I have to say my tanks where the frogbit explode are the ones with higher bioloads &/or the ones where I skip water changes more often. It is possible that a humid environment (lidded tanks) also helps, and keeping water circulation lower is definitely helpful. My dirted tank with a sand cap exploded with frogbit first, so I think doing a little dirt (I would cap it) would be a great route to go. After that, my other planted gravel tanks started getting a ton of frogbit when I quit doing weekly water changes. To be honest, I'm throwing away bags of the stuff every month now -- except in the 2 tanks that both have no lid...and also bad lighting I'm just realizing, so maybe that is the problem there?
In any case, I'd suggest putting a few ramshorn snails inside to create some waste, then drop in a tiny bit of an algae wafer occasionally -- once a week maybe? I also have baby shrimp in my jarariums -- when I clean the filter I rescue tons from my cleaning pails and just pop them into the jarariums instead as they're on the desk where I'm working. Then don't bother with water changes except one every several months. Otherwise I just top off when needed. I personally have tiny sponge filters in my jarariums but I don't know if they're necessary...
It's not a mystery...snails are the BEST!
