Bugs Hitting Window At Night [Causes & How To Avoid From Bugs?]

Opening the window to allow air in during the warmer months may also let pesky pests inside. But do not fret. You can use physical barriers or natural and chemical repellents to keep it open while keeping insects out.  In this article, we’ll go through the top ways to prevent Bugs Hitting Window At Night.

Bugs Hitting Window At Night

There are several causes of bugs attacking windows at night, including:

  1. Drawn To Light: Moths and other flying insects are among the many insects attracted to light. Inside houses or other structures, artificial lighting can be especially appealing. Insects may unintentionally hit surrounding windows or other glass surfaces while flying close to a light source.
  2. Problems With Nocturnal Insect Navigation: Some flies, and beetles use celestial landmarks like the moon or stars to find their way. Artificial lighting can interfere with their innate sense of direction, causing them to fly erratically and crash into windows.
  3. Reflections: Windows, particularly those well-lit from the inside, can serve as mirrors or reflected surfaces. Insects may attempt to fly through the mirror, thinking it is a clear path, which could lead to crashes.
  4. Heat And Moisture: Sources of heat and moisture draw insects. If indoor lighting or the temperature within the structure is higher than the outside, windows may emit heat at night. Insects may be drawn to the warmth, fly in its direction, and unintentionally strike the window.

To minimize insects hitting your windows at night, you can try the following:

  1. Close your curtains or blinds: By reducing the light that streams out of your windows, you can make them less alluring to insects.
  2. Dim or switch off lights when not in use to reduce the attraction of nocturnal insects. 2. switch off extra lights.
  3. Install window screens: Window screens can serve as a physical barrier to keep insects from getting to the surface of the window.
  4. Keep windows closed: By keeping your windows closed at night, you may considerably lower the likelihood that insects will enter your house and hit your windows.

Remember that some insects, like mosquitoes, may be more determined to get inside your house. In such circumstances, using insect screens or other mosquito prevention techniques can be advantageous.

What Are The Best Techniques To Stop Bugs From Peeping Through The Windows?

Insects can be very persistent in trying to enter our homes. The best strategies to prevent them from entering are listed below:

What Are The Best Techniques To Stop Bugs From Peeping Through The Windows

Insert Screens

Keeping your windows open is the best way for air to pass through your home. That is particularly true on warm summer nights.

But that time of year is also when some obtrusive pests are most active.

Mosquitoes take the top rank, but many more insects, such as ants, flies, and ticks, can get inside our homes. Installing screens on your windows is the greatest bug-proof solution. The best option is a stainless steel or fiberglass 2020 mesh screen.

This fine mesh, a no-see-um screen, has such small holes that no insects can squeeze through and enter your house.

Mesh screens have the advantage of being quick and simple to install using only common household tools. Additionally, you avoid using chemicals to keep the pests out, which is always a win in our book.

Just be aware that a mesh of this size is prone to tearing and piercing. A tiny hole can also allow obnoxious pests to wait outside to enter. Because of this, you should routinely check for holes or tears and fix them as soon as possible.

Use Aromatic Compounds

Some essential oils are produced from plants that insects have evolved to avoid. For instance, mosquitoes will rarely be flying over lavender fields.

It is yet to be established by research whether they don’t like the scent of lavender flowers or whether there are undiscovered chemicals that have some other detrimental effect on them. However, we do know that they try to avoid us.

A spray bottle with water and fragrant oils helps clean window frames. Depending on the scent potency of each essential oil, 15 drops in a small spray container is a good rule of thumb.

Alternatively, clean your window frame by soaking a cloth in the essential oil and water solution. Finally, you can put essential oils in a jar and place them on your window if it looks like bugs are too obstinate to give up.

The greatest essential oils for warding off insects include peppermint, thyme, rosemary, citronella, and oregano. These work on various insects, including roaches, spiders, and insects like flies and mosquitoes.

Plants That Repel Pests

Real plants can be displayed on your windows in place of essential oils. Most plants that deter pests are herbs, which are simple to grow in pots throughout the warmer months.

Globules that contain essential oils are the source of their enticing aroma. These globules evaporate the essential oils, transforming into vapor when the temperature is high.  Insects can’t abide by these odors and will steer clear of them whenever possible, even though they are typically quite comforting to people.

Basil, mint, chives, neem, thyme, and sage are pleasant pest-repelling herbs. You can also grow petunias, marigolds, dahlias, and narcissus to add some color.

Sprinkle Diatomaceous Earth

Diatomaceous earth is an additional excellent natural remedy for pesky bugs. This herbicide has been used in gardening for many years.

Don’t worry; it’s harmless to people and animals but extremely harmful to pesky insects. Diatomaceous earth is a white powder that resembles chalk and is created by grinding up ancient fossils. These minute particles have an almost razor-like sharpness.

