i have maggots in my bin and have tried to use boiling hot water and keep the lid shut but they keep coming back. i have heard that they can crawl through your brick work and nest in your materess so im s#!t scared now!!!
maggots are baby flies. if the flies cant get in to the bin to lay them because the lid is shut what is the problem?
ps, they dont last long as maggots and IF they got into your mattress, which I find highly unlikley, the worst that'll happen is they turn into flies. Someone's trying to freak you out. I'd chill about them getting in your mattress!
