I'm not totally sure of this, but I don't think mosquitoes will be able to breed unless there is a puddle of standing water (or a layer of stagnant water). BUT, I try not to let the surface remain too wet, just in case.

I've wondered if pitchers would be possible breeding grounds, but they fill up so fast with caught insects, I haven't worried too much.

I have a carnivorous plant bog and haven't had any real pests so far. A very few slugs, easily caught. Spiders and ants (those surprised me) seem to enjoy the bog too, despite the wetness (and despite being eaten in the ants case). But they are hardly pests.

What kind of bog (types of plants) are you planning on?
Have fun with it!

Mozzies can only breed in standing water. If you intend visible standing water, go to home depot and buy 'mosquito dunks'. Break off pieces and use in the standing water. It works.

Or get some mosquito fish. They work too.

Carnivorous plants don't require standing surface water, so you won't have a place where mosquitos can breed.

I have a standing water bog.
I use the mosquito dunk stuff but I buy it
in a granular form so it is easy to broadcast
into every nook and cranny.

We have a small pond with a stream at one end, water is always moving, we have mosquito fish and NO mosquitos!

PS county can give you mosquito fish

I forgot to say, I have 2 other bog areas, with NO mosquitos. You don't need standing water in a bog.
