Was It Squirrels?

Your children especially may find these furry creatures to be cute and fluffy, but do not be fooled by their appearance. When a squirrel feels threatened, they tend to become aggressive and will also resort to biting anyone who is in range.

These creatures are extremely confident little beings and will most definitely not shy away from causing damage to your attic, as they have very sharp teeth which they use to gnaw through a variety of materials, including electrical wires.

This poses a dangerous risk, as it very often causes house fires if the damaged wire(s) are not detected early.

Was It House Mice ?

Was It Sewer Rats (Norway Rats) ?

Sewer rats are actually Norway rats (among other names) but are generally referred to as sewer rats because they prefer the habitat of such spaces, however, they also like to nest in woodpiles.

They are very good climbers, and once they decide they want to trade the sewer for your attic, they can enter through an opening which may be as small as the size as that of a quarter. Once they are in your attic they will stay there and breed at an alarming rate

Remember: Prevention is Better than Cure

In all of the above cases, it is advised that you take as many precautions as possibly necessary to keep these creatures from entering your home and specifically, your attic.

Ensure that all possible entryways and holes, however small it may seem, are sealed off properly. Once they gain entry, there is no way for you to know what kind of destruction they may already have caused.
