Are Ladybugs Taking Over Your House Yet?
Surprisingly, this hasn't started happening at my house yet, but here in the Q studio, it gets a bit nutty during the spring and fall. All summer, you never see a ladybug. Well, maybe one or two here and there, but not in any real numbers. But I have wondered previously why it seems there's more of them in spring and fall.
Turns out, the answer is quite simple. The weather. In the fall, you start to see them morer after the first frost or two, and when night time temps really start to take a dip. So they find their way indoors, or some place warm on the outside of your home.
When the weather gets cold enough, they will look for a gap in your siding or whatnot, and make their way inside where it's warm. Now, the good thing is, they don't do anything once they're in there. They just go dormant and sleep for the winter. Nor do they breed in your walls.
But come spring, when the warm weather starts to become a bit more of a thing, they will become active again, and start making their way back outside. If you choose to sweep them up, or vacuum them up, you should put them right back outdoors. They eat aphids, and protect our fruit trees and flowering plants, says the BDN.
At the end of the day, they're basically harmless, and they're benefits certainly outweigh the negatives. So live and let live. Besides, they might be doing you a small favor in the yard. Can that really be bad thing?
