Understanding No-See-Ums

Commonly found in damp areas, grassy areas, and bodies of water, and especially thriving in humid areas or coastal regions, these biting insects are a nuisance. Known as biting midges, sand flies, or black flies, they are infamous for their itchy bites that rival those of mosquito bites.

Despite their small size, no-see-ums (sometimes referred to as see ums or see-ums) can cause quite an itch with their bites. In some coastal regions and places like South Florida, no see-um bites are a matter of daily annoyance. With their preference for blood meals derived from the blood of humans and animals, these insects can quickly turn an outdoor event into an itchy affair.

Prevention: The Best Way to Handle No-See-Ums

Prevent no-see-ums to avoid this!

Preventative measures are often the best way to handle a no-see-um problem. A vital part of this is making your yard unattractive to these biting insects. Since they breed in moist areas, the first thing you can do is eliminate all standing water sources in your yard.

This includes flower beds, ornamental plants, and any water bodies. Regularly pruning your plants, maintaining your lawn, and keeping a check on the organic matter in your yard can further deter these tiny insects.

The use of window screens and screen doors with small-mesh screens can be effective. The small size of the no-see um forces them to sneak through regular screens, hence the small-mesh screens would be your best bet.

Air conditioning is another great way of fending off these pests. No-see-ums aren’t big fans of cold temperatures, and a well-conditioned room can keep them at bay. Also, reducing the level of dark and damp areas can make your yard less inviting.

Inspect, Treat and Control: How To Get Rid Of Noseeums In Yard

While prevention is crucial, you may already be dealing with these biting midges. In such a case, inspection and treatment, followed by ongoing control efforts, are the most effective methods to handle the issue.


Noseeums are most active in the early morning and late afternoon.

Inspect your yard during these times to pinpoint the exact areas of infestation.

Pay close attention to moist areas and bodies of water where the life cycle of this pest begins as mosquito larvae.


After inspection, treatment of the affected area is the next step. Insect repellents containing active ingredients like lactic acid can offer temporary relief. You might also want to explore insect growth regulators for long-term control. These can stop the life cycle of these pests, preventing them from reaching their adult stages. Furthermore, you could apply insect control measures on a regular basis as a preventative measure.

Remember, a consistent approach is the key to gaining control over a see-um infestation. So, don’t hesitate to take the final step and reach out to professionals if necessary.

Frequently Asked Questions (FAQs)

What Kills No-See-Ums Instantly?

There are several insecticides and bug sprays that can kill no-see-ums instantly. These typically contain active ingredients like DEET, permethrin, or picaridin. However, remember to follow the product label and use them responsibly to minimize any potential harm to the environment or non-target species. Insect growth regulators can also be an effective solution in the long run as they stop the life cycle of these pests.

What Makes No-See-Ums Go Away?

Eliminating their preferred breeding sites is the best way to make no-see-ums go away. Practicing good yard hygiene is vital – regularly prune your plants, maintain your lawn, reduce the level of darkness and dampness in your yard, and remove any standing water or sources of moisture. Additionally, using repellents and keeping the air conditioner on (as cold temperatures deter these insects) can help keep them at bay.

What is the Best Deterrent for No-See-Ums In Your Yard?

There are various deterrents for no-see-ums available, including bug zappers, repellents, permethrin-based sprays, and electric swatters. Using window screens and screen doors with small-mesh screens can also prevent these small insects from entering your home. Remember, the best deterrent ultimately depends on your specific situation.

What Attracts No-See-Ums Bugs?

No-see-ums are attracted to carbon dioxide, lactic acid, body heat, and the dampness or humidity in the environment. They are especially drawn to areas with standing water or moist areas as these environments are ideal for laying eggs. Furthermore, warm body temperature and humid areas are attractive breeding grounds for these insects. If you reduce these aspects, you can reduce the likelihood of a no-see-um infestation.

Sidebar: Diving Deeper into the Life Cycle of No-See-Ums

Understanding the life cycle of no-see-ums can be crucial for their effective control and to learn how to get rid of noseeums in yard. These tiny pests go through four life stages: egg, larvae, pupa, and adult.

Egg Stage

The life cycle of a no-see-um starts off when a fertilized female lays her eggs in a moist area. Such locations could be damp soils, mud, or even bodies of water like marshes or lagoons. The female can lay hundreds of eggs at once, significantly increasing the future pest population.

Larval Stage

The eggs hatch into larvae after just a few days. During this stage, the larvae feed heavily on organic matter in their damp and moist surroundings. This can last for a period of 2 weeks to several months, depending significantly on the environmental conditions.

Pupal Stage

Following the larval stage, the developing no-see-ums enter a stage known as the pupa. Even though the insect does not feed during this stage, significant transformations from a larva to an adult occur. This is the shortest stage, usually taking just 2-3 days to complete.

Adult Stage

Finally, the now mature no-see-um emerges as a biting and flying adult insect. Interestingly, the adult stage is relatively short-lived, usually lasting only a few weeks. The females repeat the breeding process after taking a blood meal, thereby starting the life cycle anew.

By disrupting this lifecycle at any stage, we can limit the population of these pests in our outdoors space. Regularly removing standing water and managing the moist areas in your yard, can inhibit the ability for no-see-ums to lay eggs, effectively controlling their proliferation.


Living with no-see-ums can be a challenge. But with the right knowledge and tools, it is possible to reclaim and enjoy your outdoor spaces again. The comfortable, warm pool water or the cool breeze in your yard should not be haunted by painful, itchy bites. So, implement these methods and say goodbye to no-see-ums for good!
