Matters needing attention
Cordate telosma, lavender, oleander, camphor tree, etc. Because their leaves give off some special smells, they have a certain effect on repelling mosquitoes, but these plants also give off substances harmful to the human body and are not suitable for keeping indoors; Nepenthes, on the other hand, rely on hinges to "eat" mosquitoes and do not have the ability to repel mosquitoes;
Although geranium and other new mosquito repellent plants are non-toxic and have certain mosquito repellent effect, the effective mosquito repellent area of 20-30 cm crown is only 10 square meter, so it is unrealistic to rely entirely on it to repel mosquitoes.
