TERRE HAUTE, Ind. (WTHI) - This time of year, you may not only be noticing the cooler temperatures, but also some unwanted guests in your home.
You may think of them as "ladybugs", but Dr. Peter Coppinger from Rose Hulman says they are actually called "lady beetles", and this is the time of year when we really notice them.
"Usually what will happen, is in late October, when you have warm days followed by cool nights, that's kinda the trigger for them, that signal to try to find a nice warm place to hibernate".
Some people wonder what brings these insects into their home. Dr. Coppinger says they like structures that stand out.
"So if you have a brightly colored house amongst some woods, they're attracted to that, and specifically, they also like south or south west facing walls of your house, because that's where it's warmer."
Coppinger says these lady beetles actually help farmers, but if you really need to get rid of them, there's an easy way to do so.
"One method of getting rid of these in your home that is somewhat effective is to use a light trap. Now, not the buzzing one with the lights that electrocute the insects, but a black light."
And although the population is overwhelming right now, Coppinger says there is evidence to suggest the species will even out.
"It's thought that perhaps, maybe in the next coming years, or decades, the populations of these will eventually reach equilibrium and balance out, as predators start to eat these here, or natural diseases start to control the population."
But in the meantime, these little critters are harmless.
They like to congregate near windows and doors, trying to keep warm.
