Horticultural Pest & Disease Boards

For control options, reference the spray guides below and follow all label instructions on the pesticide.  The pest guides will give you more information on the biology and life cycle of the insect.

Some WSU Extension websites provide links to external sites for the convenience of users.  They may also provide page space to their county partners, county pest and disease boards and noxious weed control boards, that work with WSU Extension to help protect agricultural producers from damaging insects, plant diseases and noxious weeds.  These external sites and pages are not managed by WSU Extension.  Furthermore, WSU Extension does not review, control or take responsibility for the content of these sites, nor do these sites implicitly or explicitly represent official positions, policies or recommendations of WSU Extension.
