How Can I Tell If I Have a Pest Infestation?

Signs You Have a Pest Infestation

Every pest infestation leaves behind some sign of the pest’s presence. Look for grime or other buildups on walls, smeared droppings, or bite damage on fabric and paper. See if you can smell strange odors in your basement, attic, or crawlspace. Check pest-prone areas consistently to look for changes.

If you can learn to identify pest infestations quickly, you can take action to remove them sooner. The sooner you can remove pest infestations, the lower the chance that they’ll do permanent damage… or spread. If you’re worried you have a pest infestation, look for any of the following four signs. The sooner you find evidence like this, the sooner you can take the next steps:

Grimy Buildup

Whatever pest infestation you have, they’re making a mess somewhere. Bugs, rodents, spiders, and beetles all prefer dark, enclosed, humid places, so start your search in the basement or attic. Look high-and-low, in corners, under furniture, along the edges of the walls, and near window frames. You might find grease stains, crumbs or other food remains, dirt smudges or even discarded hair.

Rodents, in particular, tend to familiarize themselves with set routes and then stick to them, so look for trails of grease or grime where their bodies may have rubbed off against the walls. If your floors or sills are dusty, look for trails left behind by pests moving around. Early signs like these are often subtle, so look closely, be patient, and believe yourself. It’s always better to be safe than sorry.

Droppings

It turns outs pests don’t practice great hygiene. There’s a reason they’re called “pests”, after all, and it isn’t because they’re fun to have around. Pests leave behind their waste just like everything else. Look for small droppings around the same pest-attractive areas you search for less conclusive evidence.

The type of dropping you may find will help you determine the kind of infestation you have. Rodent droppings are spindly or conical and solid. They’ll be small and may not look or smell like much of anything. Insect droppings are even smaller, but may also include shed or discarded skin, wings, or body parts. It’s tough to be a bug. Obviously, spiders make webs to catch prey. They tend to know their stuff when it comes to pest-catching, so anywhere you find webs, look for ways other pests may be getting in nearby.

Smells

Pests can produce a wide variety of smells, and pretty much all of them are unpleasant. All kinds of pests, including ants, beetles, rodents, or other bugs often carry off food to enjoy in a secluded place. The problem is, sometimes they don’t finish their meal and it begins to rot. If you smell rotting food and you can’t find it, it could be that a pest carried a piece of fruit into your walls.

Pests may also bite through food packaging in an attempt to get at its contents, breaking an airtight seal and exposing perishable foods. If you smell particularly foul odors, it’s possible that your pests are dying in their hiding places or walls and then rotting. Of course, their droppings often smell, too. If you’ve got a strange scent in your house that you can’t quite place, and it’s definitely not pleasant, an infestation could be the problem.

Fabric Damage

Unfortunately, moths aren’t the only pests who damage fabric and clothing. Different kinds of beetles, ants, rodents and bugs also feed on or at least chew through vulnerable fabric. Look for small holes or tears on clothing, drapes, carpeting, furniture, and any other fabric-based stuff you may have. It may not seem particularly appealing to us, but pests don’t mind the taste of underwear one bit.

When we say “fabric damage,” we don’t just mean bite marks, either. Like anything else they’re around, pests can make fabric dirty. Look for smudges of dirt, grease, grime, or droppings on your fabric. These dirty patches may be very small, but they could get big too. Look at freshly washed and dried clothing especially. See if your fresh laundry gets dirty or damaged before you even have a chance to wear it.

 

If you find any of these four signs during your inspection, give us a call. We’ll use the info you helpfully provide to figure exactly what kinds of pest infestation you’re dealing with, where they’re coming from, and how we can keep them out. We know we can take care of your problem quickly and effectively, because we’ve done it countless times before. Happy hunting!

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!

The Rats of Detroit and How to Stop Them

A recently conducted study found that Detroit is the Ninth most rat infested city in the US. Detroit’s rat population is on the rise.

