Pesky Little Bugs

Every year is the same thing. Brown bugs covering garages, getting inside sheds and houses, and making their way into window frames. It seems like an invasion in certain parts of the country.

Here in Michigan, we have no shortage of invasive brown marmorated stink bugs. Fortunately, they haven’t reached plague proportions, but they are still a nuisance. And thanks to the citizen scientists across the state, we now have a good idea of where they are! Thanks to regular residents reporting sightings, Michigan State University Extension has a better idea of the population of brown marmorated stink bugs and how they are distributed.

But there’s still more work to be done.

Most of the reports came from the southern part of the Lower Peninsula. That makes sense since that’s where most of the people are. So if you live (or visit) the Upper Peninsula or the northern Lower Peninsula, we still need your data! Read the article below to find out how.

 

Why and how to report sightings of brown marmorated stink bugs in your home or business

September 2017 update on why and how to report sightings of brown marmorated stink bugs to the Midwest Invasive Species Information Network.

When we first published this article in September 2015, we knew very little about where the brown marmorated stink bug (BMSB) would be found in Michigan. Now, thanks to the eager reporting by many hundreds of people who saw that first article, we now know it is well-established across most of the southern half of the Lower Peninsula (see map below). If you live outside of this area, especially in the northern half of the Lower Peninsula or in the Upper Peninsula, and would like to submit a report, please follow the instructions below. Otherwise, please check out the resources at the end of this article for more information on what BMSB is, what it is doing in homes and what to do about it.

What is the brown marmorated stink bug (BMSB)?

The brown marmorated stink bug (BMSB) is a 0.5- by 0.625-inch shield-shaped insect that uses its piercing mouthparts to suck plant juices from fruits, seed pods and nuts on a wide variety of wild and cultivated plants. It was accidentally brought to North America from Asia sometime before 1996 and was first detected in Michigan in 2010. Also known by its scientific name, Halyomorpha halys, BMSB adults and nymphs – the immature stages of the bug – feed on a number of important fruit, vegetable and ornamental crops. Where it has been established for some time, it is now a major pest for growers of susceptible crops.

Part of the pattern of establishment by this pest is that it starts out as a nuisance pest in homes and businesses and then a few years later it becomes an important agricultural pest for neighboring growers. At this time of year in their native habitat, BMSB would normally look for shelter in south facing rocky outcroppings and other protected areas. The perfect surrogate turns out to be south-facing walls of man-made structures. It is important to note that BMSB do not bite humans or their pets – they are strictly plant-feeding insects. Also, they do not nest or reproduce in homes, they are simply finding a place to take shelter from the cold and will atempt to find their way out again when spring returns.

For information on how to prevent or get rid of this pest in your home, plus how to distinguish it from other common insects that are occasional home invaders, see this tip sheet from Michigan State University Extension: “The Brown Marmorated Stink Bug (BMSB): Information for Michigan Residents on a New Home Invader.”

Who should report seeing BMSB?

If you or someone you know has seen this pest in or on the outside of your home or place of business, and you are outside of the area in which we now know it is well-established in Michigan (see map below), we want to hear from you! Go to the Midwest Invasive Species Information Network (MISIN) website or mobile app, register as a user (it’s free) and follow the instructions for submitting a report. A few minutes of your time can be incredibly helpful in officially cataloging and tracking this invasive pest.

The MISIN website and the app are free to use – you simply register and log in, verify you do indeed have BMSB (by either comparing the bug or bugs you see with the photo in this article, by looking at the Species Factsheet provided by MISIN for BMSB or downloading the new tip sheet on brown marmorated stink bugs for homeowners), and then report the sighting or sightings. Users can also submit up to two images with every report if they are uncertain as to whether what they are seeing is BMSB. By reporting sightings of this pest, you will be helping growers in your area prepare for this pest by identifying potential new hotspots.

If you have trouble registering with MISIN and would like to report a sighting, email Julianna Wilson at jkwilson@msu.edu with your nameaddress (or nearest crossroads), the date you saw them and how many you have seen. Again, if you have already reported from a particular address or live within the area where we know BMSB is well-established (see map below), we do not need to hear from you. Thank you!

BMSB 2017 Map

View larger image. As of September 2017, more than 12,000 reports have been submitted to MISIN from all but five Michigan counties. From these reports, we know BMSB is well-established in counties colored in red (darkest color), and we do not need any more reports if you see BMSB in these areas. Outside of the counties in red, we are interested in hearing where BMSB is being found. Reports should be submitted through the MISIN website.

