Changing my Fantasy Pacman frog from a staple diet of crickets to nightcrawlers

[Misschievou2]

Prince Charming II is currently eating about 6 - 14 crickets a day - He is a very good eater! No problems with that! Ain't he the cutest little Fantasy frog you've ever seen? I adore him . I believe he is around 4 - 5 months old.

But crickets are extremely annoying. They are:
+ Hopping everywhere and easily escape my grasp - I have a few running around my room and I am very upset about this.
+ When they get older they make a lot of noise.
+ They die very easily in my container I have for them and they stink very badly. Feces and urine everywhere on there food.
+ Incredibly hard to clean the crickets cage without one or two escaping me. VERY annoying.
+ He eats a hold bunch of them now - it is probably easier to use bigger victims!
+ My dad is actually very upset they are in the house. I tried to explain to him that they are not cockroaches but he is stubborn to his ways.

I have a few questions about nightcrawlers. I heard they are great staple diet. By the way - The ones that I have access to are undyed, no pesticides added and no additives of any sort. I spritzed there containers with de-chlorinated water to be extra sure they are not in chlorinated water.

Questions:
1) Petco tells me they make a terrible staple diet. But on this forum people rave about nightcrawlers. Anyone out there have a frog that is healthy and eating nightcrawlers?
2) How do you feed your lovely froggie a nightcrawler without the nightcrawler ducking for cover in the dirt? ( see first picture of worm hiding)
3) What is the best way of changing a staple diet from crickets to nightcrawlers?
4) Do you think my frog is too small to eat the night crawlers I picked up? (see picture of frog the size of two quarters and nightcrawler)
5)What do you think about adding calcium to the bath instead of coating the food? .
