Stink Bug

The brown marmorated stink bug (BMSB) is a common pest that can cause significant damage to fruit and vegetable crops. These shield-shaped insects are about half an inch in size and are named for the unpleasant odor they emit when threatened or crushed.

BMSBs have a brownish color and may have copper, black, or gray markings. Their back legs are straight and cylindrical, which distinguishes them from the western conifer seed bug (WCSB). While WCSBs also have a shield shape and can be similar in color, their hind legs are widened and have a leaf-shaped area.

If you’re a farmer or gardener, it’s important to be able to identify these pests so you can take appropriate measures to protect your crops. BMSBs can cause damage by piercing fruits and vegetables and sucking out their juices, while WCSBs are primarily a nuisance pest that may enter homes in search of shelter.

To prevent infestations, it’s recommended to seal cracks and openings in your home, eliminate sources of standing water, and remove any potential food sources for pests. If you do encounter these bugs, it’s best to contact a pest control professional to safely and effectively remove them.

By understanding the differences between BMSBs and WCSBs, you can better protect your crops and property from these common pests.
