Michigan’s Summer Bug Blues

If summer ever feels too good to be true, then consider summer bugs the catch. All kinds of bugs naturally grow and thrive in the heat and abundance. Add Michigan’s seasonal humidity to that mix, and you have a pest paradise. Paradise for these pests, specifically.

These are four of the pests that Michigan will have the most trouble with this summer. Here’s why these pests love summer, what they’re up to, and how to keep them away from you.


mosquitoesWhen you think “summer bugs,” you almost certainly think of mosquitoes first and foremost. It’s not hard to understand why. There are over fifty mosquito species in Michigan, and they’re more-or-less all very active in summer. Lucky us. Some mosquito species start reproducing in spring. They lay eggs in puddles and other sources of “spring water” left behind by melting snow and rainfall. In general, the more standing water they have access to, the greater the mosquito population will be in summer.

Unfortunately, many mosquito species don’t stop reproducing in summer. Mosquito larvae grow faster in hot weather, so they’ll mature quickly, reproduce, and begin the cycle yet again. Mosquitoes thrive during hot, humid, and wet summers. You can’t really keep mosquitoes from thriving, but you can keep them away from you. Clean up sources of standing water near or inside your home. Make sure your window screens and frames seat properly. Address sources of excess humidity such as plumbing leaks or drafts.

Japanese Beetles

Japanese beetlesJapanese beetles are an invasive species that can inflict serious damage on lawns, turf, and ornamental plants. Their grubs feed on the roots of grass, and adults eat foliage. Both grub and adult feeding habits may interfere with your plant’s ability to withstand the hot weather of summer. Larval Japanese beetles hibernate underground during winter. During spring, they begin eating roots until they store enough energy to pupate. By late June or early July pupation completes and the beetles emerge from the ground as adults.

Adult Japanese beetles are a particular problem for a couple reasons. First, they often skeletonize the foliage of the plants they feed on. Next, they produce a pheromone that attracts other beetles to plants. They also tend to reproduce and lay eggs near where they eat. That means if you have beetles this year, you’ll probably have them next year, too. If you see beetles on your plants this summer, spray them with soapy water to scare them off. The soap will also counteract the pheromone, so new beetles won’t replace the ones you sprayed away.


waspsWasp queens become active in late spring, when temperatures rise to a consistently hospitable temperature. During early-to-mid summer, wasps largely remain near their nests. Workers leave to hunt for food every day to bring food back to support wasp larvae. Wasps are highly defensive of their nests while larvae develop inside them. The majority of wasp stings in mid summer occur when people accidentally disturb a nest.

By late summer, wasp queens will finish laying eggs, and the colony’s behavior will change. The year’s final brood grow into the next generation of wasp kings and queens. Once they leave the nest, the workers no longer have to worry about feeding and fostering young. Instead, they range further and spend their time hunting and eating. They tend to sting more people during this stage, especially if people startle them near their food. If you you have a wasp’s nest on your property, have a professional remove it as soon as possible.


House fliesSeveral types of common flies thrive and proliferate in summer. These flies are sometimes called “filth flies,” because they’re attracted to rotting garbage and waste. Filth flies like the house fly seem so abundant in summer because they spend the whole season reproducing. These flies complete their entire life cycle in only seven to 14 days. A single summer season may see literally hundreds of generations of filth flies born.

Fly infestations begin when flies find a place to lay their eggs indoors. House flies lay batches of 75 to 100 eggs at a time. Flies look for secluded, dirty places to lay their eggs. Usually, they find garbage, either in the dumpster or in cans. They may also infest clogged garbage disposals. Make sure your garbage is as sanitary and inaccessible as possible. Keep all garbage in sealable plastic bags, preferably inside sealed bins. Take garbage out to your dumpster frequently. Don’t let garbage pile up, either inside or in your dumpster.


No matter how inescapable they seem, you shouldn’t have to suffer bugs like these this summer. Following these steps will help you protect yourself from summer bugs, no matter how many assail you.

