One of the most popular ways of temporarily (or for one-time use) defending a
wooden construction from termites.
In the first case, the holes are drilled and the insecticide is poured inside to prevent
further infestations and completely stop termites from appearing.
In the seconds case, you drill holes into or close to the nests, apply an active
insecticide and that way you get rid of the nest immediately. Both are very effective
ways of SPECIALIST pest-control used world wide.
