Michigan’s Most Wanted

A "No Invasive Pests" logo

Pests serve important roles in maintaining nature’s balance, but only in their proper place. When human tampering alters nature, pests thrive more than they naturally would. Every role in an ecosystem is interconnected, so when one element thrives too much, it throws everything off.

One of the worst consequences of ecological disruption are invasive pests. Pests are invasive when they don’t naturally occur in the environment they inhabit. When these species enter an ecosystem, they can significantly throw off its balance.

According to the Michigan Invasive Species Information Network (MISIN), Michigan is at risk from 18 species of invasive insect. The four covered here pose the greatest threat to our environment. We consider them “Michigan’s Most Wanted,” and we’re putting the bounty out: here’s what you should know about these four desperados, and how you can help stop them.

The Brown Marmorated Stink Bug

Brown Marmorated Stink Bug

The stink bug is a mottled-brown, shield-shaped bug that superficially resembles a small beetle. Adults grow to .5 to .75 inches long. Look for white bands on the legs and antennae, and black-and-white patterning along the abdomen. Stink bug nymphs tend to be orange or reddish. These pests typically live near their food sources: fruit trees, vegetable crops, and ornamental plants. Come winter, stink bugs attempt to move to sheltered areas such as houses.

According to Michigan.gov, the brown marmorated stink bug can adversely affect fruit, nut, and legume crop yields. They also damage ornamental plants. When stink bugs feel threatened, they release a foul odor. This odor also emanates from their bodies after death. Their smell and constant presence can make stink bugs an annoying pest to have around your house.

Balsam and Hemlock Woolly Adelgids

Balsam and Hemlock Woolly Adelgids are two different species in the Adelgidae family and Adelges genus of insects. Of the two species, only the Hemlock Woolly Adelgid has been positively identified in Michigan, but both species are on Michigan’s invasive species watchlist. Adelgids are small, pill-like bugs. As they grow they produce a distinctive wool-like wax filament covering. Look for woolly pilling on the branches or bark of trees.

Balsam and Hemlock Woolly Adelgids feed on the sap of balsam fir and hemlock trees. As an Adelgid feeds, they secrete a salivary substance into the tree. This substance stimulates unhealthy growth  that weakens the tree. Vulnerable trees may die as a result of Adelgid feeding and also become more vulnerable to weather and other pest damage.

Asian longhorned beetle

Asian Longhorned Beetle

The Asian Longhorned Beetle is one of the few pests considered so dangerous that possessing it in Michigan is illegal. The beetle is typically .75 to 1 inch long. They’re a shiny black with white spots on their bodies and white bands on their antennae. While the pest isn’t in Michigan, they’re established in NYC, Illinois, Massachusetts, New Jersey, and Ohio, so they may be headed this way.

Adult females dig holes into maple bark and bury eggs inside them. When the eggs hatch, the larvae feed on the inside of the tree, creating tunnels in the process. Mature larvae can penetrate the tree’s heartwood, substantially compromising its sturdiness. There are more than a billion maple trees in Michigan, and all of them would be at risk should Asian Longhorned Beetles invade our state. If you suspect you’ve identified a Longhorned Beetle, contact the MISIN immediately!.

Emerald Ash Borer

Emerald Ash Borer

Like the Longhorned Asian Beetle, Michigan prohibits the Emerald Ash Borer. Unlike the beetle, the Ash Borer is already established here. The Emerald Ash Borer gets its name from its bright, metallic green coloration. Adult Ash Borers are about half an inch long. Ash Borer larvae are cream-colored and resemble fat worms.

Ash Borers have killed tens of millions of ash trees in Michigan. The insect feeds on ash tree foliage and lay eggs in its bark. Larvae squirm under the bark to feed, creating S-shaped tunnels under the surface. The holes produced damage Ash tree structure, depriving them of nutrients. Michigan’s currently engaged in all-out war against the Emerald Ash Borer, so if you see one, let someone know!

Invasive pests aren’t just a problem for your house or yard; they’re a problem for the whole state! If you suspect you might have an invasive species infestation near your home, let the MISIN know and then give us a call. Together, we can protect the beautiful nature of Michigan!

Michigan’s Most Pervasive Pest Problems

We’ve been in the Michigan pest control business for a long time, so we’ve seen a lot of pests. Some more than others, unfortunately. Michigan has a handful of pests that show up like bad pennies year after year to plague our homes and businesses. If you’ve been here long, chances are you or someone you know has had a run-in with these pesky creatures at some point.

Fortunately, because we deal with “the usual suspects” every year, we know quite a bit about their home-infesting MO, and even more about how to counter it. Follow these suggestions and you’ll be able to keep your property pest-free–not just this year, but for all the years that follow too.

Spiders

Spiders have adapted to virtually every environment and can be found all over the world. If it seems like Michigan has a particular problem with the eight-legged arachnids, it’s because despite their adaptations, spiders can’t survive freezing cold. When the temperature begins to drop, spiders migrate out of their typical homes in forests, fields, and gardens in order to find shelter. Consequently, most of the spider infestations we treat originate in the Fall or early Winter.