These fragments puncture the respiratory systems of insects that breathe them in, causing them to suffocate and die.  Sprinkle some diatomaceous earth around the window frames to deter insects from landing on your windows. You can also sprinkle some dust on the potting soil if you have potted plants on your windowsills.

Furthermore, the diatomaceous earth poses no threat to bees. Since flowers often grow close to windows, you can apply them without risk.

It should be noted that employing diatomaceous earth requires interaction with bugs to function. It will be destroyed if any bug steps on it.

However, it would help if you mixed this strategy with the others on this list to deal with flying insects effectively.

Bring In Birds

Being surrounded by wild birds extends beyond simply being able to listen to their daily serenades. Numerous bird species can brighten your day and deter bugs from landing on your windows.

Several common species, including sparrows, bluebirds, woodpeckers, and robins, eat bothersome bugs that attempt to enter your home.

Bird feeders placed close to windows are the greatest approach to drawing birds. Nesting boxes are also a wonderful option because most birds only feel their young insects.

These arrangements will also assist you in getting rid of slugs and snails if you have a garden. One thing needs to be remembered. Keep going even if the birds appear immediately away.

Allow them a week or two to locate your birding location. The other birds will quickly arrive after the first one.

Use Adhesive Tape

You can take advantage of flies hanging on your windows even though you undoubtedly detest them. Transparent sticky tapes are now available for attaching to windows.

Additionally, those bothersome insects will become permanently trapped as they attempt to land on the window’s surface. Since they don’t contain any smelly or hazardous chemicals, you can use these tapes without worrying if you have pets.

Even if they aren’t covered in insects, remember that these tapes lose their stickiness over time, so you’ll eventually need to replace them.

However, it would help if you didn’t leave dead insects on the surface for an extended period since other insects will eat them.

Alter Your Lights

It is a well-known fact that light sources attract insects. But did you know that, from their perspective, not all lightbulbs are created equal?

Typically, only ultraviolet, blue, and green lights are visible to insects. Because of this, you can frequently see them circling bluish-white and bright-white bulbs. On the other hand, bugs are less drawn to yellow, orange, and even red lights.

Even though red light won’t give you much visibility at night, you may always change the color of your white lighting to something warmer that won’t draw as many insects.

In addition to color and brightness, heat also draws insects. For this reason, replace your incandescent and halogen lights with LED or fluorescent ones.

Display A Bug Zapper

Since we’re talking about lighting, particular lamps are made to entice and eliminate insects. These devices are bug zappers, emitting ultraviolet light and attracting insects.

However, as insects approach the light, they are electrocuted. Bug zappers are effective against most insects, but only sometimes with mosquitoes. These cunning insects rarely fall into the trap and successfully dodge it for unknown reasons.

This means a bug zapper should be used with other strategies from this list since it won’t eliminate pest problems.

Maintain A Fan Aimed At A Window

It makes sense that insects avoid flowing air, given their low mass. After all, when the wind is blowing, it’s doubtful that you’ll observe a swarm of mosquitoes.

Now, it might not be windy very often where you live. However, a fan can generate airflow and ward off pesky insects. Just set it up so it faces the window.

Eliminate Standing Water

Stalling water near your home serves as a welcome mat for mosquitoes, silverfish, beetles, and various other insects. We don’t just mean pools, ponds, and fountains when we say this.

Bugs are drawn to places like birdbaths, overwatered planters, and garden sprinklers. Unfortunately, eliminating those sources is the only method to eliminate insects that frequent nearby water supplies.


An open window is always an invitation to bugs. There are many alternatives to closing the window that you can utilize to prevent them from breaking into your house at night.

This post has discussed some of the top techniques for fending against Bugs Hitting Window At Night, including natural cures and do-it-yourself crafts. However, combining them all is the best option. z

Frequently Asked Questions

Why do bugs enter my house through my window?

Your window frame has cracks and holes where bugs can enter through. Therefore, if your windows are really old, it’s likely that pests are entering through cracks that need to be sealed. Try to find any crevices as you examine your windows. After that, seal the holes with caulk or another sealant.

If I leave my window open at night, would bugs come in?

Insects that fly at night are typically drawn to light. After all the lights are out, open the window. Purchase a fan or a cooling system. Spiders and insects don’t hang out at open windows waiting to enter.

What makes nighttime so bug-filled for me?

Numerous typical home pests become active at night. Pests that only attack at night include crickets, bed bugs, and house centipedes. To find food, mates, and sources of moisture, they venture out at night. Due to the much lower night temperatures, mosquitoes also become more active.

How are window bugs killed?

Most window cleaning products with ammonia should work if you have window sill pests. They are incredibly prevalent; you may already have some in your home. They both can kill insects, and their ammonia repels many pests, preventing their re-entry.
