Where should I put the mosquito-repellent incense?

Excuse me, where is the mosquito-repellent incense safer for the body? It's best to put it in the corner and know when it's best to light mosquito-repellent incense. (including electric mosquito coils, etc.). Mosquitoes are most active at two times of the day, one is dusk, and the other is dawn, especially at dusk, when doors and windows are open and people come and go, mosquitoes can easily get into the house. Therefore, mosquito-repellent incense can effectively repel mosquitoes at dusk.

In order to prevent mosquitoes from developing drug resistance, it is best to have 2-3 mosquito repellent products and change them every 10 day. The effect is very good.