To keep spiders out, start outside. Circle the perimeter of your home a few times. Clear away anything that’s leaning against the house. If you have a pile of firewood, move it away from your house. Regularly trim your hedges and bushes. Look for avenues of infiltration like gaps in the foundation or near utility lines and seal them. Spiders are attracted to cover near houses, because they’re good spots to build webs. Once they’ve found cover, they’ll start looking ways to get somewhere even better – inside your home. Don’t give them any opportunities.

Bed Bugs

Bed bugs quickly become a problem for areas with a mobile populace and/or old buildings. They love to hitch rides with travellers. They hide in luggage, bedding, clothes, and anything else they can get into. After their inadvertent host brings them home, they make themselves comfortable and often even lay eggs. These eggs hatch, and then another building has a bed bug infestation.

The best way to prevent a bed bug infestation is to take precautions when traveling. Check in and around your hotel room’s bed right away. Studies have shown that most bed bugs are found within 15 feet of the bed. Keep your luggage off the ground and, if possible, sealed in airtight bags. You should also consider running luggage through your dryer right away when you get home. Heat is the most effective means of killing bed bugs. For a lot more info on stopping bed bugs, check out the official Michigan Manual for the Prevention and Control of Bed Bugs.

Termites

Subterranean termites are highly active across Michigan’s lower peninsula, particularly in Grand Rapids, Ann Arbor, and Detroit. The most common, the Eastern Subterranean Termite, is the most destructive wood pest in the state. These termites live in colonies and feed on dead wood. Subterranean termites carve elaborate tunnel systems underground, which they use to access food sources from below. Termites also require moisture and warmth, so they target places where they can get moisture, warmth, and wood all at once.

Make sure they can’t get these. Termites seek out places where wood touches the ground. Limit access to wood like this. Wrap barriers around the bottom of deck posts. Treat wooden flooring to prevent rotting. Make sure wooden siding is off the ground. Remove excess cellulose (wooden) materials like cellulose mulch. The subterranean terrors are looking for moisture, too, so watch for condensation or puddling. Repair leaks immediately. If termite problems persist, give us a call quickly to spare yourself costly property damage.

Cockroaches

Like spiders, cockroaches are adaptive and can be found almost everywhere. Michigan has five varieties of cockroach: the American, German, Oriental, Brown-Banded, and Wood cockroaches. The German roach is the most annoying, because it wants to get indoors. Cockroaches are common in urban areas where they can find easily-accessible food and shelter. Cockroaches will eat just about anything, so they’re attracted to trash.

To prevent cockroaches, organize and clean. Organize your home to prevent clutter. Avoid stacking cardboard boxes, don’t keep anything on the floor, and don’t leave food out overnight. Keep a cleaning schedule. Vacuum once a week, wipe surfaces after meals, and watch for dust and grime accumulation. Cockroaches don’t need much to thrive, so you can’t give them anything. After cleaning, pay attention to moist areas and caulk gaps in your foundation or siding. Cockroaches can climb sheer surfaces, so don’t assume anywhere is out of reach!

Following these tips will go a long way toward preventing pest infestations, but the problem with Michigan’s most pervasive pests is their persistence. If you do end up with an infestation, there’s no need to panic. Just call Griffin pronto! We’ve got plenty of practice putting these pushy punks in their place, and we’d be perfectly pleased to pummel your problem, too. It would be our pleasure!

Fall’s Bounty Includes Occasional Pests

Fall’s turning leaves and cooler temperatures make you think of football, hayrides and Halloween but it also marks a rise in sightings of stink bugs and other occasional pests around homes.

Stink bugs, spiders and ants seek to enter homes at the onset of cooler weather looking for overwintering spots. Griffin Pest Solutions encourages Michigan homeowners to take the necessary steps now to deny stink bugs and other fall pests access before they invade in droves.

Stink bugs were truly an occasional pest a few years back but they have quickly spread to more than 40 states, including Michigan. While mainly a significant threat to agricultural crops, stink bugs can be a major nuisance for homeowners.

What gives them their unique name? Stink bugs release a chemical alerting their fellow pests to an area they’ve settled in and they secrete a bad-smelling, bad-tasting fluid when disturbed or when crushed. Stink bugs will gather near windows, lights, TVs or computer monitors that throw off light and warmth.

Web-spinning spiders can be found in many locations in and around a home. And while spiders are quite beneficial to our eco-system – they eat unwanted insect pests – they are aesthetically unappealing and creep people out.

Spider webs – which are often regarded as one of the strongest natural fabrics and can be built and rebuilt overnight – are half as strong as a steel thread of the same thickness and more elastic. Spider webs are found in garages, carports, eaves, attics, sheds, around windows and other places around your home.

