Bed Bug Repellency Test
Bed Bug Repellency Test
Bed bug repellency test is designed to check whether a given repellent product can protect humans from bug biting as well as deter the bed bug infestations in personal belongings to provide a bug-free environment.
Bed bug repellency test aims to determine the efficacy and action of repellent products against certain bed bug strains. Bed bug repellent evaluation plays a critical role in implementation of robust pest control management practices. Efficacy testing helps manufacturers to understand the performance of products for their intended use and develop safe and effective repellent products.
Bed Bug Repellent Test Requirement
- Test organisms: One field-collected strain of the common bed bug, Cimex lectularius is used for the test.
- Bed bugs rearing: Field collected bed bug strains are reared (breeding and maintaining populations of bed bugs) in the controlled laboratory settings.
- Sample size : The product samples should be in sufficient quantity to effectively evaluate the efficacy of the test sample and achieve the required accuracy and precision in results.
- Replicates: The experiment is designed with five replicates of 10 bugs, and with an equal number of replicates for treated and control replicates is used for the study.
Bed Bug Repellency Testing Method
Non choice and choice tests are conducted to determine if pesticide product repels bed bugs.
- No – choice test
Volatile repellents – This test runs with 5 replicates using ten bed bugs each time with an equal number of treated samples and untreated controls. Bed bugs are exposed to the repellent vapors (sample product) to check if the repellent can keep the bed bugs away from the system mimicking the human host(e.g. carbon dioxide and heat).
Impregnated fabric – This test is performed on both treated and untreated pieces of fabric using a test system to mimic the human host (e.g. carbon dioxide and heat). The test determines if a bed bug is repelled by the impregnated fabric (bed bug repellent) or not.
- Choice test
Volatile repellents – A modified version of the still-air olfactometer can be used to evaluate the efficacy of bed bug repellent products. The still-air olfactometer device must have a source of carbon dioxide and heat to mimic a human host. The test involves looking at the mobility behavior of the bed bugs in the presence and absence of repellent in the treated area when there is a human mimicking host. A negative control is also set up with carbon dioxide and heat (mimicking human host) without repellent.
Alternatively, Y-tube assay can also be used to check the bed bug’s response to different scents and repellents.
Impregnated fabric – Both untreated and treated fabric are tested together with bed bugs placed onto the top of fabric. Their response/ movement either towards or away from the treated fabric is observed and measured.
In parallel, a control test is also run with an untreated fabric.
Importance of Bed Bug Repellency Test
Repellent products come under significant pest control strategies in managing bed bug infestations and safeguarding human living space. Using effective repellents can reduce the burden of bed bugs and their annoyances. Laboratory bed bug repellency assessment describes the test method to assess protection time and repellent action of test products against bed bug strains. These assessment methods follow standardized procedures to ensure efficacy of tested products for their intended application.
