Roof
Rat
Characteristics –
Size: Larger rodents that may grow to a body length of 10 to 12
inches. Seldom will a rat weigh more than one pound.
Color: Can vary from gray to brown to black.
Found in coastal states, roof rats have long tails, thin bodies, and large eyes
and ears. Rats are more prevalent in urban and rural areas, and are found in
homes less often than mice because of their larger size.
Behavior –
Few people really like rats or mice, and no one wants them in their house.
Rodents live everywhere outside and could enter at any time, but fortunately,
this does not occur often. Usually, most home invasions occur in the fall, not
because of cooler weather, but because the seeds and plants on which rodents
feed outside are gone. Rats and mice must then seek new food sources.
Unfortunately, one of these sources may be your home. Rats are excellent
climbers and are capable of gaining entry through holes around soffit vents and
around cables entering the building, through holes in gable vent screens, and
through turbine and box vents on roofs. Many garage doors on homes allow enough
space for rats to fit underneath, as well.
Habitat – Outside, rats live in fields, wooded areas, vacant
lots, farms, and just about anywhere people have buildings. Rats are seldom a
problem in homes except in urban and rural areas. This is due in large part to
their size, since rats need a hole about the size of a quarter in order to gain
entry into a building. Rats however, may find harborage in many areas around the
home - especially in stacked firewood, stones and bricks, and piles of leaves or
other debris.
Tips for Control – The best way to avoid invasions of rats
is to (1) provide as little harborage as possible that might attract rodents,
and (2) seal as many holes and cracks in the outside of the home as possible
through which rats might enter. The following recommendations should be followed
to help prevent rats from seeking the food and shelter provided by your home:
 | Keep firewood stored as far from the home as possible and
store it off the ground. During the winter, store only enough wood next to
the house to burn every couple of days.
| If possible, remove any piles of debris, stones, bricks,
etc. If these are near the foundation of the home they serve as harborages
to attract rodents. Once there, it is any easy step for rodents to enter the
building itself.
| Seal any hole or crack larger than 1/4 of an inch. Large
holes or cracks should be stuffed with steel wool or wire mesh before
sealing with caulk or foam, otherwise rodents could chew through to enter.
| Install a good thick weather stripping on the bottom of all
doors to prevent rodents from entering. The garage door may prove difficult
to seal completely, so the door from the garage to the house must be sealed
tightly.
| Remember, your Carson service includes coverage for
rodents, and much of the service provided during the colder months is to
inspect for signs of rodents and to maintain preventive control measures |