Griffin Pest Solutions offers the following tips to keep stink bugs, spiders and other fall pests from gaining access to your home:

  • Suck and Sweep Pests Away – Regular vacuuming or sweeping of windows, corners of rooms, storage areas, basements, and other seldom used areas to remove spiders and their webs. A spider’s soft body does not survive this process. When vacuuming for stink bugs indoors, empty the contents in to a plastic bag and dispose of them immediately.
  • Seal Cracks and Crevices. Seal cracks around windows, doors, electrical outlets, ceiling fans and light switches. Pay close attention to areas including around siding and utility pipes, underneath the wood fascia or other openings.
  • Inspect Packages and Boxes. Inspect items such as boxes of decorations and grocery bags before bringing them indoors. Plants and firewood are also as modes of transportation for spiders and other pests – store firewood off the ground and away from the house.
  • Maintain Your Landscape. Outdoors, you can eliminate pest hiding places and spider web-building areas by keeping your yard free of trash, leaf litter and overgrown vegetation. Make sure to trim shrubs and plants near the house and other structures to discourage pests from establishing a foothold and gaining easy access.
  • Eliminate Clutter. Spiders seek out secluded, undisturbed areas where they can build a web to catch their next meal. Attics, crawl space and storage sheds are prime locations. Keep these areas clean and clutter-free and seal boxes with tape to prevent spiders from scampering inside.

The Signs of A Mouse in the House

rodents

With the fall season nearly upon us (fall officially arrives on September 22), rodents, particularly mice, become more active in seeking new sources of food, water and shelter in and around your home. Why is there a rodent “surge” this time of year?

Michigan’s dry, hot summer depleted many naturally occurring food and water sources and this causes rodents to explore their surroundings more aggressively in search of these necessities. And like humans, rodents also look for relief from the elements (i.e. heat) and associate cooler locations with water sources.

The house mouse is a curious creature and will readily explore your home using wall voids, utility pipes and wires, and heating and cooling ductwork to move around in search of their next meal. As a result, wall and cabinet voids near kitchen appliances (i.e. refrigerators, dishwashers, stoves, etc.) and pantries are common nesting sites for mice.

And mice are patient invaders that will wait for just the right opportunity – a door left propped open, being a stowaway in a box of off-season clothes brought in from a storage area, an open bag of pet food or a dime-sized opening in the foundation or door frame – to enter your home.

How do you know if you have a mouse problem? Some common signs of a possible rodent infestation include the following:

  • Rodent droppings (usually black in color and ¼ to ½ inch long) and urine (best detected using a black light)
  • Chewed electrical, computer or cable wiring (a major cause of electrical fires)
  • Unexplained chewing or gnaw marks on carpet, upholstery, drapes, furniture and baseboards
  • Chewed on food product packaging in your pantry

In addition to the kitchen, what areas of your home are most vulnerable to attracting an unwanted rodent infestation? Griffin Pest Solutions identified the following “rodent hot spots” in homes:

  • Attached garages and storage areas above these locations where storage boxes, pet food and other items are found
  • Bathroom cabinet voids
  • Utility rooms and areas beneath, and within base voids of furnaces, washers and clothes dryers
  • In wall, ceiling and floor voids
  • In the insulation of attics and in the contents of the attic (i.e. storage boxes)
  • In basements and crawlspaces near utility openings
  • Firewood stacked next to the house and near a door

Celebrate a Pest-Free Fourth of July

crawling insects

Can your Fourth of July be Pest-Free?  Your Fourth of July agenda usually includes picnics, cookouts, fireworks and good times with family and friends. It can also include an “explosion” of unwanted pests that want to spoil your good times.

When people gather for their holiday celebrations it is given there will be abundance of food and beverages available. However, your guests aren’t the only ones angling to fill up their plates! Pests are drawn to the sweet, sugary desserts, fruit and soft drinks that are a staple of holiday functions, as well as the greasy leftovers that can be found on grills, serving trays and garbage cans filled with post-party trash.

Griffin Pest Solutions wants you, your family and friends to have a safe, enjoyable Fourth of July and offers the following tips to keep annoying pests from spoiling your holiday fun.

  • Flies – Flies are a common interloper to almost any backyard cookout or picnic. Keep these filthy insects from spoiling your picnic by covering your food with foil or tight sealing lids or set up the buffet inside a screened in porch or tent. Also, remember to clean up food and beverage spills since they are a major attractant to flies.
  • Ants – Like flies, ants are drawn to food, and food spills and leftovers. Ants thrive on sweet, sugary substances like spilled soft drinks. Cleaning up spilled food and drinks, and rinsing out cans and bottles before they go into the recycle bin or garbage can will deny ants their sought after prize.
  • Stinging Insects – Nothing can ruin a party like getting stung by a bee or yellow jacket. Griffin Pest Solutions recommends homeowners inspect their property before the party for any signs of nests in trees or under awnings and the eaves of your home. Also, cover food and beverage cans/bottled since many stinging insects are attracted to sugary substances and no one wants to swallow a bee that flew into your beverage!
  • Mosquitoes – These nuisance pests are regular holiday party crashers and eliminating standing water and keeping vegetation trimmed in your yard are ways to prevent mosquitoes from nesting. Using insect repellent or yard sprays containing DEET or eucalyptus oil, lighting citronella candles or turning on a ceiling or box fan to literally blow mosquitoes away from your deck or patio (mosquitoes are not good flyers) are ways to toss these uninvited guests out.

Have a happy and safe, pest-free, Fourth of July!
