Determining the right frequency for fumigation depends on your home's risk profile:
Many pest control services recommend quarterly treatments (every 3 months) to maintain effective protection.
In some cases, fumigation effects can last up to four years, though termite inspections every 2–4 years are wise.
Once infestations are resolved, routine re-fumigation may not be necessary; annual inspections are often sufficient.
Consult a trusted pest control professional to develop a tailored inspection and treatment plan specific to your property.
