it depends on the size of cricket from my experience like the adult crickets can jump and reach the lids or in your case just jump out i think medium sized crickets could but small or baby probably couldn't. Crickets are very good at escaping if you frog gets big enough you could try to swap him/her to Nightcrawlers aka earthworms i got money those won't jump out :P just make sure they are pet safe nightcrawlers and not fish bait nightcrawlers
