Summer is coming. There are not only cool and refreshing iced drinks and all kinds of artifacts to cool ourselves. Presumably, when we sleep in the hot summer air-conditioned room, there are always two or three blood-sucking mosquitoes buzzing in your ears. It's time to slap your face. It's crazy to find it and not find it! The next day we got up with all kinds of red spots on our arms, legs and faces. At this time, we really need a product that can actively kill mosquitoes and passively attract mosquitoes.
