MOSQUITO MYTHS
- You can repel mosquitoes with electric devices that emit high-frequency sounds.
FALSE - Scientific studies have repeatedly NOT shown that electronic mosquito repellers prevent mosquitoes from biting. In most cases, the claims made by distributors border on fraud.
- Electrocuting devices help reduce mosquitoes around the house.
FALSE - Bug zappers kill a lot of insects, but very few of these insects are considered pests. In fact, many of the insects killed are beneficial insects that would otherwise serve as food for wildlife. Comparison trapping have shown no significant difference in mosquito populations in yards with and without traps.
- Citrosa plants will repel mosquitoes.
FALSE - The Citrosa plant alone will not repel mosquitoes. The Citrosa plant is a household plant that produces citronella oil, which is known to have mosquito-repelling properties. Although the concept of the plant emitting such a barrier appears sound, the claims have not stood up to scientific testing. Tests conducted in Florida indicate that Citrosa plants did not reduce the number of bites received by test subjects. In fact, mosquitoes were found to land on the plant, indicating that the plants did not emit enough citronella oil to repel the mosquito.
- Bats will eat thousands of mosquitoes each night and therefore help control mosquito populations.
FALSE - Research has shown that insectivorous bats are selective feeders and mosquitoes make up a very small percent of their diet. They will typically feed on the larger insects. Bats diet will typically consist of the same type of insects that turn up in bug zappers. Bats can also harbor and transmit rabies. Bats are not an adequate means in controlling the population of mosquitoes.
- Purple Martins will eat thousands of mosquitoes each night and therefore help control mosquito populations.
FALSE - Purple Martins will eat mosquitoes, but they are selective eaters and will select the larger insect over the mosquito. Tests have shown 1% - 3% of the Purple Martin diet consists of mosquitoes. |
