Brown Marmorated Stink Bug: Invading Homes And Gardens Near You


Hi Guys. I am Trisha with Insectopia here to talk to
you about brown marmorated stink bugs. I will be calling them BMSB for short. We are going to be touching on how they became
an invasive insect, and the effects that they have on us. The BMSB is naturally found in China. They were first introduced to Pennsylvania
and Oregon by way of cargo ships delivering goods. They spread quickly due to human transportation
of fruits and vegetables and their natural mobility as nymphs and adults. The adult BMSB can be identified by the white
striping on the sides of the abdomen, the antennae, and the legs. You can also easily tell the difference between
the males and the females by looking at the bottom side of the end of the abdomen. This is what a male looks like. This is what a female looks like. These bugs are also common household pests
in the states where they are numerous. In the winter, these insects naturally stay
under the bark of fallen trees. They do not eat and they stay very still to
conserve energy. This is a lot like a bear’s hibernation but
in BMSB it is called diapause. House siding is akin to bark in that it is
a tight location that is protected from the weather. They climb under the siding and stay there
for the winter. When it starts to warm up outside, they attempt
to travel back into nature. Most of them make it, some confused insects
follow the warmth of the house and end up inside. They fly towards the sun and are blocked by
windows. They fly up towards the light and end up getting
chased by large mammals. BMSB have one main defense and that is their
stink! They use this smell to repel predators and
prove that they taste bad. This stink is meant to keep them alive. But, the BMSB that make it into the house,
generally will not make it out alive. If you are a homeowner trying to keep these
bugs out of the house, there is very little that you can do. These insects squeeze themselves into small
places and can end up in your walls. The best method as a homeowner is to make
sure that the holes, cracks, and crevices on the outside of your house are sealed. The adults that do make it out spend the season
eating and reproducing. They feed on a large variety of plants. They are confirmed to feed on 174 different
host plants. Top agricultural plants being corn, sunflower,
apple, and cherry. This makes them a huge agricultural pest. How huge? They destroyed approximately $37 million worth
of apples across Pennsylvania, Maryland, Virginia and West Virginia in 2010. That is just one year and one crop. The BMSB also attacks small home gardens. They really enjoy tomatoes, but they also
eat grapes, beans, and peppers. There is an opportunity to trap for BMSB. These are pyramid shaped traps. The BMSB are attracted to the pheromone in
the top, get trapped, and die. There are lures that will attract and to traps
that will kill them. This is the best that we have for the homeowners
at the moment. We do have a lead on control of this pest
on a larger scale though. There is another insect that is attacking
the BMSB. It is a parasitoid wasp and emerges victorious
out of BMSB eggs. That is a story for next week. This is what the brown marmorated stink bug
looks like in real life. Thank you for listening!! Our buggy question of the day is: BMSB traveled
from China all the way to the United States by ship, where would you travel to by ship? Make sure to like and subscribe for more videos

insect tale.

  1. A few years back I lived in a farmhouse that was infested with these stink bugs! I filled a large foil baking pain with water and a couple drops of dish soap and left it in the hallway outside my bedroom with a desk lamp shining on it. The stink bugs flew towards the light and landed up in the sudsy water. I woke up to over 50 of them floating upside down in the pan every day for weeks. It was a successful way to keep them out of my bedroom!
