What Are These Tiny Flying Bugs On My Window Sill?

Drain Flies

Drain flies are one of the common tiny flying bugs found on or in windowsills.

Drain flies, also known as sewer flies, can be seen any time of the year in the garden or around the house.

These flies are annoyances, as they bite people and animals, contaminate food and cause disease.

Flies may sneak inside electrical equipment, where they lay eggs and cause short circuits.

Drain flies enjoy moisture and damp places, so the pipes are their favorite nesting spots.

Drain flies like to hide in drains, toilets, garbage cans, garbage disposal units and sewers.

When the number of drain flies in your bathroom increases, it means that there is too much moisture there.

Drain flies have life span of about two months; however, the females can lay many eggs in a day.

Most of the time, drain fly adults fly alone; however, when you see batches of them flying around your kitchen, it means that they must have a nest somewhere close by.

Drain flies will feed off of decomposing organic matter.

They’re also frequent in medical sites where they feed on blood and moisture.

Drain flies live and reproduce in moist and dark areas.


Springtails are annoying tiny flying bugs that are found commonly in spring or fall.

They are busy all year and are most active during spring and fall.

Even in the winter, springtails may live in moist soil or decaying vegetation temperatures that are about 60 degrees Fahrenheit (15 degrees Celsius).

Springtails like damp and humid environments like basements and crawl spaces.

Springtails may be found in locations like mulch beds, organic debris piles and leaf litter for example.

They’ll enter your house through cracks and crevices of the foundation or through cracks of your window.

They’ll also get in via crawl-space vents and damaged window screens.

Springtails will seek for cool, moist and dark places in your home to settle in.

The springtails are also common in houseplants and soil-dwelling fungi.

As a result, they attempt to keep areas free from excess moisture and humidity through excreting large quantities of fecal matter.

If you shut the windows, they will enter through gaps and crevices.

Springtails will take advantage of cracks and gaps in your wall, door and window frames and doorsills.

Springtails do not bite, but they may be a nuisance when they crawl across you and your food.

Sewer flies

The sewer flies seem harmless at first, but soon you may start feeling itchy and irritated after coming in contact with these flies.

The character is unaware that the fly has contaminated them with its excretory waste.

While it’s unlikely that you’ll ever be in direct contact with these flies, they are still an annoyance as they congregate in dirty areas.

Window flies are drawn to them and often use them as a food source, so if you are dealing with sewer flies, then you’ll know that there is also quite a colony near your window.

Sewer flies frequently establish nests in municipal trash bins, garbage disposal units, septic tanks and sewers.

They enter your home through the kitchen and bathroom drains and pipes. However, these bugs can also get into your home through broken window screens and doorsills.

They may, however, readily track infections such as bacterial food poisoning and dysentery from unsanitary conditions on your body and around your home.


Gnats may be a nuisance when they swarm around your face and eyes.

Gnats, like springtails, can multiply quickly as they breed rapidly in warm and humid environments.

The gnats have the ability to hibernate all year long in dry, cool places under rocks, logs or soil.

When these tiny flying bugs are cold, they enter a state of torpor and survive even without food for 10 to 15 days.

This may happen even when they reproduce in swarms.

They deposit their eggs in moist soil during the spring and summer months and again during autumn and winter.

Gnats are little, black insects with a wingspan of about 1/8th of an inch.

During the gnats months, when they reproduce the most rapidly, their population can become explosive.

The extreme dryness outdoors forces these little insects to seek warmth and moisture indoors.

Gnats might also be referred to as fruit flies or vinegar flies because they feed on fermenting fruit and vinegar.

Gnats hidden in the plant or plant soil can cause diseases on the host plant.

What Attracts Tiny Flying Bugs To Enter Houses Through The Windowsills?


Most of the bugs that infest your home originate outside rather than enter through the doors or windows.

The weather becomes a major factor in determining which flying bugs will enter your home.

Different bugs like to breed in different climates and weather conditions.

If the weather outdoors becomes too hot, cold, wet or dry, some species of flying bugs will seek shelter in yours.

Overgrown Bushes and vegetation

Another factor to consider is whether or not you have any overgrown bushes or trees near your home.

