Purchasing was easy,delivery was fast and efficient but products are just a waste of money,the repellent is meant to kill/trap mosquitos andinsects according to my understanding but wow the mosquitoes/flys will just roam around the room with the repellent

Purchasing was easy,delivery was fast and efficient but products are just a waste of money,the repellent is meant to kill/trap mosquitos andinsects according to my understanding but wow the mosquitoes/flys will just roam around the room with the repellent not making any difference. Please recommend what really works/kills because I’m unhappy 😞
