around ponds
If by "around ponds" you mean in the grass, bushes, etc that surround your pond. Moving water and fish in your pond will keep your pond free of larvae, but if you're like us, the mosquitoes still have plenty of places to hatch and controlling them around the pond without getting chemicals IN the pond is a challenge.
We burn citronella lanterns, plant things they don't like (mint, lavender, lemon balm, lemon thyme, etc) and then just avoid being outside when they are bad. We live in an area that has so many natural bodies of water that there is very little we can do to control them, except by not adding to the problem in our own yard. We use no chemicals of any kind in our yard and that includes for insect control. Sometimes we just gotta let them have their space, too.
I do use mosquito spray on myself if I have to be outdoors during the "witching hour" and then just make sure I shower and wash it off right away when I get back indoors. West Nile is a real problem in our area, so it's a two-edged sword.
