The answer to 'why do I have fumigation' is that fumigation is typically required when a home has a severe pest infestation, such as termites, bedbugs, or rodents. Fumigation involves sealing the entire home and treating it with a toxic gas to eliminate the pests throughout the structure. This is a drastic measure that is only necessary in extreme cases when other pest control methods have failed.
Fumigation is a complex and dangerous process that should only be performed by licensed and certified professional pest control companies. It requires the home to be vacated for several days while the gas is applied and dissipates. Improper fumigation can lead to serious health risks, so it's crucial to hire an experienced pest control expert to handle it safely and effectively.
