The answer to 'signs of fumigation' is that the most common signs of fumigation are a strong chemical odor, visible white or yellow gas, and the presence of tarpaulin or plastic sheeting covering the home or building. Fumigation is a pest control method that uses highly toxic gases to eliminate infestations of termites, bedbugs, or other pests.
Homeowners should be aware that fumigation is a complex and dangerous process that requires professional intervention. DIY fumigation is not recommended, as it can be extremely hazardous if not done correctly. Attempting to fumigate your own home could result in severe injury or even death. If you suspect a pest problem that may require fumigation, it's best to contact a licensed and experienced pest control company to assess the situation and determine the appropriate course of action.
