Hi, my cepts had bugs problem.

I discover that my cepts is infected by unknwon bugs. The little bugs are very small (around 1mmx0.2mm), no wings, brown to black colour, always concentrates on the surface of new growing pitcher, the surface of new growing pitcher then apppears some tiny brown dots.

I recalls that during end of week of October, a mother bugs fly on to the moss and suspected to produce eggs
the mother bugs are black colour with two colourless wings, with size 1mm x2mm.

May anyone know what is the name of this kind of bugs, and can I use any type of drugs to kill / prevent from this bugwithout have any harmful effect to cepts ? Thank you !!
