homes and ethanol could be to blame.
With the high demand for ethanol, farmers are
increasing their corn production which, in turn,
causes mice and rat populations to grow. Mice and
rat's eat and breed in corn fields, and can easily
make their way into your home through cracks in the
foundation and even dryer vents. “Just pretty much
look at the bottom of the foundation make sure all
your cracks and crevices are tied up and then it's
just a matter of, if you do have mice and rats inside
the house after you take care of the foundation, just
something as good as a good ol' snap trap,” said
Michael Jones from Hawkeye Exterminating Co.
Exterminators also recommend filling any visible holes
outside your house with steel wool, or any caulking product.
