Norway Rats
The Norway rat is larger and more aggressive than the Roof Rat. As an adult
the Norway Rat can weigh between 12-16 oz. with a body length of 6-8 inches
long. The nose is blunt with small ears, and small eyes. The fur is shaggy and
coarse with variation in colors. The tail is shorter than the head and body
combined, and scaly.
Rats will drag their tails, leaving a mark between their feet tracks. Unscented
baby powder or flour, lightly sprinkled can help you determine tracks and their
runways as they cross suspected areas.
Gnawing holes from rats are about 2 inches or more in diameter. They have
rough edges. They prefer to gnaw on wood, but can damage electrical wiring.
Rat burrows can be found along foundations, or beneath rubbish and shubbery.
If the burrow is active it usually clear of vegetation. Rat runways are smooth and
well packed. Indoors, these runways are free of dust and dirt.

The Roof Rat is smaller and more slender than the bigger Norway Rat. The
adults weigh about 5-9 ounces,7-10 inches long. The tail is longer than the
head and body combined. They have large ears and a pointed nose. The fur is
smooth, as opposed to the Norway rat with it's shaggy fur.
The Roof Rat is a climber, commonly nesting in areas above the ground: trees,
vines, attics, ceiling voids, or in voids along the roof line. These rats enter your
home much like squirrels. As their population grows they will nest in
underground burrows.
Roof rats are suspicious of changes in the environment or new foods, for this
reason it may take a couple of days for traps or poison baits to take. Rats are
nocturnal, with their peak activity at dusk or before dawn. When the population
is large or they are disturbed or hungry, you can see activity during the day.



Rats and mice can travel through numerous spaces. Sealing up areas, such as above, will
eliminate them from entering unwanted areas around your house and property.
McGrath Pest Control uses multiple methods in eliminating your rodent issues. Sometimes baits are necessary, and other times snap traps are required.
