If you're concerned about pesticide residue in your home, there are a few things you can do to remove it. First, try vacuuming regularly with a HEPA filter to capture any airborne particles. You can also wet-mop floors and wipe down surfaces with a diluted vinegar solution. For more stubborn residue, you may need to scrub with a stronger cleaning agent or even sandpaper. If all else fails, call in a professional to help identify and remove the source of the contamination.
