Landscaping
Keep your branches and shrubs trimmed well. Those who use firewood should ensure that it’s stored 20 feet or more from the home and raised to be 5 inches off the ground. That way, the bugs don’t want to harbor in those areas.
Ventilate
Make sure that attics, crawl spaces, garages, and basements are ventilated properly to reduce the risk of harborage points. The areas may also need a dehumidifier. You may even use screens for the chimney and attic vents.