Waterborne Pests and How to Avoid Them

Here in the upper Midwest, we don’t get too much beach time. Even if you live on a lake, you probably can’t get out on the water nearly as much as you’d like. To make matters worse, when the water finally gets warm enough to enjoy, waterborne pests are all-too happy to enjoy it with you.

Running into a pest outside or in your home is bad enough. Running into one in your water is the worst. Knowing how to avoid and prevent water pests from infesting your home will help give you peace of mind, so you can get back to enjoying your precious beach time.




Mayflies get their name from their explosive emergence in May. They spend most of their lives as nymphs living in fresh water. Nymphs range in size from 3 to 30 millimeters (or .12 to 1.18 inches). They have six clawed legs, a slim body, gills, and two or three tails. Adult mayflies have famously short lifespans and live only to reproduce. They grow longer and more slender than nymphs, and their two pairs of pale wings become functional.

During mating season, mayflies swarm in huge numbers. Often, these swarms grow so large that they cover every surface in a wide area or create significant visibility issues for drivers. Mayflies are attracted to white incandescent and fluorescent lights. Replace white outdoor lighting with yellow bulbs. Consider drawing the blinds at night. If your mayfly problem seems particularly bad, UV light insect traps may prove effective.


mosquito on water


Yes, mosquitoes live in and around water. It’s just not fair! Specifically, many types of mosquito lay eggs in standing water. Mosquitoes need to stay hydrated to survive, which means they need to stay in places where the air is humid and damp. Both of these needs make lakes, rivers, and wetlands the perfect place for mosquitoes to live and breed. If they can get some of the blood they need to lay eggs somewhere nearby, so much the better.

The best way to prevent mosquito infestation in your home is to mop up standing water in your house or on your lawn. If you’re going out to the beach, bring some waterproof bug spray and reapply it every two hours. Try not to stay until dusk, when mosquitoes become more active. Bring along long sleeves and pants to change into after you’ve finished swimming.

Like most of the other pests on this list, cockroaches love moisture and humidity. Cockroaches can survive for a month without food, but only two weeks without water. Unfortunate beach goers commonly discover them under wet soil, clinging to the base of a tree or other plants. Though they rarely go near the water itself, the environment lakes and rivers create is perfect for roaches to thrive in.

Roaches are scavengers, and they’ll eat anything they can get their hands on. They’re especially fond of bread crumbs, rotting fruit, and sweets. Outdoor picnics will tend to attract them in droves, especially if remains are left behind. At home, securely tie off or box up your pantry foods and wipe down counters and tables after meals. Cockroaches will take pretty much whatever they can get, so do your best to give them nothing.


giant waterbug


Waterbugs are often mistaken for cockroaches, but there are some big differences–literally! First and foremost, size: waterbugs are a lot bigger than cockroaches. Lethocerus americanus, the most common waterbug in North America, ranges from 12 to 65 millimeters in length (1-2 inches long!). Unlike cockroaches, waterbugs actually live in water, swimming beneath the surface to catch prey. Cockroaches never bite humans, but water bugs are called “toe biters” because of their propensity to defend themselves with painful bites if disturbed.

Waterbugs need water. If they’re coming into your home, there’s a source available to them. Search your home for leaks, dripping faucets, or cracks that allow water in. Water bugs also fly toward light. These bugs get more active at night, when they fly around looking for new ponds or prospective mates. When you’re out, avoid spending too much time around lakes after dark, and be aware of where you step on the lake floor.


No two ways about it: water pests are freaky. No one wants to think about going for a swim, only to step on some gross bottom feeder. If you know a bit about the pests you’re likely to see, however, chances are they won’t seem as monstrous or dangerous to you. If you follow these steps, you may not have to see them at all!

If you’ve been struggling to keep waterborne pests out of your home or lawn for awhile and you’re at your wit’s end, give Griffin a call today! Whether they come by land, water, or air, we’ve got the perfect defense to thwart your pesky pillagers. Enjoy the beach!
