Reasons You Shouldn't Move Firewood

  • The movement of firewood is the number one way that new non-native invasive insects get to new habitats.
  • Gypsy Moth egg masses can survive on the bark of trees or household goods and hatch in new locations.
  • Houses destined for Huricane Katrina releaf were delayed due to investation with Gypsy Moth egg masses.
  • Emerald Ash Borer (EAB) were introduced into the United States through the movement of wood packing material.
  • Emerald Ash Borere (EAB) can live in a cut log for over a year and still expand their population to new areas.
  • Asian Longhorn Beetle larva is often transported inside logs from location to location.
  • Other bark beetles and larva can be transported through the movement of firewood.
  • To find out more about how the EAB and other pests can be moved through your firewood, please watch this VIDEO.

 

 

Gypsy Moth Suppression Program:
The purpose of the Gypsy Moth Suppression Program is to protect Bay County's highly valued trees from the damaging effects of the gypsy moth caterpillar Gypsy moth populations can build to intolerable levels in a short time. When this build up occurs, the caterpillars will defoliate large trees in a few weeks, invade yards and recreational areas, and become a general nuisance to people living in infested areas.

Services offered by the Gypsy Moth Suppression Program include:

  • Monitoring all wooded and residential areas of Bay County for the presence of gypsy moth life stages.
  • Conduct suppression/control activities in heavily infested areas of the county. This includes determining where out-break level populations occur, contracting with an aerial applicator and conducting treatment projects in highly infested areas, and evaluation of treatment results.
  • Cooperate with the Michigan Department of Agriculture's (MDA) grant program for gypsy moth suppression to ensure maximum reimbursement on treatment and administrative costs. By following MDA guidelines and participating in the grant program, Bay County is able to reduce the cost of the program for Bay County taxpayers.
  • Conduct educational programs for schools, property owners, and local civic groups. The program utilizes Bay County Pinconning Park as a staging area for many of these presentations, which include information on the life cycle of the gypsy moth, how it fits into our local ecology, and methods for controlling the gypsy moth.

Emerald Ash Borer
The Emerald Ash Borer (EAB) is an Asian beetle that moved into the south-east corner of Michigan some time in the early 1990's. It's larvae feed on the cambium or conductive tissue just under the bark of ash trees.   

The emerald ash borer(EAB) is a very destructive insect that kill all species of North American ash trees. It is responsible for the death of millions of trees throughout Michigan and it has spread to 13 additional states and 2 Canadian Provinces. First found in the Detroit area of south eastern Michigan in 2002, the EAB were most likely introduced into the USA in wood packing material during the early 1990's. The Bay County Gypsy Moth Suppression Program responded to threat to our local forests by adding the EAB education and monitoring to Gypsy Moth Program Activities.

Beneficial Insects 
Many insects and related arthropods perform functions that are directly or indirectly beneficial to humans. They pollinate plants, contribute to the decay of organic matter and the cycling of soil nutrients, and attack other insects and mites that are considered to be pests. 

Asian Lady Beetle vs Ladybug
There is no difference. Both are lady bugs but the Asian variety has the habit of moving indoors for the winter in large numbers.
This is to make finding a mate easier in the spring.

Other Invasive Pests & Plants

Besides the Gypsy Moth and the Emerald Ash Borer (EAB), there are many insects and plants that can invade our yards and woodlands.  Please check out our information regarding Other Invasive Pests & Plants.


Pavement Ants - Winter Pests
Pavement ants typically nest in the soil, usually under objects, such as stones, bricks, sidewalks, and driveways. When they are found during winter, they are nesting in the soil under the concrete slab. When the nest is kept warm from the building's heat, the ants stay active, move through cracks in the concrete and actively forage for food and water. Ironically, many people that see pavement ants during winter do not see them in the summer. They are common in schools at this time of year.


Drain Flies - Winter Pests
Drain flies (family Psychodidae), also known as moth flies (they are not moths) and sewer gnats, are small gnats with large fuzzy wings. They are very commonly mistaken for fruit flies. Both are small, hang out in groups, and, in general, anger people. The drain fly did not get it's name by accident. When they are in the house, most commonly lay their eggs (10–200 of them) in the organic matter (e.g., hair, grease, food, sludge, etc.) that builds up in your drain pipes. When the eggs hatch (after two days or less), the drain fly larvae live in and eat that organic matter for somewhere between 9 and 15 days before emerging as adults. Adult drain flies are most active in the evening.  During the day they spend most of their time hanging out on walls and other flat surfaces, which makes it easy to kill drain flies. The adults usually live for around two weeks. But don't be fooled into thinking the problem is gone just because the adults have died off or you've killed them. If measures aren't taken to get rid of drain fly larvae and drain fly breeding grounds, you will never be rid of them.

Giant Hog Weed - Invasive Plant
Giant hogweed (Heracleum mantegazzianum) actually look like a beautiful architectural addition to the landscape. The plant was introduced from Eurasia by plant collectors in the early 1900s for arboretums and gardens. Reaching a mature height of 6 to 12 feet, giant hogweed may be aptly named, but can be difficult for the outdoor enthusiast to identify.  For more information about the Giant Hog Weed, please click HERE.
