It’s that time of the year when mornings are met with crisp autumn air, when scarlet and amber leaves crunch beneath your feet and when restaurant menus are filled with everything pumpkin spice.

We may welcome the pitter-patter of trick-or-treaters knocking at our doors, but there are also unexpected and unappreciated guests sneaking into our homes: stink bugs, ladybugs and other 搜狐体育insects.

What draws these creepy crawlers into our attics and kitchen cupboards, and to the space beneath our furniture?

Not only are outdoor temperatures becoming colder, but days are getting shorter. Insects detect and respond to these temperature and light cues in preparation for winter. It’s an essential adaptive response since these insects are not able to cope with the colAAAAAAAAAA>Insects take on some of the most creative survival strategies. As the leader of the Stink Bug Project, I’ve seen how the invasive brown marmorated stink bug has overcome the challenges of our colder climate. Moving indoors during the winter has helped it spread across North America.

Head south or stick it out

Some insects, like monarch butterflies, pack up and migrate to warmer climates. Others stick around and brave it through the winter.

Those that can survive outdoors may enter a type of hibernation referred to as diapause. These insects burrow into leaf litter, under loose bark and in some cases at the bottom of ponds or lakes that do not completely freeze over.

The bodies of these insects will engage in biochemical changes. For example, some of these outdoor-dwelling insects may be able to resist freezing to death by producing special antifreeze proteins in their blood that prevent ice crystals from forming in their bodies and, by the end of a winter season, prevent tissue damage as a whole.
