I need your thoughts and opinions on dried insect mixes please. If I want to give my waxbills the best chance next season, I need to increase their bug diet

Live mealworms I have going already but as to termites etc, I just dont have the time or resources to go hunt down termite mounds in the mountains (would be fun though, lol!) I have found the below make which I can import from the UK but before I do, I would like your opinions as to whether or not it is worth it.
Any success stories with these type of mixes? Do the birds accept it easily?
