Bed Bug Detection Kit The ability to detect bed bugs during the early stages of infestation when only a few bugs are present is really important, but to date the early detection tools and methods are very limited. Mattress and box spring encasements are the first available early detection tools. Now we look at a number of detection tools and methods including the detection of the scent of dogs, CO2 monitors and passive interception devices that make early detection of bed bugs a reality. It is important to note that although monitoring tools and methods have improved; There is no really reliable tool or method for detecting bed bugs. For this reason, regardless of which method or device is implemented, the failure to identify bugs can not be used as an indicator that no bugs are present and it is always recommended that a combination of methods be used to increase the likelihood of finding low activity.
The following is an overview of current monitoring methods and tools:
Visual inspection is time-consuming, labor-intensive and perhaps the most unreliable of all inspection methods when it should detect low-level infestations where only a few bugs are present. The reason why visual inspection is so unreliable is based on the hidden and vague nature of sleeping insects and their tendency to hide in very narrow gaps too thin to see or areas not visually accessible like inside the couch, under sideboards, or under floor boards Regardless of these limitations, visual inspection is still the most common method, as it can be done by anyone who knows what to look for and does not require the purchase of a special device. All it takes is a good flashlight and maybe a magnifying lens to help see the little eggs and nymphs. (See the section on Biology and Behavior and Early Detection)
Discussions for mattresses and spring boxes are the first available early detection methods available. In addition to protecting mattresses and box springs from becoming full, the wrappers have helped to expose many bed bug infestations by removing many hiding places in mattresses and spring boxes and forcing insects to sleep out into the open on the smooth outer layer where they can be easily seen and handled. There are many branded encasements and not all are created equal, nor is it effective to use as a bug detection tool and / or a bed management tool. For more information on affixing see the Mattress and Box Spring Encasements section.
Canine Scent Detection:
The detection of fish scents has become an increasingly popular screening method for detecting low-grade infestations. The biggest problem is that there is a big difference in the quality and effectiveness of the dogs’ aroma detection services available in certain areas. A well-run dog scent program can produce highly effective results and will often reveal infestations that may be missed during visual inspection. Unfortunately, the poorly run program prevalence is a real threat that can lead to discrediting this valuable inspection method. There are two main issues related to the dog’s scent inspection program. The first is the concern that dogs may fail to detect existing sleeping bugs and the second is the opposite, where dogs mistakenly suggest bed bugs. Most canine aroma detection companies advertise an accuracy rate of 95% or more. This high degree of accuracy has been demonstrated under controlled conditions in the University of Florida study. However, a much lower accuracy rate was observed in a study conducted by Rutgers University under real-world conditions using a naturally-filled apartment. IWhile is difficult to overcome the failure of dogs to detect infestations, false alert issues can be addressed by requesting some kind of verification system available to ensure that bed bugs follow a positive indication of the dog. One way is to produce evidence of infestation (see the section on How do I find out if I have bed bugs, or early detection for more information about verifying the presence of bed bugs), the other is to institutionalize a double blind verification system see the section on Canine Scent Detection for a full discussion on this topic.
Passive interception device:
Passive interception devices are really simple, cheap trap traps that can be put under the foot of the bed frame and the upholstered furniture. Once installed, they intercept and catch the bed bugs as they travel to the sleeping area and rest. Interception devices can also catch sleeping bugs as they migrate from beds and furniture, preventing it from attacking other parts of the structure and into personal items that are difficult to treat.
The concept behind how the interception device works is to let the bed bug climb up the outside of the textured device but then fall into a well that has a smooth, smooth side that can not be climbed so that it gets stuck in the well. Once the interceptors are placed under the feet of the furniture, they work 24/7 with very little care needed, other than occasionally emptying trapped insects and cleaning the well periodically or cleaning and tearing down the well wall with cotton balls dipped in powder (depending on the device you are using).
The term passive monitor is used to describe this type of trap because no feed or attractant is used such as CO2, heat or other attractants to pull bed bugs into the device. But in fact, the interception tool is nothing but passive. By placing them under the foot of the bed, the person sleeping on the bed serves as an attractant, and there is no better appeal than the source of the bug food. Indeed, field research has shown that interceptors, who are left at the foot of the bed for one week, are more effective at detecting low-grade infestations than active CO2 monitoring devices.
It is important to pull the bed away from the wall and not allow linens, blankets, dust ruffles or other items to hang on the bed in contact with the floor, so that insects have no alternative path to the bed, thus forcing them into interceptors
University research has shown that passive intecrpetion devices are one of the most effective tools available to detect bed bugs and also play a role in reducing the number of bed bugs during management efforts, and therefore also a sleep-bug management tool. The use of interception devices can also be extended to areas far from bed and rest areas because bed bugs tend to travel in full residences and prove to be much more mobile than previously believed. For this reason, interception devices placed in the corner of the room and in the closet can also help detect low-grade infestations, evaluate the effort of managing bed bugs and provide insight into areas where sleep-bug activity exists.
Commercially Marketable Active Monitoring Devices:
Monitoring devices using carbon dioxide use have been developed to detect bed bugs. In addition to using CO2 as the main drawer, some of these devices also use other attractants such as hot and chemical baits. At present only one commercially available CO2 trap is available, Verifi Bed Bug Detector by FMC. In addition to Verifi, NightWatch® Bed Bug Trap (produced by Biosensory) may be available again in the future but problems with registration of this device caused it to be removed from the market. Both are similar in concept, using CO2, heat and the lure of chemistry to attract bed bugs, but there are also some significant differences.
The effectiveness of the Verifi detector is still being evaluated but research shows that it has the ability to activate bed bugs within a distance of 5 feet from where the device is located. Therefore, while the best protocol for using this monitor is still being evaluated, an imaginary 5-foot radius around where the monitor is mounted should be used to help determine the coverage area of the monitoring program. In addition, preliminary field testing has shown that Verifi has the ability to detect a high percentage of low-level infestations and is likely to be an important detector in a sleep-forward bug monitoring program.
As mentioned for passive monitors, active monitors can also be used in areas far from bed and rest areas to monitor the activity of bed bugs but because of the cost of active monitors, it is not economically economical as passive interceptors that usually cost far more a little. per device
Do It Yourself (DIY) Monitor:
A simple but very effective monitoring tool can be built using pet food bowls, masking tape, insulated containers and dry ice. The design of the trap comes from research conducted by entomologist Rutgers University, Dr. Changlu Wang. The design of this trap is very effective and is shown to catch sleeping bugs at low level infestations in a field study conducted in an apartment.
While the concept is simple, if the right animal food bowl is not utilized the trap will not be effective. In addition there are potential dangers associated with handling dry ice that must be considered. These hazards include but are not limited to shortness of breath if too much dry ice is used for the volume of the monitored area and burns that can easily be produced if dry ice is in contact with the skin. People using this monitoring technique should familiarize themselves with safe handling of dry ice and perform proper maintenance when operating the monitor. Due to this problem, we recommend that pest management professionals not use homemade monitoring devices at client sites but purchase commercially available devices that have been manufactured to monitor / detect bed bugs. In addition, we want to make sure that anyone who chooses to use this method realizes that this is just a monitoring and detection tool, and not a controller and also not a solution to bed bugs.
As stated earlier, it is important to note that although monitoring tools and methods have improved; There is no really reliable tool or method for detecting bed bugs. For this reason, regardless of which method or device is applied, the failure to identify the bug can not be used as an indicator that no bugs are present. Low-level infestations can still pass detection regardless of detection methods implemented. In addition, the detection tool does not become confused as a solution to the problem of bed bugs, its main function is to detect bed bugs.
