When experimenting with bed bugs in an experimental arena it is sometimes important to discern where the bugs go first. When using climb up interceptors the repellency inherent in the device will mask any information on where bugs go first. As such I highly recommend the experimenters use modified glue boards as they have far less repellency offering a clearer picture of bed bug behaviour. I strongly suspect the modified glue board will become a staple in competent bed bug labs as an excellent experimental tool.
