Are Fleas Attracted to Light?
Although fleas are nocturnal creatures, they are indeed attracted to light. Fleas are active during the night, but when they are searching for food, light and heat attracts them.
Studies have shown that fleas move to lighted areas in the span of 30 to 40 minutes when a light source is placed in a dark area. Light also gives off heat and this is another reason why fleas are attracted to it.
Using light as an effective technique to attract and trap fleas has been proven to work and you should give it a try as well.
Can You See Fleas With UV Light?

The UV-light should be able to make fleas highly visible because their bodies absorb it. When the light surrounding the area is dim, the use of UV light shining in the area where you suspect fleas will make them more visible.
Are Fleas Attracted to Phone Light?
Fleas like green-yellow light at 500-530 nm. They are not attracted to red light above 600 nm. Fleas make consider the light on your flashlight casting a shadow against an object to be potential prey. They may decide to jump on your phone to inspect the area for a host.
The carbon dioxide that you breathe out while turning on your phone’s light may help to attract fleas to it. Another technique is to flicker your phone’s flashlight on and off to create or mimic movement.
Fleas are sensitive to lights turning on and off and the heat that results from it. A phone flashlight is not the best method of attracting please.
Are Fleas Attracted to UV Light?
Just like many other creepy crawlers, these tiny jumping insects have an affinity for UV light, flocking toward it when they see it.
That’s the reason why many bug zappers have feature glowing UV light, used as a way to attract all kinds of insects and zap them so they aren’t swarming around you anymore.
Adding a UV light outside of your bed, tent, or sleeping bag could be a way to prevent fleas from hopping over to you and your sleeping area while you nap.
If you’re in a place where fleas are prevalent and are trying to find an effective way to get and keep them away, UV light could be the way to go. Keep in mind that fleas will only flock to UV light if they:
- Have a sufficient amount of food
- Are not in favorable conditions
- Are close enough to UV light to be able to sense and see it
Does UV Light Kill Fleas?
UV light does attract fleas, but does it kill them? The answer is yes, but it takes a very long time. UV light has radiation, something that affects cells of all living things.
With continued exposure, it can start to manipulate and mutate cells, killing them or turning them into cancer-causing cells.
While that sounds like something that could kill pretty fast, this entire process happens over a long period of time, something that you don’t want with bugs.
Plus, fleas can feel the effects of UV lights and will start to move away and out when they feel it taking effect. Instead of using UV light to kill fleas, you should consider:
- A powerful vacuum
- A steam cleaner with really hot steam
- A washing machine with lots of bleach
- Chemicals that will wipe out fleas and other tiny insects.
Do Fleas Like Light or Darkness?
Due to fleas’ genetic makeup, they cannot see red light. What they can see however is yellow light, something that they are mostly attracted to. Fleas do like yellow light but they also light darkness, so long as it’s quick.
When exposed to light and switching lights off quickly, these little jumping insects think it’s a shadow and await their next feast.
When observing fleas in different lighting conditions, researchers found that fleas will move around from place to place depending on the circumstances.
They do like to be exposed to light and will gravitate toward it if they are in a dark place. However, not just any light will do, with many fleas very sensitive to sunlight.
Due to their affinity for light, you could set up a small contraption to get rid of them quickly using just a light bulb and a small shallow pan of water.
To execute, simply:
- Turn on the light bulb
- Fill the pan with water
- String the light bulb above the water
- The fleas will jump in the water to get to the light and eventually drown.
Knowing if fleas are attracted to light can help you get rid of them, avoiding getting bitten, and sleeping soundly wherever you may roam. Shine some light and see where they are to protect your space.
