Why are there so many ladybugs? Swarms of insects are invading houses in the US

Having trouble with swarms of ladybugs around your house this fall? We may have some answers.

As these little bugs look for a place to hibernate for the winter, their presence may become more noticeable. While some have taken to social media to post photos of their “infestation,” the uptick in the population is not typically seen across the country.

In search of a warm space to pass the winter

North Carolina is one of the states that often sees a surge in the ladybug population this time of year, and as they seek out a warm space to pass the winter, your home may be an inviting option. Those who live in more remote areas of the state will not be affected as much as those in urban centers, with Matt Bertone, a self-described ‘bug expert’ reporting to AOL that ladybugs typically “hibernate in leaf litter and under bark.”

There are three species of ladybugs or lady beetles that call North Carolina home, which also makes the issue more prevalent in the state. Further, since two of the species, Seven-spotted ladybugs (Coccinella septempunctata) and Harlequin or multicolored ladybugs (Harmonia axyridis) are not native, according to Bertone, there are fewer natural ‘checks’ to control their population. A few years back, the Capital Weather Gang also looked into this invasive species and the impact warmer falls have had on their growth.

However, it is not just those in the US that may see an increase in the Asian lady beetle (i.e., Harmonia axyridis), a cousin of the more common ladybug can be seen as far north as Toronto this time of year. These little creatures are not to be confused with ladybugs, but they share a shocking resemblance. According to Today’s Homeowner, these bugs differ from ladybugs in that they are attracted to “human homes” because of “their bright colors, warmth, and moisture.”
