Mosquitoes carry certain diseases affecting humans, including the West Nile Virus. These insects often appear around areas with standing water, a high rainfall or humidity. When adding a propane fire pit to your yard, you risk the mosquitoes attacking you, your family and guests. Certain types of mosquito repellents are suitable for use around fire pits.
Chemical repellents deter mosquitoes by blocking certain environmental cues attracting them, such as water vapor. Colorado State University recommends deet repellents applied directly to the skin. Some mosquito repellents contain plant-derived chemicals. The repellents work for several hours and keep mosquitoes from biting. When using the repellents outside, stand away from the fire pit and remain away from the area until the product dries on your skin. Certain chemicals are flammable and should not be used around any type of flames.
Ultraviolet devices kill mosquitoes. If you have an electric outlet or electric source near your propane fire pit, hang a bug zapper or a similar device. The ultraviolet light attracts the mosquitoes, luring the insects away from your family and guests. The mosquitoes fly into the light and die upon impact. Some brands add CO2, which further attracts the insects.
Citronella repellents come as candles and wristbands. The products work by emitting a scent that repels the bugs in your yard. Candles mix citronella oil into the wax, which slowly releases the scent around the yard as the candle burns. The wristbands attach directly to your arm. According to the University of Florida, a product containing 10 percent citronella was only effective at keeping mosquitoes away for 20 minutes. As the amount of citronella dropped, so did the effectiveness.
The University of Florida warns against using natural remedies for repelling mosquitoes, including onions, vitamin B, bananas or garlic. The University states that no scientific evidence supports the claims that natural remedies work. The school also warns against the use of sound emitting devices for repelling mosquitoes, as no studies or research supports the manufacturers' claims.
