Can That Bug Hurt Me?

Venomous Brown Recluse Spider

The first thing you probably think whenever you see a weird-looking bug is “can that thing hurt me?” That momentary feeling of fear never really goes away (take it from us). When you see an insect (or spider, or wasp, etc.), you’ll probably freak out for a second. That’s ok! But if you learn what you’re looking at, you can also stop freaking out a second later.

We want to help you stop freaking out (because isn’t that what pest control is for, in the end?). That’s why we’re categorizing the freakiest bugs (and spiders, and wasps…) according to how both how dangerous they are and how painful their bites or stings are. Hopefully after reading this, you won’t feel quite as scared by the whatever-it-is you see on your porch. Well… after a second, at least.

Spiders

There are two medically-significant spiders in Michigan: the northern black widow (Latrodectus variolus) and the brown recluse (Loxosceles reclusa). These two spiders are venomous, and their bites are considered very dangerous. Northern black widow spiders are black with a prominent red, hourglass-shaped marking their abdomens. Brown recluse spiders are a uniform tan color with a darker, violin-shaped marking behind their heads. Northern black widows are native to Michigan and relatively common. Brown recluses are not.

Various other Michigan spider species may bite, but those bites are not serious and certainly not life-threatening. Black widow and brown recluse spiders are very rare, and even when they happen they are often not serious. These two spiders are both very shy by nature, and would always rather avoid conflict than lash out. If you see a northern black widow or brown recluse, keep your distance and remain calm. They will not hurt you unless they’re provoked.

The verdict:

Dangerous–YES, but it’s very unlikely.

Painful–YES, but, again, only if they bite you–which is very unlikely.

Fire ants can be threatening because they have a stinger and occasionally use it on people

Ants

There are thousands of species of ants living in Michigan. Though some of Michigan’s ants (such as carpenter ants) are major nuisance pests, very few are dangerous. Even the flying ants that occasionally seem to swarm around structures aggressively won’t attack people. In fact, most ants lack the capability to attack humans, even if they wanted to (and they don’t). There are two ants that could potentially harm you if you encounter them: Fire ants and Velvet “ants.”

Fire ants are distributed in the southern US, but they are inconsistently reported in Michigan. These small, brown-red ants can be threatening because they have a stinger and occasionally use it on people. Fire ant stings contain a venom that may affect the nervous system or prompt an allergic reaction. Stings aren’t usually serious, but if one person is stung numerous times or has an intense allergic reaction they could be. Velvet ants aren’t actually an ant at all; they’re a species of wasp. Speaking of…

The verdict:

Dangerous–NO, except in very specific circumstances.

Painful–YES. A fire ant’s sting is about as painful as a common wasp’s.

Wasps

There are several species and subspecies of wasp and yellowjacket in Michigan. The most common wasps are the common paper wasp and european paper wasp. There are twelve species of yellow jacket in Michigan, including German yellow jackets, Eastern yellow jackets, and Baldfaced hornets. These wasps and hornets tend to resemble “classic” wasps as you’d recognize them. They have yellow-and-black striping, hard, almost metallic-looking bodies, and translucent wings. The bald faced hornet tends to have pale or white striping instead but otherwise looks similar.

Wasps are territorial and capable of delivering numerous painful stings, but these stings aren’t medically dangerous unless you’re allergic. In most cases, you shouldn’t be afraid of wasps, but you should remain aware of them. Wasps may also make nests near your property. Wasp nests are made of various plant debris stuck together and hung from awnings or rafters. Wasps may defend their nests rather aggressively. If you see a wasp’s nest near your home, do not approach it. Bee and wasp nest removal can be dangerous and should only be conducted by  professionals.

The verdict:

Dangerous–NO, unless you’re allergic.

Painful–YES, wasp stings can be very painful, especially if they sting you multiple times.

Ticks

Unfortunately, ticks are very common in Michigan, especially in rural or forested areas. Ticks are most common during the summer, but they’re active in the spring and fall, as well. The most common Michigan ticks are the American dog tick, Blacklegged tick, lone star tick, and brown dog tick. Ticks feed on blood and find hosts by climbing bushes and then latching onto passerby. They feed by attaching to people and sucking blood for several hours.

Tick bites don’t generally hurt, though they may itch. Unfortunately, however, ticks are still probably the most legitimately dangerous pest on this list. Ticks can host and transmit several serious diseases to humans. The Blacklegged tick is one of the primary transmitters of lyme disease in Michigan. These ticks may also transmit Rocky Mountain spotted fever, tularemia, and more. Ticks don’t transmit a disease unless they’re attached to a host for 24 hours or more. If you find a tick on your body, remove it immediately.

The verdict:

Dangerous–YES. Although tickborne diseases are rare in Michigan, they are quite serious.

Painful–NO. You might not even notice a tick bite, which is part of the problem.

