At this point, we still do not have anything new to report in terms of recommendations as to how to address this problem. Kudzu bugs are attracted to light-colored surfaces but that certainly doesn't mean that brick buildings or those with dark-colored siding will escape the bug invasion. While shortcuts and easy solutions would be nice, there simply aren't any.
The emphasis still has to be on exclusion because chemical control is only partially effective and relies primarily on targeting the insects that are aggregating on surfaces. Preventive sprays are not recommended because they simply won't be durable enough to last the weeks during which these insects will be actively seeking overwintering sites. If you feel a treatment is required, stick with targeted treatments of critical areas: windows and doorframes, soffits, and eaves. If you choose to treat using a pyrethroid insecticide, remember to follow new label requirements.
