A home remedy for reducing the number of mosquitoes on your property is to set up buckets as traps. Fill the buckets with water then throw in a bunch of plant material such as leaves, grass clippings, spent flowers, whatever, because you want the water to get all cruddy (stagnant). This will cause it to attract female mosquitoes to lay their eggs. Attracted to the water, they lay eggs but the nymphs won't survive to become adults, because you will have added a mosquito dunk or the Bti granules to the water.

Bti is Bacillus thuringiensis 'Israelensis' and it's sold as mosquito dunks and mosquito bits. The Summit brand will probably be the easiest to find. Buckets tucked away in gardens, near the house, can help reduce the number that are around your most traveled areas and in the house. Use Mosquito dunks or granules in other water as well, such as the trays beneath pots, bird baths, fountains, and such.
