Mosquitoes and mosquito bites are undoubtedly disturbing things. Whenever it comes to repelling mosquitoes from your home, you might have tried different processes.

But most processes are not fully efficient. Moreover, some processes are toxic. So, many people use screens to keep mosquitoes out of the houses.

That’s why you might be confused about whether mosquitoes can get through screens or not. Screens also have different types.

So, you have to know details about the screens and the effectiveness of screens. Moreover, knowing the process of applying screens is also important.

Can mosquitoes get through screens?

Mosquitoes can get through screens if the mesh size of screens is large. Generally, screen perforations should be small enough to prevent mosquitoes. Besides, mosquitoes don’t crawl around the screens. But if the perforations are large and mosquitoes are small, they will enter through it.

However, screens can be of different types. Moreover, we install screens in different places of our houses. So, we have to know the effectiveness of those screens. Let’s see whether mosquitoes can get through different screens or not.

Screen doors:

Screen doors are meshed doors that contain many perforations to pass air. These screens are installed all over the door like another door.

So, when we install screen doors, they will pass air through the holes. But the meshes will prevent mosquitoes to enter the room.

But whether mosquitoes will get through the screen doors or not depends on the size of the meshes. If the size of the hole in the screen door is larger than the size of mosquitoes, it will let the mosquitoes in.

Sometimes, small mosquitoes can enter through the small size holes. But most of the time, small-mesh size screen doors will prevent the mosquitoes to enter.

Fly screens:

Generally, fly screens are used on windows to prevent mosquitoes. If you want to prevent mosquitoes from entering through the window, you need to install a fly screen that has small perforations.

Flyscreens are specially made with small mesh sizes. Even the holes are so small that mosquitoes will not able to pass them. But if there is a gap at the bottom of the screen, mosquitoes might enter through the gap.

So, if the fly screen is installed without a gap, mosquitoes can’t get through it. Moreover, air passing will be possible easily.

Window screens:

One of the main reasons for installing window screens is to be safe from mosquitoes. Because window screens have pretty small perforations. Generally, normal-sized mosquitoes can’t get through window screens.

Sometimes, window screens have gaps at the bottom or the size of the windows. Mosquitoes can enter through those gaps. So, whenever it comes to choosing screens for windows, make sure that the screens have small holes.

Otherwise, large holes will allow mosquitoes to enter through them.

Do screens keep out mosquitoes?

Yes, screens keep out mosquitoes. But the screens should have small holes in them. Generally, screens are widely used throughout the world to keep mosquitoes out. Most of the time, screens work well to keep out mosquitoes.

Many types of mosquito repellents are available. But some of them are highly toxic to the environment. Some of them create huge fume that is not environmentally safe. So, it will be wise to install screens.

Generally, mosquitoes enter our houses through windows and doors. So, screens are also available for doors and windows. Moreover, fly screens are specially made for keeping out mosquitoes.

But if the holes are large in the screens, mosquitoes might be able to get through them. So, choose small hole screens to keep out mosquitoes. Otherwise, you might not be safe from mosquitoes even after installing screens.

How do mosquitoes get through screens?

Generally, screens are helpful to keep out mosquitoes. But still, mosquitoes might be able to come inside your house through screens. For example, if the screens have gaps at the bottom of the window or door, mosquitoes might get through the gaps.

Moreover, sometimes, the holes are large enough for mosquitoes to get through the screens. For example, you might install grill-type screens to access more air-passing. But ultimately, it will let the mosquitoes come inside.

Generally, mosquitoes are not that clever to crawl into the holes of screens. But sometimes, they might be able to enter randomly if the holes are large. Sometimes, the size of mosquitoes is so small that they might pass through the screens.

If the mesh size is small enough and there is no gap at the bottom, mosquitoes can’t get through screens. But still, small mosquitoes might be able to enter randomly. Otherwise, you have to check if there is a gap or large hole in the mesh.

How small of a screen hole can a mosquito fit through?

Generally, a mosquito can’t fit through a hole less than 1 centimeter. Sometimes, holes are large and allow mosquitoes to fit through the screen holes. So, the size of screen holes is pretty important.

If you want to install screens in your doors and windows, you need to install perfect mesh size screens. You might be thinking that mosquitoes can even be smaller than 1 centimeter.

But this is a unique characteristic that mosquitoes are unable to pass through a hole less than 1 centimeter.

So, you have to choose the size carefully. If you install screens that have larger holes than 1 centimeter, mosquitoes might fit through the screens.

What kind of screen keeps mosquitoes out?

Screens can be of different types. For example, you can classify screens according to their manufacturing materials, sizes, and where you are using the screens.

So, you have to know which screens will be better to keep mosquitoes out. Let’s see about different types of screens.

Small mesh screen:

One of the most important features of an effective screen is the size of holes in the screen. The small the size of the holes, the more effective the screen is.

For example, if you install a screen that has a mesh size of less than 10 millimeters, it will be effective to keep mosquitoes out.

Double-layer screen:

The double-layer screen is another effective screen that will keep mosquitoes out. Generally, single layer screen has small perforations. But still, when you apply a double layer screen, it will provide more protection.

You might have known from the name that this type of screen has two layers. Even if the screen has large holes, the double layer will act as an obstacle for mosquitoes. So, a double-layer screen can keep mosquitoes away.

Privacy screen:

The privacy screen is a multifunctional screen. Generally, we use a privacy screen to keep out rooms visually unable to see through.

But it can also keep mosquitoes out. Because privacy screens have small holes that let fresh air come inside but prevent mosquitoes to come inside.

How do you keep mosquitoes out of screens?

Now that you know screens might be ineffective to keep mosquitoes out sometimes, you might want to know how you can keep mosquitoes out of screens. Knowing the appropriate way is essential. So, let’s see how you can keep mosquitoes out of screens.

Installing a small mesh screen:

If you want a non-toxic and environment-friendly way to keep mosquitoes out, you have to install a small mesh screen.

The size of the mesh plays an excellent role. It has been found that a mesh size from 3 to 6 millimeters is effective to keep mosquitoes out. Moreover, any size less than 20 millimeters is effective.

Using Citronella oil:

If you notice that mosquitoes are still roaming around the screens of windows or doors, you can use citronella oil. Sometimes, mosquitoes are able to enter through the screen whatever the mesh size is.

So, you can pour a little bit of oil into a tissue or paper towel and wipe the screen. This oil will keep mosquitoes out from the screen.

Repairing the gaps:

Sometimes, the screens of windows or doors might have gaps at the side or bottom. These gaps allow mosquitoes to enter through them. Moreover, when mosquitoes get a chance to enter through the gaps, they will stick to the screens.

So, you can repair the gaps of the screens and keep mosquitoes out of the screens.

Final Thoughts

Mosquitoes can’t get through screens if the holes of screens are small enough. For example, if the holes are less than 10 centimeters, mosquitoes will not enter through the holes. But if the holes are large, mosquitoes will come inside. So, it depends on the size of the mesh or holes of screens.
