The answer to 'why do I have fumigation' is that fumigation is a pest control method used to eliminate severe infestations of insects, rodents, or other pests. Common causes that may require fumigation include heavy infestations of termites, bedbugs, or other difficult-to-control pests. Symptoms may include visible signs of the pests, structural damage, or health issues related to the infestation.
Fumigation is a complex process that should only be performed by licensed, professional pest control technicians. It involves sealing off a structure and releasing a toxic gas that penetrates all areas to kill pests. This is not a DIY solution, as improper handling of fumigants can be extremely dangerous. If you suspect a pest problem that may require fumigation, it's best to contact a professional pest control company to evaluate the situation and determine the appropriate treatment.
