Solar lights are extremely important for both indoor and outdoor for having a relaxing evening. But what if these lights attracted to bugs too? Would you enjoy the evening then? Well, if solar lights are attracted to bugs, then it might cause issues to your health. So, does solar light attract bugs? The answer mainly depends on the quality or spectrum of light. 

Therefore, depending on the light frequencies, it attracts the bugs. If the solar lights have a longer wavelength, then it will be less inviting for bugs and vice versa. Besides, some small insects are attracted to heat sources, so if you need to choose the solar lights that stay away from bugs, choose that produces less heat. In a nutshell, the light will be the thing to attract and keep away from bugs. Therefore, opting for the bulb with less heat is the best solution.

What are the best light bulbs with less heat?

As you know, using the right light bulbs can keep your home free from insects. So, with the help of the given table, you can understand the different light bulb and their heating capacity. Furthermore, we will understand the science behind the lights to attract bugs to solar light. Also, we will discuss the suitable remedies to avoid it and more. 

Look at the table below and make the right choice.

Why are bugs attracted to solar Lights? Know Science!

To understand the complete science behind why bugs are attracted to solar lights, we have investigated things in-depth and found two considerations of light that attracts bugs. These are heat and wavelength. Remember, here; the wavelength will be denoted as colour. 

So, let’s move ahead and know both aspects in detail. 

How the colour/wavelength attracts the bugs towards solar lights?

To understand the concept, let me clear that colour is just a range of wavelengths that run o a spectrum and produces different colours. On the science diagram, you will see wavelengths between 400nm to 780 nm, and insects can see a different portion of lights.  

Basically, insects can see only shorter wavelengths, so they feel more attracted to the Ultraviolet rays. This means they love to watch blue or red lights over the yellow bulb. This attraction to light can attract them to sit on solar lights. Sometimes, this biological response often gets confused when there are other sources of light within their view. 

How the heat attracts the bugs towards solar lights?

Besides lighting, many bugs get attracted to heat. Some insects look for warmth so they can feel comfortable. However, not all bugs are shaped in a way to get heat, as some like less heat or some sharp. In the scientific process, the heating insect’s terminology depends on insect thermoregulation. And let me clarify that if you for studies, you can find several theories on the same. 

Moreover, there is some type of insects that cannot generate their heat on their own while flying. On another side, these insects look for a source to get heat from the sun or solar lights. This is why you find some insects/bugs around the solar lights just to feel warm. 

Despite these, the other group of insects get attracted to heat because they want to hunt. With the use of infrared rays, they find their prey, and you are probably aware of these insects, mosquitoes.

What types of bugs are attracted to solar lights at night?

With the above conversation, we know that bugs are attracted to solar lights and even to carbon dioxide. Now, the question is, which bugs are attracted to the solar lights? 

If you check the phototaxis theory, you can easily know the relationship between the bugs with light. The negative phototaxis means the bug is repelled to the exposure of a light source. Thus, the few pests that fall in this category are cockroaches and earthworms. 

Besides, bugs that have come with positive responses are from flying insect’s families like a mosquito, butterflies, wasps, etc. These insects are either looking for a good source of light, food, or water. 

However, when you attract insects such as flies or moths, you will attract predators of flies. It means your blue-porch lights can attract the animals like birds, bats, and frogs. 

What are the types of light that do not attract bugs?

We know that heat is needed for bugs and insects to feel warmth during cool. We also got to know why bugs are attracted to solar lights. Moreover, we also know there are some heat-producing lights like halogen and incandescent builds that attract a major number of insects due to sharp rays of light. Now, we are coming to the main question of which type of lights do not attract bugs. 

For insects, UV lights are more preferable to them. However, they have fewer wavelengths that make them able to travel far. It means choosing the wrong light could turn your home into an insect home.  

Besides, the more blueish your light will be, it attracts a number of insects. For example, if the colour of light is light yellow, which is 2700k LED, it will be less attractive to insects, while if there is 6500k LED, it will give more blue rays, which is attractive to bugs/insects.

Keep note if you attract smaller bugs. Eventually, you call bugger bugs to have their free dinner. For example, mosquitos are most attracted to heat light, and they will attract big insects like a cockroach. Thus, your job is crucial, and you need to pick the right light to make things easy and keep the bugs away from the house. 

On this note, Edison string lights are 2700 K which are warm lights and create a cool ambience to sit in. Also, it is enough to lower the temperature, which is unattractive to insects. 

However, if you want to replace your lights with new ones, so read this post and choose the right bulbs for keeping your home bugs free.

How to prevent bugs attracted to solar lights?

If you do not want to change your budget, then using some preventive methods can help you save your house from bugs and insects. 

Try solar powered bugs zappers.

This is the most amazing offer to eliminate the bugs from home. These are powered by the sun, and you do not need to stress choosing batteries to change after weeks. Here are a few options to choose from. 

Besides, they are very portable and easy to use. This will catch your insects and keep the bugs away from home. Moreover, this will keep your home the attractive and best place to relax, as there will be no stress of insects that might attack you. 

Frequently Asked Questions

Q1. What kind of patio lights does not attract bugs?

Patio lights are also a good option to unattract the bugs to lights. These are also called handing lights or outdoor lights that transform your space quickly. Moreover, it gives a certain ambience that makes your space more cosy and relaxing. 

However, if you want to get started, you will need to assure several things such as placing of lights, type of patio lights to use, and how to hang them, so they don’t attract bugs.

Q2. What colour of outdoor lighting is good to keep bugs away?

Yellow and red lights are the best to keep away the bugs from home. Bugs are usually attracted to blue lights that cause spectrum lights. 

Q3. Do LED lights attract spiders?

LED lights are not like other bulbs; they are less attractive to spiders if you have noticed the presence of insects in the LED strips, so you must clean that area or use repellents to keep bugs away from the lights and from your home too.

The Bottom Line

With the above discussion, we hope you have found the answer that bugs are attracted to lights depending on their needs, the colour of light, and heat. However, be it LED, patio, or solar lights, bugs can be attracted to them but at a lesser pace than others.

Therefore to keep your lights clean and home with a cool ambience, one must use repellents to keep bugs away from lights. Besides, performing regular cleaning can help to have a good living. 

So, we hope you have found this post helpful, and it added great knowledge to your mind. If you have any queries to ask, drop them in the comments.
