There are a great number of insect species inhabiting the earth, and people who frequent the great outdoors for work, fun, or play, are bound at some time or another to encounter one, many, or all of them. In an effort to make your outdoors experience more enjoyable, we have compiled a list of the most common insects you are likely to run into and what you need to know about them:


General Information:

Tiny, irritating blood suckers that not only feast on human blood, they are also quite fond of: mammals, birds, reptiles, amphibians, even some kinds of fish. Interestingly, mosquitoes use chemical, visual, and heat sensors to find their prey. While both males and females are known to feed on nectars and plants, the females are better equipped to feed on humans and the other species aforementioned. The intense itching and irritation one experiences after a mosquito bite is caused by the insect's saliva.

Diseases: Malaria, Yellow Fever, and most notably, West Nile Virus.

Habitat: Mosquitoes can be found throughout the United States, and often prefer areas with stagnant water (within which they lay their eggs) such as: ponds, marshes, swamps, and other wetland habitats.

How to Protect Yourself:

-          Avoid leaving windows and doors open during the warmer months.

-          Wear long sleeves and pants when outdoors during peak mosquito hours (dusk and dawn).

-          Do not leave standing water around your home (i.e. buckets, pools, etc.).

-          Replace exterior light bulbs with yellow bulbs as mosquitoes are less attracted to them.

-          Protect yourself with a trusted insect repellent such as 10 Hour Insect Repellent.


General Information:

Ticks are an ever-growing problem in the United States. There are a number of different species, all of which are equally capable of spreading harmful diseases. They are fond of both humans and our furry friends, particularly dogs.

Diseases: Rocky Mountain Spotted Fever & Lyme Disease.

Habitat: Wooded areas, tall brush/grass, under fallen leaves, under plants and ground cover in your yard, as well as around stone walls and wood piles.

How to Protect Yourself:

-          Utilize an insect repellent designed for use against ticks such as 10 Hour Insect Repellent.

-          Complete a full-body check when you come indoors after trekking through areas where ticks typically reside.

-          After a full-body check, shower immediately.

-          Place appropriate clothing and gear in the dryer on high heat for at least 30 minutes.


General Information:

Also known as berry bugs or red bugs, chiggers belong to a mite family of approximately 30 different species. Interestingly, chiggers only feast on humans during the larval stage. Bites cause red welts, coupled with intense itching typically found near the waist, ankles, and in warm skin folds. Once they've fed on their host, they drop to the ground and become nymphs, eventually maturing into adults. When they've reached adulthood, chiggers are no longer harmful to humans.

Diseases: Do not typically carry diseases in North America.

Habitat: Forests, grasslands, in vegetation of low, damp areas such as berry bushes, woodlands, orchards, along lakes and streams, even in lawns and parks.

How to Protect Yourself:

-          Use an insect repellent indicated for use against chiggers such as 10 Hour Insect Repellent.

-          If you plan to be outdoors for an extended period of time, wear long sleeves and pants.

-          Once you are back indoors, immediately take a hot shower and launder your clothing (preferably in warm/hot water, high heat in the dryer).


General Information:

Fire ants are so named for their reddish-brown appearance and their painful sting that will send you running for your mom (Just kidding… kind of). These nasty little critters look just like your standard black ants as far as size and shape are concerned, but ordinary, they are not! If threatened, fire ants bite (only for grip) then sting to inject alkaloid venom that causes a painful, burning sensation. Unlike many insects, fire ants do not hibernate, and are well known for their ability to survive extreme weather conditions.

Diseases: No known to carry any diseases.

Habitat: Prefer to build their mounds (or, hills) in open areas with access to lots of sunlight such as: meadows, pastures, parks, playgrounds, lawns, golf courses, as well as agricultural areas.

How to Protect Yourself:

-          Keep an eye out for ant hills or mounds & avoid them!

-          Wear shoes as often as possible when spending time outdoors.


General Information:

These tiny insects are so named for their microscopic size, they are nearly impossible to see at a whopping 1/16th of an inch. So small in fact, they could fit through a window screen! Similar to mosquitoes, only the females are equipped to bite and feed on blood. No-see-ums are a prominent issue during the warmer spring months when they begin breeding, needing blood meal to complete the reproductive cycle. This can last for several weeks. The bite of a no-see-um causes intensely-itchy red welts that can last for a week or more.

Diseases: Have the potential to spread protozoa and/or filarial worms in tropical regions.

Habitat: Found in almost any aquatic and semiaquatic habitat throughout the world. They can also be found in mountain ranges, beaches, and grassy areas.

How to Protect Yourself:

-          Avoid sitting directly on grass during the spring months.

-          Use an insect repellent indicated for use against no-see-ums such as 10 Hour Insect Repellent.

-          When you return indoors, immediately wash clothing in warm/hot water and dry on high heat.

-          Shower immediately after coming indoors.


General Information:

According to the Mayo Clinic, there are only a few spiders that pose a threat to humans. Two of which can be found throughout the U.S., although are more common in the southern states: the black widow spider, and the brown recluse. Bites from either spider can cause a number symptoms including: chills, fever, nausea & vomiting, and abdominal pain. If bitten, the May Clinic suggests:

-          Cleansing the wound with soap and water.

-          If bitten on the arm or leg, tie a bandage above the bite and elevate the affected limb to help stop the venom's spread.

-          Apply a cold compress to the bite.

-          Seek immediate medical attention. In some cases, treatment for a black widow or brown recluse bite may require anti-venom medication.

-          Shake off fire wood before coming indoors.

Diseases: Not known to carry diseases.

Habitat: Spiders prefer warm, dark, dry climates with plenty of food (flies) available. Undisturbed areas are a favorite including but not limited to: closets, woodpiles, sheds, corners in the garage, and under sinks.

How to Protect Yourself:

-          When working in areas that spiders typically reside, wear long sleeves, pants, and gloves.

-          Watch where you place your hands.

-          Shake off clothing before you put it on or go inside.

-          Sweep, mop, & vacuum webs and spiders regularly.

-          In storage areas avoid placing boxes directly against the wall, and keep them taped shut.

-          Keep clutter and growth clear around the home.

-          Routinely spray your home with products indicated for use against spiders.


General Information:

Hornets, wasps, & bees are a problem for most people who frequent the outdoors. In most cases a sting or a bite will cause mild pain and irritation. For some, it can cause a deadly allergic reaction. According to the CDC, an estimated 100 people die each year from allergic reactions to bee, wasp, and hornet stings. Individuals who are known to have such an allergy should carry a doctor prescribed epinephrine auto injector (EpiPen) at all times along with a medical signifier such as a bracelet, card, or necklace.

Diseases: Not known to carry any diseases.

Habitat: While found just about anywhere outdoors, they are particularly attracted to the pollen that flowers produce, therefore areas with flowering plants will host a significant number of these insects.

How to Protect Yourself:

-          Wear long sleeves and pants, preferably in light colors.

-          Sweat and oil can attract these insects, therefore showering daily and wearing clean clothes in important.

-          Clean up food as soon as possible after eating to avoid attracting them to you.

-          When attacked by hornets, wasps, or bees, relocate as soon as possible. Bees release a chemical that attracts fellow bees when they sting. Look for shaded areas, or an indoor location.
