The saying “small but terrible” seems to be a fitting description for no-see-ums. They are so small in size that they can pass through a screen door without you noticing it.
This may be due to the fact that most of these creatures only measure 3 millimeters in length. However, this does not mean that you have to take them for granted.
Despite their very tiny size, they have the capacity to cause painful bites that may be more excruciating than that of the mosquito.
Here are the effective techniques on how to get rid of no-see-ums:
- Clear the stagnant waters in your area.
- Keep your doors and windows closed, if possible.
- Place small mesh screens in your doors and windows.
- Turn on your air conditioning units.
- Use dehumidifiers indoors.
- Place insect-repelling herbs and spices indoors and outdoors.
- Use candles or fragrances containing essential oils.
- Apply natural or chemical insect sprays in your backyard.
- Maintain cleanliness of your indoor and outdoor areas.
Now that you have acquired valuable knowledge on how to get rid of no-see-ums, you may continue to orient yourself with these tiny insects by determining their nature, identifying characteristics, behavior, the health problems they bring, and other helpful strategies in keeping them away from your indoor or outdoor space.
What Are No-See-Ums?
No-see-ums are also known as biting midges or Ceratopogonidae. The family of the said insect has more or less 5,000 species, with 1,000 of them belonging only to the genus Colicoides.
They are endemic in almost all of the parts of the world, including the tropical, subtropical, coastal, and Caribbean regions. They have the capability to bite humans and the bites can progress into stinging and itchy, red lesions.
Other than that, they can also transmit illnesses such as Bluetongue disease, African horse sickness, and Epizootic hemorrhagic disease and pass on microorganisms like Mansonella nematodes and arboviruses.
Are No-See-Ums Mosquitoes?
No-see-ums are not necessarily mosquitoes. They are tiny insects belonging to the class Insecta, order Diptera, suborder Nematocera, infraorder Culicomorpha, superfamily Chironomoidea, family Ceratopogonidae.
However, they may be similar to mosquitoes in the sense that they can give itchy and painful bites to humans.
What Does No-See-Ums Look Like?
No-see-ums are typically ⅛ inch in length. They are gray in color and have two wings with a distinct colored pattern and a dense set of hairs. Their eyes are large in size and lie above a segmented antenna that houses the Johnston’s organ.
Also, their abdomen has nine segments that have smaller ends, while their thorax is slightly extended above the head. As to their mouthparts, they have a set of teeth that is specially designed for cutting and biting.
These are perfectly hinged on their mandibles that are somewhat stretched out and found in their proboscis.
Where Do No-See-Ums Live?
No-see-ums are generally found near bodies of water. They thrive in moist and swampy environments including ponds, marshes, lakes, and streams.
Also, they like to dwell in slow-moving and standing waters as they can freely move and glide over them. They are also present in cavities and gaps that are filled with water, such as tree holes or large basins and receptacles.
In some instances, there are species that can survive in brackish or salty waters.
Can No-See-Ums Live In Your Bed?
No-see-ums are unlikely to live in a bed. Their habitat is usually found in moist and damp places like streams, marshes, ponds, lakes, canals, and other areas where stagnant and slow-moving waters are abundant. A bed is far from these environments.
What Attracts No-See-Ums?
These small insects are greatly attracted to moisture and dampness. This is the reason why they are constantly found in slow-moving and stagnant waters.
Other than that, no-see-ums are also enticed by high levels of carbon dioxide and heat from humans which may imply an abundance of blood meal.
Lastly, they love the odor coming from people with increased lactic acid such as for overweight, pregnant, and physically active individuals.
How Long Do No-See-Ums Live?
The life cycle of no-see-ums is usually completed within two to six weeks, but in some cases, it may take up to a year.
However, this is not definite as it may depend on their species, environment, and breeding location. Thus, no-see-ums may live for at least six to seven weeks.
Do No-See-Ums Bite?
No-see-ums can bite humans. If they encounter people with increased levels of carbon dioxide, lactic acid, and heat, they will not hesitate to sting on them just to feed on their blood.
In general, only female no-see-ums have the ability to bite humans since they need it for the production of eggs. They do this habit during dusk or dawn but in some cases, they can also bite when the sun is out.
Their primary source of blood is mammals but they can also feed on the blood of reptiles, birds, and amphibians.
Can No-See-Ums Bite Through Clothes?
No-see-ums may bite through clothes. Thus, it is advisable to wear light-colored, loose, and insect-mesh garments in order to reduce their incidents of biting.
They are typically three millimeters in length so it is easy for them to penetrate through certain fabrics.
Can No-See-Ums Bites Make You Sick?
No-see-ums can also bring various forms of sickness. These are the following:
Biting midges from the genus Culicoides have known vectors of filarial worms from the genus Mansonella.
When an infected no-see-um makes a puncture on a host’s skin, they can pass on the larval stage of the said parasites which will then reside on the pleural or peritoneal cavities.
The Culicoides species can also endanger the health and safety of domestic and wild animals like sheep, antelopes, elks, deers, camels, goats, and buffaloes.
Once these creatures are bitten, they may experience fever, lethargy, loss of weight, vomiting, diarrhea, ulcerations, bleeding and cyanotic episodes, and abortion if they are pregnant.
African Horse Sickness
The primary victims of this disease include horses, donkeys, zebras, camels, and mules. When these animals are bitten by infected biting midges, they may experience cardiac and respiratory problems like fever, edema, difficulty in breathing, coughing, frothy respiratory discharges, and in worst cases, cardiac failure and death.
Epizootic Hemorrhagic Disease
It is a viral disease that mainly affects white-tailed deers. The symptoms of this illness begin to emerge after at least seven days which may include fever, swelling, weakness, loss of appetite, and swollen head, neck, and other body parts.
Do No-See-Ums Carry Zika?
It is unlikely for no-see-ums to carry Zika. The said virus is passed on to humans primarily through the bites of infected Aedes aegypti and Aedes albopictus mosquitoes.
How Long Do No-See-Ums Bites Last?
The effects of no-see-um bites may last for up to two weeks. Their bites may go unnoticed at first or may leave a small red dot. However, the redness and swelling may become larger for up to 1 to 2 inches in diameter. The itchiness and mild pain may persist for up to 14 days.
How to Treat No-See-Ums Bites?
The following are the best strategies in treating no-see-um bites:
Step 1: Wash the bitten areas with running water and mild antibacterial soap.
Step 2: Do not scratch the bitten area. Apply ice pack or cold water to the bitten area as it will help ease itchiness.
Step 3: Put topical products such as zinc or analgesic creams on the bitten area to reduce pain, swelling, and intense itching.
Step 4: Take oral antihistamine medications.
What Time of Day Do No-See-Ums Come Out?
No-see-ums can go out at any time of the day. However, they are the most active when it’s dusk time or dawn. This is the time where they are at the peak of biting and sucking for blood.
