Odors can be a nuisance, and sometimes dangerous. It is important to be able to identify and locate the source of an odor in order to remove it. ### How to Locate the Source of a Smell There are a few things you can do to locate the source of a smell: * **Follow your nose.** This may seem obvious, but it is the most effective way to find the source of a smell. Start by standing in the area where the smell is strongest and then follow your nose until you find the source. * **Use a fan.** A fan can help to circulate the air and make it easier to find the source of a smell. Place a fan in the area where the smell is strongest and then turn it on. The smell will be drawn towards the fan, making it easier to find. * **Use a smoke pen.** A smoke pen is a device that produces a harmless smoke that can be used to find the source of a smell. To use a smoke pen, simply hold the pen near the area where the smell is strongest and then release the smoke. The smoke will follow the path of the smell, making it easier to find the source. Once you have found the source of the smell, you can take steps to remove it. In some cases, you may be able to remove the smell yourself. However, in other cases, you may need to call a professional odor removal service.
