Will a bug bomb work to kill all gnats in your house?

A bug bomb can effectively kill many gnats in your house, but it may not eliminate all of them, especially if they are in hidden areas or if eggs remain. Additionally, bug bombs primarily target adult insects and may not affect larvae or pupae. For best results, combine the use of bug bombs with other control methods, such as removing standing water and using traps, to address the entire life cycle of the gnats.
