Tips for keeping stink bugs out of your house
To keep the bugs out:
-- Seal and caulk cracks around windows, doors, siding, utility pipes, behind chimneys and underneath the wood fascia and other openings.
-- Repair or replace damaged screens on windows or doors.
-- Keep outdoor lighting to a minimum as stink bugs are attracted to lights.
-- If stink bugs have already entered a home, use a vacuum cleaner to remove them and dispose of the bag immediately outdoors, to prevent the bugs from crawling back out of the bag.
