As I recall, one of the major carriers of Dengue is the Asian tiger mosquito,
which is notorious for using small water sources for breeding. However, the
only known mosquito associates of Neps and Sarrs. are several harmless
mosquitoes that are of no risk to humans. Someone can correct me if newer info
is available.
As far as the tiger mosquitio goes, I would be surpirsed if it is a problem in
the UK because it is a tropical species. (It is becoming a problem here in
Florida, although no cases of Dengue have been found here.)
As for larvicides, I do not put anything in my traps, there are just way to
many other water sources available for ambitious skeeters'. I am currently
trying one of the donut style larvicides in some of my trays and they seem to
be working.
