Mosquito repellent plants are basically just nice warm fuzzy thoughts. For your slow moving creek, the best thing to do is to speed it up. Go out there with a shovel and wherever it's puddling, trench it to move along. If a rock is in the way, move it, just get the water moving. You would be surprized at how easy it is to dry it up some. If the woods are thick in wet leaves try to blow them around to higher ground. If your gutters are full, that's one of the best breeding grounds for them.
A good back pack sprayer with Cross Check (SiteOne Landscape) insecticide is your best bet to reduce the population. After mowing the grass, walk and spray all parts of your property. especially in, around, and under the shrubs. Spray those woods and the creek area. Use the adjustable tip on the sprayer and try to get the spray into the gutters (tip: don't let the spray fall back down into your face).
Try this and do it weekly and let me know how it works in a month. This is better than what many of the mosquito companies do IF you spray it liberally.
Also, Purple Martins can eat their weight in food a couple times a day too so get you some martin houses.
