Notes

gs like to be together. They jam themselves cheek by jowl into tight spots like the inside of the air filter on your lawn mower. When stinkbugs find a suitable place to spend the winter they release an aggregation pheromone to let others know about it. This pheromone is not the same chemical that gives them their foul odor.

Stink bugs cause dermatitis in people when scratched by the sharp edges of a stink bug’s shell or exoskeleton. The result is swollen, reddened, itchy skin. Having a stink bug under your clothing and crawling up your arm or leg is most unpleasant, particularly if you are standing in line at a store or pumping gas into your car

They are attracted to the color yellow. If you put something yellow in your yard away from your house, it may keep the stink bugs outside and away from you

any stinkbugs sink their needles into plants. They use their needles to suck up the sap or juice that the plants use to transport and store food. Some stinkbugs stick their beaks into other insects and suck their body fluids. When not feeding, stinkbugs hold their beaks underneath their bodies between their front legs

Adults emerge from their overwintering sites in the spring, usually in early May. After they feed for about two weeks, they mate, and the females begin to lay eggs. Eggs are laid in clusters of about 28 eggs on the undersides of leaves from June to August. A single female can lay up to 400 eggs. Eggs hatch in three to seven days
