Grounding a flying creature

[Chakfor]

What's the best way to bring a flying creature down to earth using non-blast spells or attacks? Just something that makes the flier unable to fly, but still able to defend itself.

In our last combat I used telekinesis to grapple a flyer and cause it to fall but that isn't going to be a tactic that I can rely heavily on since it's a concentration dependent spell.

For a little background, the wizard is level 9 and is a pure controller with no blasts at all. I let my party and summoned monsters do the killing. I just need a way to get flying creatures down to earth so my warrior and ranger minions can cut them into tiny ribbons.

Any other ideas?

Hold Monster? Though Telekinesis is better since it has amazing range and can be retried or used on other flyers from round to round.

This only works against things that use wings to fly and there is a fairly easy Reflex save to avoid it, but a tanglefoot bag will cause a creature struck to be unable to fly.

Grasping Hand works, but it is a 7th level spell (meaning level 13 to use it).

Iron Bands of Binding is an item that may help in this scenario (basically acting as Grasping Hand). Cost is 26K GP.

Black Tentacles works well if you can get them down to the ground first.

Anything that STUNS the target for a round should make them drop, since you can't take a free action (to hover or fly) if you are stunned.

Color spray is one (of many) options that can stun a target for a round.