 

We may not ever “cure” your fear of creepy-crawlies, but hopefully this provided some context. While there are dangerous pests in Michigan, there’s also plenty you can do to prevent them from hurting you. Now that you know what to look for, you know what to avoid and when to get help.
We’re happy to be that happy, should you ever need it. If you have a pest problem, dangerous or otherwise, give Griffin a call anytime. We’ll help you stop freaking out–it’s what we do.

What Are The Most Dangerous Pests in Michigan?

The most dangerous pests in Michigan

Unfortunately, Michigan is home to several pests that can be quite dangerous. Some, like the black widow spider, are dangerous because of their venom. Others, like the Blacklegged tick, are dangerous because of diseases they can transmit. No matter why these pests are dangerous, however, you’ll want to keep away from them.

Ironically, the best way to keep away from dangerous pests in Michigan is to learn a thing or two about them. If you can reliably identify Michigan’s biggest baddies, you can take important steps to stay safe from them. Here’s what you should know about Michigan’s four most dangerous pests:

black widow spider

Black Widow

The Northern black widow spider’s habitat ranges throughout the eastern and central US. Michigan’s trees and prey make it the ideal environment for the poisonous spider to thrive in. Northern black widows are inch-and-a-half long, black spiders with a red “hour glass” marking on the back of their abdomens. The spider is common around Michigan’s lower peninsula, especially in the Southwest.  

While it’s true that they are common in Michigan, widow bites are quite rare. Black widows are timid and only bite if their web is threatened. Widows build their webs anywhere they can catch prey. They’re most commonly found in dark, damp locations like old stumps, hollow logs, fence posts, sheds, crawlspaces, basements, and woodpiles. Symptoms of black widow bites appear after 30 to 60 minutes and include muscle spasms, chills, nausea, fever, sweating, aches and pain, and headaches. If you’re bitten by a black widow, seek medical help immediately.

brown recluse spider

Brown Recluse Spider

The brown recluse is a poisonous spider native to the Southeast US. Experts traditionally believed that Michigan winters keep brown recluses out. However, from 2011 to 2017, six populations of brown recluse spiders have been identified in Michigan. The most recent population in Davison, Genesee County, lived in an unheated, detached garage. The fact that they lived through the winter in an unheated environment may imply that they can establish themselves in Michigan permanently.   

Recluses are around 6 to 20 millimeters long and tan or dark brown. They have a dark, violin-shaped mark on their thorax, or the back upper torso. Brown recluses seek out warmth and dampness and are usually found in rotting wood or cardboard. Brown recluse bites can rarely cause potentially life-threatening necrosis, or flesh death. If you think you’ve spotted or been bitten by a brown recluse, let the experts know right away.

Blacklegged Tick

The Ixodes scapularis, aka the “blacklegged” or “deer” tick, is one of three hard ticks commonly found in Michigan. Blacklegged ticks are most common in Western Michigan, but you could find them in any grassy area. Blacklegged ticks are small brown ticks with distinctive black legs (hence their common name). Like all ticks, Blacklegged ticks hunt or “quest” by perching on plant life and clinging to passing prey. This tick species primarily feed on humans during summer months.

Blacklegged ticks are the primary transmitters of Lyme disease in the North-central US. Blacklegged ticks pick up the disease-causing Borrelia burgdorferi bacteria when they feed on deer. Then, when they feed on a human, they transmit the bacteria into that human’s bloodstream. Lyme disease causes fevers, headaches, fatigue, and an expanding rash called Erythema migrans. Avoid tick bites by applying repellent when walking outside and staying out of grassy areas. Remove any ticks that attach themselves to you right away.

Mosquitoes

You know what mosquitoes are. Everyone knows what mosquitoes are, especially here in Michigan. Yes, of course they’re annoying… but are they really dangerous? Unfortunately, mosquitoes are dangerous because they carry and transmit various diseases. Worldwide, mosquitoes are among the most important and deadly disease transmitters. In Michigan, some species of mosquito may spread the West Nile virus. Mosquitoes pick up the disease when they feed on birds. They spread it via blood contact when they feed on humans.

80% of people afflicted with the West Nile virus never show any symptoms. For about 19% of people, West Nile triggers fevers, headaches, vomiting, and a rash. In less than 1% of cases, West Nile also triggers encephalitis or meningitis. Both of these inflammatory disorders are very serious and could have permanent or fatal effects. The best way to avoid West Nile virus is to avoid mosquito stings. Always wear repellent when walking outside and avoid mosquito breeding environments.

 

Hopefully we haven’t made you afraid to live in your own state! While it’s true that we’ve got some dangerous pests up here, they’re all more afraid of you than you are of them. By learning to identify pests like these and staying out of their way, you shouldn’t have anything to worry about.

And, of course, if you do end up confronting dangerous pests in your home, you can give us a call anytime. Michigan’s big bads have nothing on us!
