Bed Bug Supply Review - see what our experts have to say about this product
In order to confirm the presence of bed bugs in a room, especially in unoccupied rooms such as family rooms or recently vacated bedrooms, homeowners, property managers, and pest control professionals often employ the use of active bed bug monitors. These devices feature a luring system that imitates a sleeping person, drawing bed bugs out of their hiding places and into a trap that the operator can check regularly.
The NightWatch has been on the market for years. It was developed as the first professional-grade bed bug monitor, and is still the best tool for the job today. The secret to its success is that it uses three different luring methods: carbon dioxide, radiated heat, and a kairomone scented lure. This combination is the best way to mimic a sleeping host, which is the key to drawing bed bugs out of their hiding places throughout a room so that an operator can confirm their presence.
The NightWatch comes in a few basic pieces, and setting it up for use is pretty simple. The packaged unit comes with a power cord, two pitfall traps (one for each side of the monitor), a four-pack of kairomone lures, and a top cover that conceals the kairomone lure and part of the radiator. Everything you need is included except for a Co2 bottle, which can be ordered separately on our site and filled for a few bucks at most local paintball supply or sporting goods stores. Any bottle around 18 to 24 ounces in capacity should fit as long as it has a brass fitting.
Once set up, the NightWatch will automatically release its lures from 10 PM to 6 AM for 3-4 nights. We recommend running the unit for at least 14 days to ensure not bed bugs are present. As bed bugs come out of hiding to look for the source of the attractants, they'll climb up the grippy ramps on each side of the NightWatch and fall into the pitfall traps at the top. These pitfalls make it easy to confirm bed bug activity in a room, or to monitor changes in the area's bed bug population.
Without an active bed bug monitor, and without a human host to act as the bait, it's difficult to determine if there are bed bugs in a room. A bed bug will only feed once every five to ten days when a host is available. If they can't find one nearby, they may enter a hibernative state and remain dormant for up to a year.
The NightWatch active bed bug monitor is the most effective way to solve this problem. It can be used to confirm bed bug activity in unoccupied rooms, such as recently vacated bedrooms, hotel rooms, or apartment units. The NightWatch also essential when treating these unoccupied spaces, since it can draw bed bugs out of hiding to make sure that they come in contact with any chemical sprays or powders that have been applied. Whether you need an active monitor for confirmation, prevention, or treatment, there is no better choice on the market than a NightWatch.
Product Information
NightWatch is an innovative product for pest control operators used to detect bed bug infestations at the earliest stages. BioSensory developed the NightWatch Bedbug Monitor based on knowledge of a bedbug's physiology and an understanding of how the pest seeks a blood meal.
Because bed bugs normally bite once every 3 to 4 days, a new infestation of just a few bed bugs often goes unnoticed. It's important to run the machine for at least 14 days to ensure the room has been monitored properly. Bed bugs are often undetectable by the person being bitten and by the most expert professionals in the field. At first, the person thinks the bite is a pimple and then a rash. By the time a skin reaction is recognized as an insect bite, the infestation has grown to hundreds of bedbugs and eggs and is expensive to eliminate.
The NightWatch active monitor can detect a bed bug infestation even in its earliest stages, allowing for a faster treatment response. This saves time and money that would otherwise be spent inspecting for bed bugs before starting treatment.


The NightWatch is the only monitor on the market that combines three different lure methods:
Carbon Dioxide: CO2 has been proven again and again, both through lab studies and professional field usage, to be the most effective way to attract bed bugs. We emit this gas while we breathe, and bed bugs are highly sensitive to it. The NightWatch slowly emits carbon dioxide at a similar rate as a sleeping person.
Kairomones: In addition to carbon dioxide, an odor attractant is added that mimics the subtle chemical scents of a sleeping person. This host odor attractant works for 7 days, and has been shown to be incredibly effective at luring bed bugs into the NightWatch's pitfall traps.
Heat: The missing element in many competing lures is heat. The NightWatch uses a thermal plate that radiates heat to imitate a warm body. When combined with carbon emissions and kairomone odors, bed bugs are easily convinced that there is a sleeping host nearby.

Insert the filled Co2 bottle into the opening opposite of the LED display and screw it into the outlet inside. Remove the label covering the opening of the kairomone lure and place the lure on top of the radiator.

Attach the pitfall traps to each side of the radiator by sliding the back of the traps down onto the vertical ramps. Attach the top cover and plug the power cord into the jack below the LED display.

Hold down the "TIME SET" button to set the current hour, then press the "TIME SET" button repeatedly to set the current minute. When the time is set correctly, the NightWatch will only emit CO2 and heat from 10 PM to 6 AM.
There are two types of bed bug monitors on the market: passive monitors and active monitors. Passive monitors, such as ClimbUp Interceptors, can trap bed bugs that cross them for monitoring or defensive purposes. However, passive monitors do not have their own luring system; they usually rely on a sleeping person to be in the room acting as a bait.
Active monitors, such as the NightWatch, use their own lures to draw bed bugs out of hiding and into their traps. This makes the NightWatch indispensable for confirming bed bug activity unoccupied rooms, such as family rooms or recently vacated bedrooms. The NightWatch is essential when treating these unoccupied spaces as well, since it can draw bed bugs out of hiding to make sure that they come in contact with any chemical sprays or powders that have been applied. Without using the NightWatch in rooms without a host, bed bugs may just remain dormant without an incentive to become mobile and cross over the applied chemicals.
