Ladybugs in the House

If you have a light-colored house with southwest-facing windows, you may have started seeing ladybugs getting comfortable on your windowsills. 

Ladybugs are one of the least offensive insects out there, but when they start showing up inside your house, it can be a bit unsettling. These cute red and black beetles are creatures of habit and they like to stay warm. White and light-colored houses reflect the sun, making their dark little bodies a magnet for warmth. That’s also why you’ll find them sunbathing on your windowsills.  

So why now? Like many insects and animals, ladybugs hibernate during the winter and wake up in the spring. They find tiny cracks and crevices, generally around windows, to creep into a home and rest for the colder months. When they find a comfortable spot, they release a pheromone to attract others, which is why you generally find more than one or two. Then they rest through the winter and start to wake up around now, not unlike our bear population. 

While ladybugs might seem problematic, they are actually harmless. Unlike other wood and fabric-eating insects, ladybugs won’t feast on your home. On the contrary, as the weather warms, they actually look to get back outside. So if you are willing to be patient, they will leave on their own. However, if you have a large infestation or just hate the idea of bugs in your house, the best thing to do is to vacuum them up and dispose of them outdoors. Why a vacuum? Killing ladybugs in a stressful way will cause them to release their own blood, a yellow substance called hemolymph. This is a ladybug’s way of telling a predator that they are a no-good meal, but hemolymph also stains and stinks. Using a vacuum is gentler and will allow you to get the bugs back outside alive which is exactly where they want to be. 

As I mentioned, ladybugs will make their way back outside in the next few weeks but that doesn’t mean they won’t come back in the fall. Your best bet is to seal those southwest-facing windows to keep the bugs out and the heat in. Use caulk for small gaps or buy some weatherstripping to create a tighter seal around windows. Also, be sure to remove air conditioning units once the summer is over. Leaving them in will absolutely give ladybugs an opportunity to settle in for another season of comfort in your home.

Ladybugs in the House?

This week I received an email from a reader that read: Hi Bob, I was wondering if you know why I recently started finding ladybugs in my house. They seem to be congregating around the windows in one bedroom specifically. Why are they coming in and how do I get rid of them? Help!

This is a great question and a popular problem. My reader was surprised when I asked her if she has a light colored house, which she does. Strangely, ladybugs are attracted to light colored houses and the heat that reflects off them, which makes her home more susceptible to an infestation. I then asked her if the windows in question face southwest, which they do. I’m not a psychic but the reason I am getting the answers to these questions right is because ladybugs are very specific creatures of habit and certain traits make a house the perfect home for them. Warm and bright are the key components for a dream den.

Don't Let Winter Be a Time for Rodent Infestation

I recently received a question from a reader that I thought I’d share with all of you. She asked, “When the colder weather sets in, I sometimes get mice or rats in my house. I assume they are looking for a warm place to settle in and find food, but they aren’t welcome here! How can I deter them this year?”

My reader is right - her rodent problem absolutely has to do with the little buggers looking for a nice warm place to hide out from the winter weather and to grab a meal while they’re at it. Here are a few simple tips to reduce the chances of them making a home in yours.

Firstly, seal off the premises. Make sure doors and screens are always closed tight, and look for breaks, rips or holes that lead outside Generally caulk is a good sealant, but weather stripping around windows and installing new door sweeps on doors will keep insects and small animals out and will do double duty by helping to insulate your home for winter.

For bigger areas such as the chimney, you can use a thick wire mesh to keep the critters out, just make sure the material is thick enough that it can’t be chewed through. Believe it or not, a mouse can get through a hole the size of a dime, so be diligent in your search for entry points.

Another tip is to make sure you don’t leave any food lying around. Mice and rats are pretty resilient to the cold, but they have to eat to survive and looking for a meal in your house is a lot easier than trying to find one outside in the cold. Many pet owners leave animal food out for long periods of time, which makes a delicious meal for a rodent. If a mouse can get into your house, the last thing you want to do is give them a reason to stay. Keep that food, pet or otherwise, sealed up tight.

If you have a garden that thrives through the autumn, that’s most likely where your rodents are coming from. They are smart, and they’ll be waiting to dart through your door at a moment’s notice. As a general rule of thumb, keep edible plants at least a few feet from any door, and the same goes for your garbage bins.

If your home is susceptible to rodents and you’ve tried to get rid of them with no luck, you might want to consider having the problem dealt with by a pest control professional. There are plenty of traps, sprays, and natural solutions on the market, but using the wrong deterrent might drive pests up into the walls where they can start chewing on wires and causing longer term, more expensive damage.
