Yes, bats can cause quite a bit of damage to the attic. Their weight and movement from flying around can damage insulation, and they can chew through wiring and the walls. As if this isn’t enough, they leave their droppings throughout, which carry harmful bacteria and is dangerous for humans to breathe in, not to mention the extremely foul-smelling odor.

Carpet beetles don’t seek shelter in mattresses like bed bugs do, but there still may be sources of food, like the fabric of your sheets and blankets, that attract carpet beetles. Because these pests munch on plant-based materials, you could still find one in your bed as it’s searching for food.

Generally, squirrels are not considered aggressive toward humans. They are more likely to flee than confront people. However, like many animals, they may exhibit aggressive behavior if they feel threatened or cornered. If you approach a squirrel too closely or try to handle it, especially if it's a mother protecting her young, it may resort to defensive tactics such as biting or scratching.

The best way to ward off roaches is to take preventative measures and stay on top of routine extermination services. Keep them away by cleaning your kitchen free from crumbs, properly storing away food, covering your pet’s food bowl, and reducing moisture in your home to make your house less tempting for roaming cockroaches. Remove clutter—especially cardboard boxes that roaches love to hide in, and replace them with plastic tubs.
