Thrasher Termite & Pest Control handles a lot of pests, but the brown marmorated stink bug (BMSB) is a challenge even for us.
This non-native stink bug is a residential nuisance and a threat to U.S. agriculture and ornamental plants. California residents are advised to report sightings of the BMSB to the local UC Agricultural Extension office or to the County Agricultural Commissioner (see links below).
To identify a brown marmorated stink bug, you must get up close and personal. First scoop the bug into a baggie to avoid dealing with the “stink.” Then look closely. Does the bug resemble the one in the photo above? Do its antennae have two white bands? That’s the tell-tale sign that you’ve captured a BMSB and not a native stink bug.
These bugs are harmless to people: they don’t sting or suck blood, but they do smell when disturbed or squished and they like to spend winter in your house. You may start seeing them now, as they emerge in spring. The simplest way to rid your home of stink bugs is to exclude them by securing window screens and other openings. Once stink bugs are inside, they can be vacuumed up or you can make a simple stink bug trap with desk lamp, foil pan, water and dish soap.
In the garden, there are very few ways to combat these pests. Some people suggest row covers for plants, but this is a less than ideal solution for most home gardens. Others recommend hand picking. Pheromone traps tend to attract BMSBs to your yard and may increase the problem. Garden insecticides are not very effective against adult stink bugs.
