Examine your home to see where the stink bugs are coming in. Most often these bugs will congregate near the areas they come in at. Finding their entrance will help you eradicate them more effectively and quickly.
Vacuum the stink bugs as you see them and empty the contents of the vacuum outside immediately. True to their name, brown marmorated stink bugs release a protective odor when disturbed, which will stay within your vacuum if you do not immediately empty the contents.
Spray stink bugs with a handheld aerosol insecticide. Use caution; insecticides are poisonous. Make sure the insecticide is labelled for use indoors.
