Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

When you’re checking for bed bugs in your home, start by searching for the telltale signs rather than the insects themselves, as they tend to stay hidden during the day. Here are the key signs of a bed bug infestation:

• Rust-colored or reddish stains on mattresses and bed sheets

• Dark spots on fabric

• Shed skins

• Fecal matter (looks like black spots)

As for fleas, you can typically spot them on your pet. If you notice them scratching themselves excessively, look for bites and bugs on their skin and fur.

You may find fleas in your bed if they followed you there on your pet or your clothing. While they will need you or an animal as a host, they can hide in bedding since it is warm and out of sight. If you spot signs of fleas or see live fleas in your bed, hire a flea control specialist immediately to eradicate the infestation and prevent it from spreading further.

In some cases, a clean house can have roaches, especially if you have excess moisture somewhere. You may want to check for leaky pipes or look underneath sinks to make sure water isn’t dripping near a hidden area that is inviting the cockroaches in. Roaches can also take up residence in clean homes with not-protected food sources, like open bags of food in a kitchen cupboard.
