Identifying Noises Caused by Wildlife in Structures
WARNING: Noises, sounds (in wildlife damage settings) are not a very accurate way to determine the species causing a problem. Like pain, noises only tell you that something is wrong; rarely what is wrong. The reasons for this lack of accuracy is that people have different hearing abilities, and activity schedules. You also have to take into account insulation thickness and the kinds of materials used in the building's construction. Finally, remember you can't hear a noise if you aren't in the right part of the building at the right time. Please read this information with the appropriate skepticism.
NOTE: Before inspecting any of these locations, learn
proper inspection and saftey techniques
