Hosts are red, scarlet, white and pin oaks. Alfalfa is sometimes infested. Homeowners confuse adults with ticks except ticks do not fly and these weevils do and are attracted to lights. Weevils overwinter in protected places and females insert their eggs in the midrib of host tree leaves in mid-May. Larvae mine leaves of magnolia, sassafras and tulip popular until pupation in the midrib with adults appearing in large numbers in June.
New adults feed a week or more before aestivation.
Since some adult weevils do not fly, they can only gain entrance into buildings by crawling or hitchhiking on plant materials. Be sure to caulk cracks tightly. Special stripping around door sills, windows and other potential points of entry may be needed. Snug fitting screens and doors will reduce the number of weevils crawling into a building. Weevils are strongly attracted to water and can be trapped in shallow pans of water placed around the house foundations.
