The Annoying blue bugs of autumn!

Since time immemorial, the entire insect world has seemed intent on either stealing our blood or stinging us or ruining our crops and plants. Either way, they can make life miserable. People spend a lot of time in their yards, planting, pruning, and caring for their landscapes, with the aim of protecting their plants and trees from insects and making sure that they grow beautifully. However, many trees and shrubs have problems with pests such as aphids or other sucking insects. These insects excrete honeydew, a sweet, partially digested plant sap that is a main food of many ants. Plants with these sucking pests not only attract ants, but help feed and grow entire ant colonies. One such type of aphid is the blue ash aphid.

Woolly aphids (1)Blue ash aphids are small, blue-coloured insects that come from blue ash trees. They arrive after the first frost of the new winter season melts away every year. These insects are known by several names, conifer root aphid, blue ash aphid, Oregon ash aphid or smoky-winged ash aphid. Aphids feed by piercing host tissue and sucking plant sap through tube-like mouth parts. While removing plant sap, aphids may also inject toxins, plant growth regulators or pathogens along with saliva to aid feeding. Aphids excrete large amounts of honeydew which is essentially unprocessed plant sap. Many insects use honeydew and therefore are attracted to these colonies. The congregations give tree trunks a fuzzy blue appearance that extends up to three feet away from the base. Damage to the roots of fir trees can cause yellowing and stunting of small immature firs.

The blue ash aphids have a similar life cycle as normal, but instead of attacking the above ground parts of the plant they attack the roots of the plant. Like ordinary aphids they suck the sap from the plant thereby weakening it and possibly transmitting viruses and other diseases. When the infestation is heavy the plant or tree will wilt especially on dry days. The leaves may turn yellow and fall prematurely and the plant will be stunted. These pests often go largely unnoticed because they are underground. The damage they do show up mostly when the conditions are dry.

The below article would help understand the situation better.

Blue ash aphids invade Spokane

7631963_origSPOKANE, Wash. – Millions of little blue bugs can be seen just about anywhere in the Northwest.

You’ve probably seen them, there in your face, they invade your yard and many are asking what can be done to stop them.

Experts say the bugs are Blue Ash Aphids that come from Blue Ash Trees in the area. They come after the first frost of the season every year and stay for a couple weeks at least.

Phone calls have been flooding pest control companies and garden shops wanting to know how to get rid of them. Experts tell KHQ local news there’s nothing anyone can do but wait for them to leave.

Trees and plants should not be affected by them because most plant life has gone dormant anyway.

Experts also say they’re not a threat to public health.

The blue ash aphids are more of a nuisance than a threat. They are harmless to humans except for the sneezes they cause as we breathe them in. These pesky little gnat-like insects make breathing a challenge. Since they arrive in large swarms, complete eradication is not worth the time or effort and may be impossible. Thus we need a foolproof solution to deal with these pests.

At C Tech Corporation, we offer a safe and foolproof solution to deal with these tiny insects. Termirepel™ is a non-toxic, non-hazardous product that primarily repels insects from the application. It is a broad spectrum repellent which works against almost 500 species of pestering bugs thus efficaciously fending them away from the application. The best feature of this product is that it is environmentally safe and causes no harm to the insect as well as humans and the environment. It is available in masterbatch and lacquer form, and as a liquid solution. To keep these insects at bay, this product can be coated on the tree trunks in lacquer form. The repelling mechanism of the product would ward off the blue ash aphids and any other insect that could harm our trees.
