The only way I am aware of to get rid of mosquitoes inside is to eliminate water sources where they can breed. Look around your house for standing water, such as that found in overwatered house plants. Frequently water sits in saucers, providing a breeding ground for pests, and it's not great for your plants either! I always had a vase designated for rooting plant cuttings in the house. One day I checked the water and it was positively seething with larvae! Give your home the once over and of course, keep doors and windows without screens closed.
