Some termite control operators here have had success using entomogenous
nematodes, however, I have no data on tropical termites. I recommend
talking it over with a supplier, as the nematodes are fairly host
specific, and identifying the proper nematode strain is essential. The
nematodes are obligate parasites, and as such, appear to be independent
of any constraints associated with compost or chemicals.
Repeated applications of carbofuran can build up an aggressive soil
microflora. In our studies, carbofuran applied the first year had a
half-life in soil of something like 57 days, but that dropped to less
than three days by the third application. While this means that the
carbofuran is much less toxic to nontarget organisms under such
situations, it also means that the carbofuran is much less toxic to
target organisms.
