The color brown is said to represent ruggedness when used in advertising .  Pullman Brown  is the color of the United Parcel Service (UPS) delivery company with their trademark brown trucks and uniforms; it was earlier the color of Pullman rail cars of the Pullman Company , and was adopted by UPS both because brown is easy to keep clean, and due to favorable associations of luxury that Pullman brown evoked. UPS has filed two trademarks on the color brown to prevent other shipping companies (and possibly other companies in general) from using the color if it creates "market confusion". In its advertising, UPS refers to itself as "Brown" ("What can Brown do for you?").
It is not advisable to use an insecticide inside after the insects have gained access to the wall voids or attic areas. Although insecticidal dust treatments to these voids may kill hundreds of bugs, there is the possibility that carpet beetles will feed on the dead stink bugs and subsequently attack woolens, stored dry goods or other natural products in the home. Although aerosol-type pyrethrum foggers will kill stink bugs that have amassed on ceilings and walls in living areas, it will not prevent more of the insects from emerging shortly after the room is aerated. For this reason use of these materials is not considered a good solution to long-term management of the problem. Spray insecticides, directed into cracks and crevices, will not prevent the bugs from emerging and is not a viable or recommended treatment.
