What attracts stink bugs in your house?

Stink bugs are not native species and they react differently to the changes in temperature. The Brown Marmorated Stink bugs seek a warm place during winter. When the temperature drops down the stink bugs go into hibernation called Diapause.

Diapause: A period of suspended development in an insect, other invertebrates, or mammal embryo, especially during unfavorable environmental conditions.

During winter the Stink bugs seek shelter in your house. They sneak in through cracks, gaps, holes and even through windows causes infestation. They find shelter in the least used space of the house:

  • Basements
  • Attics
  • Storage spaces
  • Behind curtain foldings
  • Window moldings

During the stay at your house, they will be in the Diapause state. The state at which the Stink bugs will not eat nor reproduce. But if one stink bug makes its way in, it will attract others too. The Pheromones that stink bugs releases, will attract other stink bugs to the house.

Pheromone: A chemical substance produced and released into the environment by an animal, especially a mammal or an insect, affecting the behavior or physiology of others of its species.

They seek shelter until the spring. Most of them become active once winter is fading. They start to come out from cracks and fly inside the house. Also sometimes if the stink bugs are hiding near room heater or any heat source, they will be fooled by the temperature, thinking its spring. They will be active inside the house.
