Indiana Department of Natural Resources Outlines the Top 7 Most Invasive Pest Species Throughout the State.

These invasive insects don’t invade your home, they can be found outdoors in gardens and trees. However, they can still be damaging and costly.

The Indiana Department of Natural Resources  specialize in searching for, identifying, and researching invasive pest species. In this guide, you will be introduced to the top 7 most invasive pest species throughout the State of Indiana, as outlined by the Indiana Department of Natural Resources.

1. Asian Longhorned Beetle

This insect has a body that resembles a bullet. It ranges in size from nearly an inch to about an inch and a half. The body is black, with distinct white spots on the back. It has long antennae.

These pests are known to destroy maple trees, ash trees, and poplar trees.

2. Emerald Ash Borer

Emerald Ash Borer
This insect has a slender body and measure about a half inch in length. The color does vary from one to another; however, the most common colors are a tinted bronze or gold. The covers of the wings are emerald-colored. Larval feedings take place in the tissue located in trees between the sapwood and the bark. This, ultimately, kills the tree because of the fact that this drastically disrupts the transmission of the necessary nutrients needed to sustain life.

3. Giant African Land Snail

Giant African Land Snail
This amazing Indiana pest may grow up to 8 inches in length and 5 inches in width. This large snail feeds on over 500 different types of plant life, with the most common being melons, beans, and peanuts. If the pest is unable to locate any type of fruit and/or vegetable, it will consume plants that are ornamental in nature, the bark from trees, paint from homes, as well as stucco.

4. Granulate Ambrosia Beetle

Trypodendron lineatum lateral
These reddish-brown beetles are very small and have a head that faces downward. These pests are known to infest and feed on trees. These insects typically result in the wilting and dieback of trees. Eventually – if left untreated – the tree will die.

5. Gypsy Moth

Gypsy Moth. Lymantria dispar..Male(plumed antennae)
This pest originated in the United States as a means of starting a silkworm industry. Unfortunately, that endeavor failed. Now, it is considered to be one of the most damaging pests within the nation. It is brownish-red in color and appears to have hair on its side. This insect resides – mostly – in areas that are heavily wooded. They are capable of destroying a multitude of trees and plants. Here’s what you can do if you see a gypsy moth invasion

6. Japanese Beetle

Japanese Beetle - Popillia japonica, Julie Metz Wetlands, Woodbridge, Virginia
In Indiana, this insect is known to be highly devastating to landscape plants. They measure about 7/16th of an inch. Their bodies are long and have a green metallic-based color to them. The wings are usually a copper color. Spots of white-colored hairs emerge from just under the wing region. These pests feed on over 300 different types of plants. They feed in large groups and have the capability to quickly eliminate leaves, remove flowers, and destroy fruits and vegetables. Since 1919, our country has given up the fight, since they hitched a ride from Japan and have no known predators here. The most you can do are to set up bag traps or spray your most precious plants with insecticide made specifically for japanese beetles.

7. Pine Shoot Beetle

Tomicus piniperda (Linné, 1758) Syn.: Blastophagus piniperda (Linné, 1758)
This brown and/or black beetle can measure up to 4.8mm long. Their body seems to have two sections and displays a high shine. These insects are best known for attacking pine trees, but they will also attack healthy and/or dying trees.
