You've been given very good advice.
Provide your budgies with areas to go and things to play with and that's where they will spend their time. If they have nothing to occupy them, then will find something to do.
It's a natural bird instinct.
I have a play area set up over my birds cage where they have all their toys, swings etc and they love to spend time there.
If there's an area I don't want them to go I make it so it's not accessible to them.
Take down items you don't want the birds to chew or cover them up.
Also you re very lucky that you had spider plants that the birds chewed, as these are non-toxic for them and are safe to eat.
All the plants I have are safe for my budgies to eat.
I also buy potted herbs for the budgies and let them chew as much as they want too.
The more you provide for them to stimulate their natural tendencies, the less you will see the 'destructive' behaviour.
Coping your female up won't help her. I share a bedroom with 13 budgies and I can tolerate the noise they make very easily.
