Apparently there are some types of plants (like lavender, mint, rosemary or catnip) which mosquitoes don't like being around for whichever reason. Having some near the micropond could be a pretty elegant fix if it works.
The fact that all of these plants have delightful smells confirms my dislike of mosquitoes - not only do they bite and spread disease, they also have bad taste in garden plants.
Sweet Flag (Acorus calamus) is a similar aromatic grasslike plant that grows aggressively in ponds. I planted a few thin stalks a couple years ago and now it has outgrown five planters and the rhizomes are 2 inches thick. One other advantage of this plant is that the stalks provide a molting place for dragonflies.
