What are the disadvantages of fumigation?

Fumigation can pose several disadvantages, including potential health risks to humans and pets due to exposure to toxic gases used in the process. Additionally, it may require occupants to vacate the premises for an extended period, leading to inconvenience and potential loss of income for businesses. Environmental concerns also arise, as some fumigants can contribute to pollution and harm non-target organisms. Lastly, improper application can lead to incomplete pest control, requiring repeated treatments and further costs.
