Is It Possible For Ladybugs To Endure The Winter Outdoors?

Ladybugs and ladybirds hibernate during winter and are naturally adapted to colder temperatures. Being inside can disrupt their hibernation cycle, so it is essential to keep them in a ventilated box with friends in a cool dark place. A greenhouse or outside porch can be a great place for them to overwinter or hide. Ladybugs use various strategies to survive winter, such as hibernation, migration, supercooling, and antifreeze substances. They seek warm and damp places for shelter, aggregate in groups, change colors, and conserve energy.

Most ladybugs can survive temperatures as low as 32 degrees Fahrenheit. However, they will find places in cracks, crevices, tree bark, and even your house or roof to spend the winter. In fall, they congregate in cliffs and rocky ledges where it’s sunny and warm, where they hibernate in groups throughout the winter. Without cliffs and rocky ledges nearby, they might be eyeing your house instead.

In the winter, native species tend to find warm places to burrow under tree bark or leaf litter. If you keep your home humidified well enough, they will survive and find their way to the sunny windows to try to get back outside once they are outside. A greenhouse or outdoor porch can be a great place for them to overwinter or hide.

Ladybugs can’t fly in cold temperatures below 55 degrees Fahrenheit, so it may be best to leave them alone if possible. Ladybugs are good at surviving harsh Canadian winters by overwintering in a warm place away from the elements of the outdoors. As the cold weather sets in, they migrate to hibernation hiding places each year.

What Temperature Should A Ladybug Be Outside In Winter?

Ladybugs can struggle to survive in low humidity environments. The optimal release temperature for ladybugs is between 65-80°F, ideally in the early morning with a humidity level of 40-60%. In winter, ladybugs can tolerate temperatures around 40-45°F but will die if exposed to temperatures below 35°F. Due to their cold-blooded nature, it is not advisable to place ladybugs outside during winter, as they become inactive in cold temperatures. It’s important to note that in North America, these insects are known as ladybugs, whereas in Britain and other regions, they are referred to as ladybirds.

During winter, ladybugs seek shelter in warmer locations like under tree bark or in leaf litter. If they are found indoors during this time, it is typically because they are escaping the cold outside. Ladybugs can endure the cold of a refrigerator but should not be kept there for more than a week, as prolonged exposure can lead to mortality. In warmer climates, they may thrive at higher temperatures compared to cooler regions.

Ladybugs cannot fly when temperatures drop below 55°F, making it prudent to acquire more ladybugs than initially intended for release. When releasing them, wait until the temperature remains consistently above freezing. When they wake from hibernation in spring, ladybugs will actively search for food. To support their well-being, maintain their habitat at a room temperature of 70-80°F and monitor for deceased ladybugs weekly. The ideal outdoor temperature for ladybug activity should be at least 55°F.
