Pest removal can be a real bother to homeowners, but non-native creatures - known as invasive species - can be especially troublesome because the trees and plants in your yard likely have no natural defenses against these animals. Across the U.S. and the world, global commerce and other factors have made it possible for invasive critters to colonize new lands and wreak ecological havoc.
Keep an eye out for these dangerous invasive species, and should you find one in your backyard, make sure to contact the proper authorities.
1. Brown marmorated stink bugsThe stink bug can damage fruit and vegetable crops, but is also attracted to the warmth of suburban homes and businesses. Not only have the bugs caused serious agricultural damage, but these insects emit a foul stench and can even cause allergic reactions in some individuals.
2. Asian longhorned beetle
According to the Nature Conservancy, containment efforts related to this invasive insect are critical. The beetles have already been tied to the death of thousands of trees in urban areas such as New York City and Chicago. In fact, up to 30 percent of trees in the eastern U.S. are at risk from the Asian longhorned beetle.
3. Emerald ash borer
The larvae of these flying insects eat the inside of ash trees, and the Nature Conservancy reported that at least 60 million trees have been destroyed in 10 years because of these bugs. If there are any ash trees in your yard, it is important to be vigilant, as the prospect of a falling or rotting tree can be an expensive or dangerous problem.
Since being first discovered in Michigan in 2002, these invasive critters have spread to 25 states, as well as northern Canada.
4. European starling
These plants were first introduced to Central Park at the turn of the 20th century and since have spread throughout the U.S. These birds may seem like any other backyard visitor, but they are known to spread fungi and disease that can affect soil quality and even human health.
Be sure to close any open gaps or openings on the siding of your home or garage, as this can present an easy place for starlings to nest. Netting can also be used to prevent these birds from finding a home in the underside of an open shed or outdoor pavilion.
5. Hemlock woolly adelgid
The U.S. Forest Service reported that these insects, which are native to both the Western U.S. and Asia, have few natural predators in the eastern part of the country, and the hemlock trees that grow there have not evolved the same pest resitance. These little bugs are just a few millimeters long, but can cause damage to eastern hemlock trees by draining them of precious water and nutrients.
