10 Natural Mosquito-Repellent Plants

Summer means mosquitoes. While there is no doubt that mosquitoes have an important role to play in the ecosystem, they are a pest to humans and pets, and none of us wants them around our homes. They are a great food source for bats and birds, however, they also bite, buzz persistently, and carry serious diseases. These include Malaria, ZIKA virus, Ross River Virus, and others.

Using bug sprays which contain DEET is not ideal. It can be toxic, especially in large amounts and when used by children or pregnant women. There are now some commercial insect repellents available which do not contain DEET.

The good news is that there are natural ways to repel mosquitoes, without using environmentally harmful insecticides and bug sprays. One of these is by harnessing the power of plants which naturally repel these annoying little insects.
