It is an advantage to be able to detect an infestation early on so that you have time to take action before it spreads. The surroundings, facilities and raw materials should be examined regularly. The purpose of an inspection may also be to see the extent of an infestation or maybe just to monitor the effects of a completed control.
Reasonable and adequate inspection equipment includes: Flashlight, notebook and pen, plastic bags, a felt pen and a small handful of slides or containers with lids and labels. To collect the animals use tweezers, a spoon, a fine brush and a roll of transparent tape to trap the very small insects. In addition, it is an option to bring an aerosol with pyrethrin to draw insects out from their hiding places, and maybe also a lamp with ultraviolet light, to detect rodent hair and urine. With an infrared remote thermometer you can get an idea of where in a room, the temperature is favourable for insects or even detect heat due to many living insects. With a pocket mirror it is possible to see behind and under things and with fibre optics connected to a camera (a so-called endoscope) it is possible to see into cavities that we cannot otherwise get to. Finally, a digital camera is a nice addition.
Primarily to document the observation of pests or their tracks, and secondarily to illustrate conditions which can then be discussed with others.
