There are many ways to get rid of mosquitoes (and prevent mosquito bites) in your Orlando lawn:  Eliminate breeding sites Anything that holds water must go. Drill holes in tire swings, get rid of plant saucers, and store buckets and kiddie pools in a shed when not in use. Use a larvicide Bti, or Bacillus thuringiensis subspecies israelensis, is a convenient, safe way to kill larvae in containers that you can’t empty, such as water-holding plants (like bromeliads) or open rain barrels. Use an adulticide This is a last resort option. Killing adult mosquitoes also means killing beneficial insects, including honey bees and butterflies. Use the preventive options listed above first, then consider organic adulticides, and only use chemical insecticides as a last resort. If you decide to spray for adults, avoid the flowers and don’t spray during the daytime hours, when bees are most active.
