It is officially bug season, and it is time to pay attention to your trees so you can keep them safe. Bugs are some of the leading causes of diseases in your trees. Once the bugs get a hold of the tree they can cause many issues, from creating caverns in the tree to leaf problems. When the problem gets too out of hand, the only solution would be tree removal in NH, but you can stop the problem before getting to that point if you know what to observe.
Bugs are a natural part of nature, and a few is not an issue. When your tree becomes infested with the bugs is when the genuine issues begin. In New England, we do not have many problems that plague us, but we do have a few that will plague our trees. Here are a few bugs, listed by Bayer, that we think you will see as you tend to your trees.
These insects form bumps on trees that could kill the tree if the infestation gets too bad. By sucking the juices from the plant, they can create black mold while attracting other insects like ants and wasps to them. They tend to feed on fruit trees and shade trees, and you can usually tell by looking at the bark or for yellowing/browning leaves. If you catch it early enough, you can try to identify the insect and use the proper spray or treatment options.
Eastern Tent Caterpillar
Caterpillars are adorable and turn into butterflies or moths. Either way there is a 50/50 chance on what they turn into, and for the most part, they are harmless. However, the Eastern Tent Caterpillar attacks trees throughout the early spring in the Northeast. A colony of these guys will typically spin nests in younger trees and feed off of the leaves like normal. However, where there are so many of them, they end up killing the young tree. The trees they tend to nest in include the birch, maple, oak, and some fruit trees like the apple tree – a lot of trees that are common in our backyards. The best you can do is to try to remove any of these webs when you first see them starting to form.
Emerald Ash Borer
Getting to the more invasive side of the bug issue with many trees, we get to the Emerald Ash Borer. This beetle is only about ½ an inch long, but it is the larva that you need to observe. These larvae eat the “tissue beneath the bark that moves water through the tree.” The only way to notice these guys would be their effect on an already dying canopy. However, once they get seen, trees could die within a couple of years. There is no way to prevent these bugs, other than insecticide treatments which will allow for them to die off, but it is only really worth it if the tree is still living.
Nature is beautiful and horrifying. When it comes to being able to figure out how to protect your trees, it comes to knowing the common bugs in the area. You will also need to talk to your arborist to see what trees you have. You can then do some research about what may affect your trees. As always, talk to KMA Tree Service and we will be able to help you find out if there is a chance of saving your trees or if you need tree removal in NH.
