This big prehistoric-looking bug is walking on my ceiling. It has weird flared back legs and looks intimidating. Is it going to bite?

Their mouthparts are adapted for piercing and sucking plant material, and they do not have the capability or inclination to bite humans or pets.

Instances of these bugs biting humans are extremely rare and typically occur if the bug is handled roughly or feels threatened. Even in such cases, the ‘bite’ is more of a defensive jab with their mouthparts and is not harmful. Generally, these bugs are harmless and more of a nuisance than a threat.
