Maybe it’s a harbinger of bad insulation – or on a more optimistic note, perhaps a sign of good luck and an early spring – my overwintering crop of Ladybugs is waking up and beating at the windows to get out.
My first fall in Connecticut a few years back, the Ladybugs in my garden (or Ladybirds as some want to call them) slyly tucked into cracks and crevices in the façade of my house – over time making their way into the gentler temperatures indoors. I recall a courageous few blowing in with the opening of a door, or flying purposefully through an open window. Eventually I’d find them stowing away silently over the winter months tucked behind curtains and into window jams.
It’s important to note that Ladybugs are not structure damaging pests – if touched or terrified they can leave small orange stains as part of a defense reaction known as “reflex bleeding,” which is intended to prevent predators from eating them. But they don’t enjoy meals of wood or fabric as other insects do – and I’ve never suffered a bite although there some experts who swear they can land a well placed nip or two.
As a San Francisco Bay Area native, harboring Ladybugs (rather willingly or unknowingly) inside the home is something I really hadn’t seen before. They manage to survive horrendous weather conditions by finding a reasonable place to hide and then falling into a state of “diapause” – in which their metabolism lowers and simultaneously, their freezing points, as they drop into dormancy or bug hibernation. This is the reason Ladybugs are often stored in refrigerators at garden centers where they rest until released into a deliciously aphid laden garden. Ladybugs hiding in corners and crevices holding perfectly still may well be alive. Butterflies, moths, and silk worms also winter via a diapause.
In many antique and older homes hoards of ladybugs are commonly found in attics during the colder months – happily hunkered down in a quiet corner for a long winter’s nap. As insulation and better building practices advance, the tiny crevices and shrunken wood around windows that ladybugs rely on to gain entry into homes are getting harder to find. My home has new windows and paint – making insect entry inside quite a project.
Well sealed windows and doors notwithstanding, this last winter my ladybugs must have collectively realized they’ve found in me an agreeable host – I’ve always had a fondness for the little buggers – what with their cheerful colors and their willingness to devour aphids – they can eat up to 1,000 a day among other things – making them welcome workers in my world. During the spring and summer when so many other bugs and critters seem to be out to destroy what I’ve worked so hard to create – Ladybugs are part of my organic defense. As a result I’m careful not to harm them if I happen across them no matter what time of year.
I do tend to open windows quite a bit in the fall – hoping to catch some last gasps of fresh air before winter heating turns the house into a tightly sealed but somewhat stagnant micro environment. So in they come. I have neighbors who are appalled by this notion – tidily running around their houses with vacuum cleaner and dustpan in hand at the first sign of flitting orange spots, ridding the house of them.
If you’re not a fan of the notion of hosting a ladybug hotel during the winter be sure to caulk exterior cracks in the spring and summer before they come seeking refuge when the temps drop. Keep window and attic vent screens in good shape and be sure you have tight-fitting door sweeps in place on all exterior doors.
While I’ve probably painted a picture of swarms of orange in all corners of my house during the winter, generally I really don’t see wing or buzz of my ladybirds until the end of March – after the snow and ice have departed. I was really heartened a few weeks ago (mid February no less) when I found a few early risers ready to leave – flying against the windows to join the outside realm once again. Temps had began to rise earlier than normal and with the lengthening of days I saw this as an early sign of spring (Punxsatawney Phil had it wrong this year I tell you – the ladybugs have diapause to tell them when it’s safe to come out).
Every morning for the past few weeks I’ve gently scraped them off the window panes and released them. I love watching as they fly off into the warm sunshine ready for the spring – at first there were just a few – colors ranging from bright orange to pale yellow – some with spots, most solid. The past few mornings there’ve been upwards of 20 or more waiting to get out. These have been larger than the first and have many more black squiggles and markings than the early risers that first appeared a few weeks ago.
While I clearly have a collection on my hands (literally) most mornings, I’d love to see some of the red ladybugs I’ve seen described in books. Ladybugs can range from barely visible to nearly half an inch – and in a kaleidoscope of colors yellow and orange yes, but also scarlet, brown and solid black – making them easily mistaken for other types of beetles. The world over, there are more than 5000 species of Ladybugs – 450 alone here in North America.
And while it’s just early March, most of my ladybugs are already gone – but I know they’ll keep me company all summer long in the garden. I found this bit of advise while searching for images that I loved:

“Be well-rounded
Spend time in your garden
