Explanation:

Fumigation

  • Fumigation is a chemical method of termite control.
  • It involves the use of toxic gases or chemicals, such as sulfuryl fluoride (commonly known as Vikane), to eliminate termite infestations.
  • Fumigation is not a non-chemical method and instead relies on the application of chemicals to kill termites within a structure.

 Additional InformationBaiting

  • Baiting is a method of termite control that involves placing bait stations in the ground around a structure.
  • These bait stations contain materials that are attractive to termites and may include substances that inhibit termite growth or kill them.
  • When termites feed on the bait, they carry it back to their colony, effectively reducing the termite population over time.
  • Baiting is a non-chemical method because it typically doesn't involve the use of toxic chemicals or pesticides.

Trapping

  • Trapping is another non-chemical method of termite control.
  • Termite traps are devices placed in the ground to intercept and capture termites as they forage for food.
  • Traps are designed to physically block the termites' path and capture them when they come into contact with the trap.
  • This method does not rely on chemical treatments to control termites.

Heat treatment

  • Heat treatment, also known as thermal remediation, is a non-chemical method of termite control that involves raising the temperature of the infested area to lethal levels for termites.
  • This process typically requires specialized equipment that heats the affected area to a temperature that kills termites without using chemical pesticides.
