Check the plants twice a week. If you see the oily black egg rafts,
remove them or add a small piece of the dunk you purchased.
Mosquitoes prefer dirty stagnant water to lay their eggs. If the
bromeliad is large enough you could add a small fish to the water.
Soap does reduce water tension but soap is definately not good for
watering plants. Mosquitoes will lay eggs in gutters, old tires,
watering cans, pot saucers, bird baths, moist soil, etc. I have a
7,000 gallon pond with fish that actually reduces the mosquito
population.

I have purchased dunks, but using them for bromeliads isn't very
convenient, and I think it might not be effective, either.

I saw a product that claims to reduce the surface tension of water so
that mosquitos can't land on the surface to lay their eggs, but I
think it would be too expensive to use for watering the bromeliads
regularly. It claims to be made of (unnamed) ordinary household
products. Does soap reduce surface tension? Maybe I could add small
amounts of soap or detergent to the water? Any ideas, anyone?
