The Brown Marmorated Stinkbug is joining the Asian Lady Beetle on the list of unwanted house guests.
The nonnative bug isn't harmful to human health, but it can give off an unpleasant odor.
Officials say the best way to keep the stinkbug out of your house is to use caulking, weather stripping and other measures to close cracks and other openings to the outside.
The agency says chemical sprays designed to block invading pests also work. Spraying should be done in early October to keep the bugs at bay.
