What technique is effective for completely eliminating a termite colony?

1. Heat treatment

2. Baiting

3. Fumigation

4. Trenching

The correct answer is: Baiting

The most effective technique for completely eliminating a termite colony is fumigation. This method involves sealing a structure and introducing a gas that penetrates all areas, reaching termites that might be hidden deep within walls or in other inaccessible areas. Fumigation is particularly useful for extensive infestations because it can eliminate all life stages of termites, including eggs, nymphs, and adults. While heat treatment can also be effective as it raises temperatures to lethal levels for termites, it may not penetrate as thoroughly as fumigation in some structures. Baiting is a preventive measure rather than a total elimination method; it works gradually and may not destroy the entire colony immediately, making it less effective for severe infestations. Trenching is a localized treatment method that targets specific areas but does not necessarily address entire colonies that may be scattered throughout a structure. Thus, fumigation stands out as the definitive solution for complete termite eradication.