Why are rat populations in Detroit becoming such a problem? Is there anything we can do to keep the population down, or least keep the rats out of our homes? Griffin wants to answer these questions, so you know where your rats might be coming from and what you can do about it.

Why Do Rats Love Detroit?

Like most pests, rats have simple needs and want to fulfill those needs as easily as possible. They flock to the parts of the world where the things they need are abundant, easily found, and as risk-free to pursue as possible. Cities like Detroit meet these criteria exceptionally well. Here’s what rats need, and how Detroit gives it to them:

Food

Most rats rarely wander further than their “home range” of 50 to 150 feet in any direction from the nest. Rats have poor eyesight, and prefer to know the environments they live in well to limit risk of predation or starvation.

A rat’s environment has to ensure that they can get enough food to survive while staying close to home. Cities solve this problem. High population densities create a lot of trash, which rats can use to feed themselves without ever leaving the nest. The next time you see a rat, check to see if there’s a dumpster nearby. Chances are, their nest isn’t far off.

Water

Just like pretty much everything else, rats need water to survive. Rats have to find a way to get a sustainable source of water close to their homes. It also has to be safe and relatively consistent, since rats are vulnerable while they drink. Cities solve this problem too.

Not only is there always a surplus of free water for rats somewhere, that water is often safe to linger around. Adult brown rats require only an ounce of water daily. Leaking pipes, broken valves, or condensation are more than enough to sustain them. Cities provide more chances to find water sources that can be accessed safely than any other environment would.

Shelter

The other thing all rats need to survive is warmth. When Winter comes, rat’s fur isn’t enough to protect them from freezing. They have to seek shelter in warm enclosures.

Cities provide for this need better than anywhere else, too. Old buildings, buildings that have fallen into disrepair, abandoned buildings, and unstaffed warehouses are all perfect places for rats to wait out the winter. They have all they can eat while they wait! The nooks and crannies of cities provide more safe shelter than anywhere else, and rats take advantage.

Keeping Them Out

Know that you know why rats are coming into your city, you can apply that knowledge to keeping them out. Rats go to places where they can easily get what they need. If you want to keep them away, you have to make sure they can’t.

Food

The most important way you can avoid attracting rats is by depriving them of food sources. Use tightly sealed, thick garbage bags to store and transport all your trash. Rinse out empty food containers before disposing of them. Keep your home’s garbage in a sealed container and keep it off the ground. Take your garbage out frequently, and make sure the dumpster you’re taking it out to is 15 feet or more away from your home.

Clean up your kitchen and dining surface immediately following each meal. Vacuum the rooms you eat in frequently and thoroughly. Make sure you put away groceries in their proper places. Don’t leave food out on the kitchen counter, especially not fruits or breads. Don’t leave snacks out after you’re finished with them, and don’t leave dishes in the kitchen sink.

Water

Once you’ve dealt with the food sources, look for places where rats could be getting water. Make sure you don’t have any leaking faucets, shower heads, or pipes. Invest in a humidifier for humid areas of your home. Look for drafts that could be letting air in. Make sure other water-based appliances like your dishwasher and refrigerator aren’t leaking either.

Finally, look for moisture. Make sure you’re always running your bathroom fan when bathing. Dry and put away dishes as soon as the dishwasher’s done with them. Rinse out bottles and cans before recycling them, even if almost all the liquid in the container is gone. Seal recyclables in bags and take it out frequently.

Shelter

Keeping food and water away will help, but if you really want to keep rats out, you have to make sure they have no way of getting in. Rats can squeeze through openings no larger than the size of a nickel, so don’t assume any cracks or gaps are rat-proof. Seal cracks in your foundation or walls with caulk. Replace worn weatherstripping, screens, and wooden frames. Make sure your windows and doors are properly sized and seated.

One of the most common places rats sneak in is around utility lines entering the building. Inspect that area and seal any gap you find between the lines and the house. Rats can also scurry up surprisingly steep surfaces such as trees to get on top of a house, so make sure your landscaping doesn’t create any likely paths to your roof. While you’re at it, try putting screens over your chimney and plumbing vent.

