Does it work during the day when the torch is not lit to kill flies ?

Hi Juliana. Thank you for contacting us and for being a valued PIC customer. The torch charges during the day and come on at night. It will not work during the day because the bugs are attracted to the light from the torch and when it is daylight they cannot see the light from the torch. If you have further questions, please contact us at customercare@pic-corp.com
