Asian Lady Bug

Although most insects provide a natural benefit to the growth, decomposition, and health of trees, shrubs, and the eath, every now and then, a pest infestation arise that threaten to destroy our beautiful ecosystem. Knowing what type of insects these are can be helpful in treating and caring for your yard. Below we have listed some of the most common types of pests in the mid-west that can affect trees, shrubs, and landscape in the Fox Valley Illinois area.

Emerald Ash Borer

The Emerald Ash Borer is a very common type of pest found in the mid-west. It has destroyed millions of ash trees since it was first found in Michigan in 2002. It is an exotic beetle from Asia that feeds on ash tree foliage, usually making an irregularly-shaped mark along the margins of the leaves. It also makes a D shaped exit hole in the branches and the trunk of trees.  

If you suspect that you have an Emerald Ash Borer problem, the best way to treat it is by retaining professional services to save the tree and others within the quarantined area.

Native to Europe, Asia, and northern Africa, the Sirex Woodwasp is a destructive pest that not only destroys Pine trees itself but, leaves a nasty fungus behind.  The Sirex Woodwasp made its first appearance in an infestation in 2004 and they bring a mortality rate of 80% to the North American Pines it has affected. 

Fast detection and professional intervention can increase the chances of saving Pine trees from this villain before it’s too late.

Originating from Europe and Asia, this species was accidentally introduced to the USA in 1868. The Gypsy Moth feeds on a variety of trees including ash, birch, black gum, red gum, sugar maple, oak and many others. This moth causes widespread defoliators of forest and shade trees.  

The Gypsy Moth population can be naturally maintained by the White-footed mouse. Otherwise, the best recourse for these invaders is pesticide and professional care by Fox Valley Tree Service. 

  

 

Asian Lady Bug

Asian Lady Beetle (aka Asian Lady Bug) 

Introduced in the 1900s by the U.S. Department of Agriculture, the Asian Lady Beetle was released in various parts of the country to control other insects that were harming the environment.  Although they initially did their job, the not-so-beneficial aspects of this species of ladybug began to emerge. 

The beetle can cause a variety of health problems for people inside of their homes if they find their way into the siding, windows, soffits, and vents. Some people can have allergic reactions to the Asian Lady Beetle. Allergenic reactions can vary from eye problems, such as conjunctivitis (or “pink eye”), to hay fever, cough, asthma, or hives. Reactions can be triggered by touching the lady beetles then touching your eyes, or just by being around a large or lengthy infestation. These insects can also be aggressive and bite if they land on the skin. 

Pest-proofing measures such as assuring that windows and vents are sealed properly along with professional spray services and treatment can keep these bugs from getting into your home. 

 

 

Asian Long Horned Beetle

As destructive as it is creepy, the Asian Longhorned Beetle first made its appearance in the USA in 1996 by accidentally being introduced.  The larva of the beetle is approximately 50 mm long. Because of this, the damage that the larva do in the wood of the tree can be fatal. 

Larvae tunnel weakening branches so that they break in the wind. Heavily infested trees eventually die. 

If you find these insects in your trees, quarantine and professional assistance is necessary. Fox Valley Tree Service can help you maintain the health of your trees.