Bugs like to breed in overgrown bushes or shrubs that grow near your home.

Even potted flowers near your house can be a source of infestations for tiny flying bugs. So, be careful about where you place potted plants near your home.

When tiny flying bugs enter into a home through window frames or doors, they like to find a nice dark corner that is sheltered from the wind where they can reproduce and lay eggs.

When this vegetation grows too large, it thickens up and provides cover for tiny flying bugs.

Bugs will enter your house through these overgrown bushes and shrubbery and fly into your home through the doors and windows.


These bugs, particularly those that fly, are attracted to light.

These annoyance bugs and bugs with the wings are attracted to lights in and around the house at night that shine through the cracks in the walls or windows.

Gnats, like moths, are attracted to lights at night.

Turn off any lights near the windows to prevent them from flying in through the cracks and attracting other tiny flying bugs inside of your home.

These bugs will not be lured to your windows if they know there is not a light source nearby.

Use Anti Bug Bulbs

The majority of the bugs that bite or sting are insects of some kind.

Because you can’t live in your house in the daytime and you can’t live in your house in the nighttime, you usually wind up sleeping outdoors in your yard (or in a tent) during the daytime.

Bugs are not attracted just to light, but to all sorts of other objects that emit light such as your car headlights when it sits outside and your back porch light at night.

You don’t have to live with these biting and stinging insects anymore since there are so many natural options to repel them from your yard.

Simply position them in areas such as yard lights and car headlights and watch them quickly leave your yard.


Citronella oil is one of the more popular choices for repelling biting and stinging insects naturally.

When dealing with citronella, you want strong citronella oil because weak citronella oil won’t repel the bugs anyway.

Wear rubber gloves to spray the citronella oil on your windows and doors, screens, and doors using an umbrella nozzle so that you don’t end up spraying a lot on your hands or clothes.

Using a paper towel, smear the citronella essential oil onto the surfaces you want to repel bugs from.

Seal The Cracks

Bugs may enter via cracks around windows and doors and entering the walls, so seal those cracks with caulking.

Use a good outdoor caulk on the exterior of your home.

It’s recommended to utilize an outdoor caulk to prevent water intrusion and harm to your home’s interior.

Silicone-based sealants are tough, can’t be easily removed, and withstand heat and cold.

Apple Cider Vinegar

Placing a small cup of apple cider vinegar on window ledges, window sills, and other entry points for bugs is another option to consider.

The aroma of apple cider vinegar is unpleasant to insects so they have no desire to enter your windows or home.

After they land in the apple cider vinegar and it gets on their skin or wings, they can’t fly very well and probably get killed by predators like birds, spiders, and lizards.

Don’t Overwater Your Yard and Don’t Overuse Fertilizers

Clover mites are attracted and prefer moist places so discourage them from entering your home by keeping the lawn and garden well-watered and not overusing fertilizers or pesticides.

Overwatering your lawn or garden encourages clover mites and other harmful insects to overpopulate and your plants also die due to the overabundance of fungus and bacteria.

A moist garden or yard is a perfect breeding ground for clover mites and other common household bugs.

Make certain that no garbage or other waste materials are left out around your home.

Using trash cans with lids will help prevent Clover mites and other household pests from gaining access to your food or other waste matter.

Another excellent preventive method to keep these gnats away is to install screen doors on some of the entrances to your home or business.

Trim Overgrown Bushes

These bugs use overgrown plants and foliage to shelter themselves and supplies food for them to eat and lay eggs in.

Trim down any overgrown bushes and shrubs near your home and be sure you keep the vegetation trimmed to a height of 4 inches or less.

The denser the vegetation around your house, the more shelter you provide for these tiny flying bugs.

Be sure to use a sharp gardening sheers to trim the bushes and shrubs.

That’s why, particularly if the vegetation is around your home’s foundation, you should consider trimming it down to a height of one foot or less.

Fix Water Leakages

Repair any water leakage problems immediately.

Water leaks cause your yard, driveway or swimming pool to flood after heavy rain storms.

The increased moisture will provide an environment in which these bugs will thrive and multiply in.

Moisture attracts bugs, particularly the flying variety to infest homes and yards.
