As far as detector lights for bed bugs are concerned, there aren’t that many great products on the market. However, if the Top 3 aren’t to your liking, here are a couple of other products that might strike your fancy.

This Vansky 12 LED Black Light offers a comfortable portable design, making it easy to take on the road. It is, however, smaller and weaker than other similar products so if you’re looking for something to use at home, we’d recommend the products in our Top 3.

A combination of a UV flashlight and a regular tactical flashlight, this Morpilot 2 in 1 UV Flashlight is both versatile and sturdy, thanks to its aviation grade aluminum frame. It is intended for traveling, however, and there are more effective and practical choices for residential or commercial use.


UV LED flashlights aren’t a complex product group to examine. Almost regardless of their individual specifics, they all use LEDs to emit ultraviolet light which helps with detecting a lot of things that we typically can’t notice on regular sunlight. The intended purpose of most UV LED flashlights is to help detect pet urine or other bodily fluid stains so that’s often how they are marketed. A lot of customers also use them to find scorpions in their yards’ grass as the UV light makes these bugs glow quite visibly.

Detecting counterfeit currency or documents is another good use for UV LED flashlights but so is detecting bed bugs. UV light works on bed bugs in the very same way that it does on scorpions. It’s also useful in detecting the miniature blood spots left after crushed bed bugs. Because bed bugs are so small, however, simply shining a light on your bed or couch is often not enough to notice them. Instead, try using something like a credit card to press against the fabric and make the little pests pop on the surface.


The key thing to finding success when dealing with bed bugs is having the right tools at your disposal. If the UV light you’re using is not up to par it can cause you to skip over a lot of bed bugs and be ineffective in dealing with them. That’s why it’s important to buy high-quality products as a cheap but poor UV light will be just a waste of money. They things to look for in a UV LED light are:

  • The light is bright enough.
  • The LEDs are of a high enough quality to last for years.
  • The light’s width is adjustable.
  • The design is comfortable enough to use both at home and on the road.
  • The UV light will also be useful for other things you might need it for in the future such as locating urine stains, scorpions in your yard, and so on.

Finding a product that checks all these boxes can be time-consuming and require reading a lot of consumer reviews but it will be worth it. UV LED flashlights may not be the most expensive purchases but finding and using a good one can save you a lot of time and troubles in dealing with a bed bug infestation. If you are at a loss for where to start we recommend keeping these brands in mind at first: Moriplot, Vansky, Arf Pet, INFRAY and TaoTronics.


UV LED bed bug detector lights are useful both to inspect whether there are bed bugs at all, as well as to locate individual bugs as you’re trying to get rid of them. A common manual way to get rid of bed bugs is to find them all out individually using UV light and a pressing tool (such as a credit card) and then capturing them on a sticky surface (such as duct tape). This can be a time-consuming method if you have too large of an infestation on your hands but even in those cases, a good UV LED light can be useful at pointing you in the right direction. The key thing to remember when dealing with bed bugs (or any other insect pest really) is that you need to be thorough and not leave any living pest behind. To that end, detection tools such as a good UV LED light can be priceless.


As you can see, bed bug detector lights have their benefits as well as limitations. They certainly aren’t the end all be all of bed bug prevention but when used properly they can help you both detect and deal with these annoying pests. Of course not all bed bug detector lights are created equal and here are our Top 3 suggestion again:

  • The TaoTronics FL002 sports 51 LED black lights and comes with UV sunglasses. It also includes batteries and is a very effective and long-lasting method of detecting bed bugs, scorpions, pet urine or other bodily fluids. It’s more on the expensive side of the market but if you need a good UV LED flashlight this is one to consider.
  • The Arf Pet UV Light is another good option with its 100 LEDs and a widespread. It’s also not a cheap product but it’s very effective at inspecting large areas quickly and easily.
  • The INFRAY SD-002UV is our third suggestion because of its great design. A pocket option for those that travel frequently, the Infray offers an easy way to inspect your hotel rooms, cinema or bus seats, and other such locations where bed bugs typically dwell before they crawl onto our clothes or luggage.