 

Remember: no matter how bad the rat problem, we can help you. We’ve been dealing with rats in Detroit and beyond for a long time, and we’re sure we can handle whatever they throw at us.

Protecting Your Trash From Hungry Pests

Careers with Rentokil  in Kalamazoo - Griffin Pest Solutions

You might be wondering why you should need to protect your trash bin from outdoor pests. Everything in it is garbage, after all. The problem is that after pests get used to eating garbage from your bin, they start to get bolder. Smaller pests like rodents and roaches will start looking for ways to get into your house, since they’re nearby anyway. Larger pests, like raccoons, will start to lose their fear of humans, which can be dangerous.

One of the best ways you can keep pests away from your home and property is by depriving them of an easy meal at your garbage bin. Follow these steps to make sure your bin is secured… so the only thing getting in and out of it is you.

 

black garbage bags

Only Throw Bags in Bin

It’s probably tempting to throw trash from your car directly into your bin when you get home, but it’s a bad idea. Loose garbage smells, attracting pests from near and far. It’s also a lot easier to get to and eat than food kept in a tied bag.

Throw any trash your home produces into bags before it goes out into the bin. The only thing that should go into your outdoor bin should be garbage bags. Make sure the garbage bags aren’t broken, and seal them tightly. If you only store bags in your bin, it’ll stay clean longer and won’t attract nearly as many pests.

 

bungee cords

Fasten Lid with Bungee Cord

Pests access your garbage bin by climbing up to the lid and squeezing under to get at the garbage inside. Pests can squeeze through tiny gaps, so if you’re going to secure your bin’s lid, you need to make sure it’s tightly and securely fastened down.

Make a chain of a couple bungee cords. Wrap them under and then over the bin from bottom-to-top, so that the pressure of the strain produced by the cords is weighing down on the lid of the trash can. Make sure there’s no slack in your bungee cord chain. If you made it tight enough, it should be impossible for any pests to open the lid and get into the bin. Unfasten the cord chain carefully before opening the lid yourself.

Rinsing out recycling

Rinse Liquids Out Before Disposing

Moisture, especially sugary moisture, attracts pests even more than easy food. Any trash that generates condensation or contains liquid will be like a beacon to thirsty pests.

Before disposing of recyclables like cans, bottles, or paper cups, make sure you rinse them out to get rid of any leftover fluid inside the receptacle. Do the same for any trash containing moisture, such as TV dinners or juice boxes. Dry the outside of the trash after rinsing.

 

Garbage and recycling bins sitting out on curb

Empty Once a Week

This one is obvious, but make sure your neighborhood’s garbage company empties your garbage and recycling bins once a week.

Check to make sure the garbage company is effectively collecting all of your trash. After their weekly collection, there should be nothing in your bin whatsoever. Make sure they aren’t letting any garbage fall out of the bin or truck to litter your property, either.

 

Hose spraying attachment

Wash Out Bin

Even if you only throw out sealed garbage bags, your bin will get dirty over time. Use your hose or a bucket of hot, sudsy water to rinse, wash, and re-rinse your garbage bin about once a month.

Scrape out any garbage residue and scrub down the inside and outside walls of the bin. Use dishwashing soap or another heavy-duty cleaning agent. Once you’re done, rinse out the inside and outside thoroughly. Repeat until your bin is totally clean.

 

Trash bins kept outside

Store Away From House

It’s a good idea to keep your outdoor garbage bin about 10 feet away from your house, even if it isn’t garbage day. That way, when pests come to check out the bin, they won’t associate it with your house and start to look for a way in.

This is especially important if your garbage bin smells, though regular cleaning should help remedy that problem.

 

Securing your garbage and recycling bins is a simple but effective way to keep pests out of your home and property. It’s also a good way to promote household hygiene awareness. If you can’t think about developing better pest-proofing habits until you’ve solved your current infestation problems, give Griffin a call today. We can make sure even the most frustrating of pests don’t trouble your home again.
