The scent of the citronella oil in the tea light candles when heated releases the odors into the air and acts as a smoke screen to disguise the human scent as a host to the insects. In order for the citronella tea light candles to be an effective insect repellent for an outside event, the tea light candles must be burned in and around the perimeter of the area you what to be insect free. It is also important to light the citronella tea light candles and keep them burning during the entire event.
The best part of the effect of citronella tea light candles is that the benefit is twofold. Plus, you can always help prevent bites with mosquito repellant. Outdoors, the best solution for combatting these pests is to eliminate the source of all mosquito life: standing water. Getting rid of mosquitoes is not unlike getting rid of mold or the common cold: These things are facts of life—they're everywhere, and you can't possibly get rid of them or prevent them entirely.
What you can do is take steps to minimize their numbers. Like mold, mosquitoes need moisture to grow and thrive, so most treatment steps focus on eliminating or treating potential breeding grounds of water. You can also use fans to keep mosquitoes away when you're sitting outdoors.
Nearly anything capable of holding water, be it natural or manmade, is a potential breeding ground for mosquitoes. Rain or irrigation water falling on leaves, palm fronds, and other yard debris creates small pools where mosquitoes lay eggs to reproduce. Keep the yard neat to eliminate this problem. In addition, don't leave pet dishes, furniture, candle holders, or other manmade items where they can collect water.
If you have a pond or other decorative water feature in your yard, you don't have to drain it to prevent mosquitoes from breeding there. The easiest solution is to treat the water with a larvicide that kills mosquito eggs. Treatment products such as Mosquito Dunks are suitable to use in ponds, birdbaths, and fountains because they are safe for fish, birds, and other animals.
If you keep fish in a pond, you may not need any treatment, as many common pond fish species, such as bass, goldfish, mosquitofish, bluegill, and catfish, eat mosquito larvae. Instead of treating water in birdbaths, it's better to simply empty and refill them with fresh water every few days—mosquito larvae hatch as ear four days. Plants that hold water should be treated or flushed with fresh water every few days.
Bromeliads have leaf axils that can hold enough water to support mosquito breeding. Treatments include bacteria that must be applied once a week and methoprene, a treatment that lasts for 30 days. Running an ordinary but preferably strong household fan is the most effective non-toxic way to keep mosquitoes away from you while you're sitting outdoors. According to Consumer Reports , a fan can reduce mosquito landings on your skin, that is up to 65 percent for those sitting near the fan.
An oscillating fan is best for covering a large area for multiple people, but even a simple box fan will do the job if you're sitting in the fan's stream. Some associate mosquito invasions with water, so you might also think this means swampy areas and relatively large bodies of water.
Some spread diseases, such as Zika and West Nile viruses. Citronella oil is used in many different forms—from tabletop candles to oil diffusers to 5-foot tiki torches—to attempt to keep the pests at bay. A mosquito interprets the world through multiple chemical receptors, according to Laurence Zwiebel , a professor of biological science and pharmacology at Vanderbilt University. Here are a few more:.
