Landscaping
Maintain your bushes and branches well-trimmed. People who use firewood should store it at least 20 feet away from the house and 5 inches above the ground. That way, the bugs are less likely to congregate in certain regions.
Ventilate
To limit the possibility of harborage points, ensure that attics, crawl spaces, garages, and basements are properly ventilated. A dehumidifier may also be required in certain regions. Screens can even be used for the chimney and attic vents.
