Can hairspray kill gnats

Hairspray can kill gnats by suffocating them, as it contains ingredients that can block their breathing pores. However, it's not an effective or recommended solution for dealing with gnat infestations. There are more targeted and safer pest control methods, such as vinegar traps or insecticidal sprays specifically designed for flying insects. Using hairspray can also leave a sticky residue and may not address the root of the problem.
