Invasion of the Ladybugs

If you have a light-colored house with southwest-facing windows, you might be surprised to see ladybugs beginning to make their home in yours. 

Ladybugs are probably one of the least offensive insects out there, but when they start showing up en masse in your house, you might not be too happy about it. These cute red and black beetles are creatures of habit. They like light-colored houses because heat more easily reflects off them. As for the southwest window, they love warm, bright areas where the afternoon sun keeps them comfortable. 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, the bugs 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 the bugs in a way that is stressful 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.

What’s Happening to Our Ash Trees?

Back in February, I read an article titled, “Every Ash Tree in CT to Die Within the Decade.” The headline couldn't be bleaker, but I didn’t really think about it again until this week as the trees began exploding in beautiful green. Ash trees are a staple in our area, with many standing proudly for hundreds of years. So what could be killing them, and what can we do to stop it?

The demise of our ash trees can squarely be blamed on an invasive, non-native species of beetle aptly named the emerald ash borer. It’s an insect that was first found in Michigan more than 20 years ago and since then, it has made its way to the east coast where it has made a feast of our beautiful, bountiful trees. In less than a decade from when the bug takes its first bite, it will eat the tree until it kills it. The mass exodus of ash trees now is because we’re hitting the eight-year mark from when the ash borers first made their homes in Connecticut. Now billions of Connecticut trees are dying all at once.

Emerald ash borers both eat ash trees and live in them. They lay their eggs underneath the bark and when the larvae hatch, it feeds on the tree’s most essential parts, the cambium or “growth” layer and the phloem or “circulatory” layer. The sheer volume of ash borer larvae is too much for a tree to handle and because they spread so fast, they can attack the tree much faster than the tree has the time or ability to fight for itself.

So is there a solution to the problem or are all of our ash trees doomed? Truth be told, the billions are trees that are already affected sadly don’t have a chance. What’s worse is that the emerald ash borer doesn’t have any native predators, so unless a tree has been treated with insecticide, it is almost certainly going to be infiltrated. However, there may be an unlikely ally that can help us protect future ash trees and maybe even save the species. It’s the parasitic wasp.

The name of this insect is very telling of how it operates. The parasitic wasp lays its eggs inside the body of an emerald ash borer and literally eats it from the inside out. They are currently being bred and shipped to Connecticut in an attempt to control the infestation of ash borers. But truth be told, the ratio of wasps to borers is barely enough to suppress the issue, nevermind control it. So the infestation will, unfortunately, have to run its course until the beetles eat themselves out of food and move on.

Until that day comes, the state’s Department of Agriculture hopes that new trees will develop a natural resistance to the beetle and that the hopeful decrease in their population will be controlled by the parasitic wasps. My advice? If you have an ash tree in your yard, it's worth a call to your local expert to find out more about the insecticides available to you. Trees that aren’t treated are in grave danger, so don’t wait to save yours.