Invasive Alert: Chinese Tallow Tree

tallowtree-fruitjpg-705a703f8770e9b6

The state of Alabama doesn’t worry too much about invasive plants like privet or kudzu, which have seemed to take over much of the south. No, the one botanists fear is the Chinese tallow tree.

Also known as the popcorn tree for the white, waxy tallow substance on its fruit that kind of looks like popcorn, this tree is so invasive in Alabama that they have taken to fighting it from the air.

So why should Michigan be concerned?

The U.S. Forest Service has data that shows the tree’s population has grown 500% between 1991 and 2005.

The tree thrives in wetland environments, but is not limited to them. The tree can grow in suburban areas, forest edges, and even sand dunes. It is still a popular ornamental tree in residential neighborhoods for its bright red fall color.

Yet once established this tree spreads quick. One mature Chinese tallow can produce 100,000 seeds every year. Those seeds are spread by birds and other animals, as well as flood waters. And the seeds can stay dormant for years before sprouting.

In addition to seeds, Chinese tallow has an extensive root system, with new shoots sprouting along it. These two things combined mean tallow can grow in clusters so thick that it drowns out all other native plants.

And it’s not that far away. According to a map from the University of Georgia’s Center for Invasive Species and Ecosystem Health, the plant was found in a county in southern Wisconsin as of July 2017.

The moral of this story?

Keep an eye out for plants that look unusual to you. It may be something that doesn’t belong. Learn from Alabama’s experience. If you find something you’re not sure of, check out the Midwest Invasive Species Information Network and report it if it’s invasive.

Be wary of what you purchase at a nursery or your local home supply store garden center. Make sure that it’s native to Michigan and you aren’t becoming the source of a new infestation of an invasive plant.

Alabama fears this invasive plant so much we attacked it from the air

Posted July 31, 2017, News from Al.com

When talking about invasive plants in Alabama, kudzu and privet tend to be the ones people are most familiar with, but they’re not the ones Alabama botanists and wildlife officials are most worried about.

One of those is the Chinese tallow tree, or popcorn tree, one of Alabama’s most invasive species.

The Stink Bugs Are Back

They’re brown, numerous, and annoying. And right now they’re trying to make their way into your homes. Brown marmorated stink bugs.

Every year people are plagued with these pests as they look for warm places to hide for the winter. Unfortunately for us, we’ve made lots of them with our obsession for cozy homes, insulated garages, even storage sheds and barns. All of these provide great protection for these insects during the harsh temperatures of winter.

If you find yourself infested, don’t panic. While irritating, they’re harmless. And there are ways to keep them out of your house.

The article below from Michigan State University Extension gives you a few tips and resources to help.

 

Brown marmorated stink bugs are moving into Michigan homes again

It’s that time of year again when brown marmorated stink bugs invade structures humans create looking for a place to hunker down for winter. Since last fall when Michigan residents were asked to report brown marmorated stink bugs in their homes, we now know that brown marmorated stink bugs are well-established as a nuisance pest in homes in the southern Lower Peninsula of Michigan.

What are they doing?

Brown marmorated stink bugs are looking for a protected place to hibernate over winter. They will leave your house again in the spring – if they can find their way back out – to look for plants to feed on and lay their eggs outside.

What are they NOT doing?

They are NOT nesting, laying eggs or feeding on anything or anyone in your house. These are plant-feeding insects with straw-like mouthparts for drinking plant juices – they are harmless to humans and pets.

What do you need to do?

  1. Don’t panic.
  2. Look for gaps around window air conditioners or holes in window screens and block them off – these are easy access points for brown marmorated stink bugs to enter houses.
  3. The easiest, non-toxic way to dispose of them is with a couple inches of soapy water in a bucket – the soap prevents them from escaping the water. Sweep them into the bucket and they will drown in the soapy water, which you can then dump outside. Or you can do the same with a Shop-Vac – add the soapy water to the canister before vacuuming them up with the Shop-Vac.
  4. Report how many you’ve seen at a given location using the Midwest Invasive Species Information Network. If you have trouble entering the information on the Midwest Invasive Species Information Network website, leave a message for Julianna Wilson via email at jkwilson@msu.edu or by phone at 517-432-4766 with your name, address (or nearest crossroads), the date you saw them, and how many you have seen.

The map below shows where we have received reports to the Midwest Invasive Species Information Network of brown marmorated stink bugs in the Lower Peninsula since Sept. 25, 2015.
