Don't Let Summer Mold Set Foot In Your House

This week I heard Meteorologist Bob Maxon say that this was the worst year for mold growth in Connecticut in recent memory. It’s easy to see why. Mold cannot live without water and the record rainfall we’ve had over the past few months means that our area is a veritable feast for fungus.

Mold is made up of thousands of microscopic spores that travel through the air until they land on a surface. They love to live in places that hold water, which is why you often see mold growing on trees, roofs, and other places that stay warm and damp. Indoor mold generally develops after being carried in from the outdoors and homes that tend to hold a lot of humidity are more susceptible to an infestation. Why is this a problem? Many people are sensitive to mold and mildew, especially children and the elderly. It can cause illness, asthma, and a host of other respiratory issues. The worst part is that mold grows and spreads incredibly quickly and cannot be contained without removing its food source.   

So how can you get rid of mold in your living space, or prevent it from making a home in yours? Here are my top tips.

1. Run a dehumidifier in your basement constantly. I have an air-tight finished basement and I still run a dehumidifier 24/7. The goal here is to keep your air humidity at or below 50%. When it’s raining, don’t be surprised if you have to dump the water hold twice a day.

2. Always use the extractor fan while showering or cooking. With so much water in the air from the weather, the last thing you want to do is add more inside your home. Be sure that your fans vent outside, not in the attic. Otherwise, you’ll just be redirecting the moisture to another part of the house.

3. Check your drainage. Gutters should be clean and in working order and your landscaping should slope away from the foundation so you don’t have standing water at the base of your home. Make sure your downspouts extend at least four feet out and away from the house.

4. An air conditioner is not a dehumidifier. Sure, it will remove some humidity but an air conditioner’s main function is to cool the air, rather than remove the moisture. If you find yourself running your A/C unit to control your humidity, you’re going to end up with an expensive energy bill and not too much to show for it.

5. Store soft goods in airtight plastic. People often put winter clothing and bedding up in the attic, which can be a breeding ground for mold if the area is not ventilated properly. Keeping the attic vented is key, good air flow can slow or even prevent mold growth.

In short, a house with high humidity is nothing to ignore. If you suspect that your home might be susceptible to mold, it’s worth purchasing an inexpensive humidity gauge called a hygrometer to find out. Remember, a mold problem can be a serious health risk to your family if not dealt with properly.

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.
