So one of the upcoming mini-bosses in my campaign is a wihsaak sahkil - these guys get vomit swarm as an at-will spell-like ability (CL 8th).
To me this seems very OP - he can have up to 8 swarms going all the time, or 7 if he stops to make a full attack every now and then.
Am I missing some rule that limits summons, or some weakness of swarms? Otherwise I'm thinking of making it the SLA 3/day.

I think that a swarm of wasps, even one summoned every round, is something a party with access to magic could handle.
It seems nothing keeps him from summoning wasps every turn. If you want to balance it more, you could say that he can have only one summon at a time. However, it should be noted that swarms can't precisely occupy the same spaces as each other (the rules imply they don't, but in any event they would likely harm each other if they tried), and he's giving up his turn to call them, so that's him not using Droning Madness or anything else.

Vomit swarm is a standard action. At that level, it can summon a wasp swarm which is cr3. The swarm lasts rounds per level, so 8. If this thing knows you are coming before you get to it, it would likely start committing swarms before the fight. It does seem a bit strong for a CR 6 encounter. Basically, if you don't catch it unprepared, you should run away and try again later.

How many rounds do you expect the fight to last anyway? If it manages to get off 3 of these I would be surprised.
Yeah, that seems like the basic war of attrition whenever you face enemy spawners.
Ignore the swarms, and just attack as hard as possible. Of course, AoEs that target both are preferred, obviously.

Also, this is a flying monster that can summon flying swarms before a lot of classes have reliable access to fly.
Oh, wow. Yeah, that changes the dynamics here by a lot.
If it was ground based, then it would be simple- charge over, and then use full attacks (if available) until it dies. But flight makes things much harder to get ahead with the attrition.

Even if you can get close to it, it can emit 100 ft confusion aura that it can maintain as a move action, while vomiting swarms as a standard action. Also it's immune to swarms, so can stand in the middle of them. Also it has at will blur which lasts for 8 minutes a pop, so if it is even close to expecting combat that is probably active. And it has a gaze to cause Shaken. And it has DR and SR.....
This thing should be at least CR 7.
Edit: And it has at will greater teleport, so if you are beating it, it can just run away and come back later.

You vomit forth a swarm of spiders that attacks all other creatures within its area. The swarm begins adjacent to you, but if no living creatures are within its area, it moves in one direction of your choosing at its normal speed.
You can move the swarm or change the swarm's direction by spending a standard action to concentrate on the swarm, otherwise it continues moving in its current direction. If your caster level is at least 7th, you can vomit forth a swarm of wasps instead. Finally, if your caster level is at least 13th, you can vomit forth a swarm of army ants.
So unless it encounters a living creature (I guess the summoner counts) you have to pick a direction for it to move, and it continues moving that way unless you spend a standard action to change it. It doesn't move on its own, it only moves if you spend a standard action to move it. I guess you could point them all at the entrances to the room but that brings up the question I never did see the answer to, can swarms kill swarms? Will all the swarms kill each other?
Edit: Oh wait, even if the swarms don't kill each other they have to stop and fight each other. They're also "living creatures".

So a shadow demon situation, on steroids. A step below 'rocks fall'.

Still a one round action to Summon Swarm.
I was sure that all SLA were a standard action, but I'll be damned:
"A spell-like ability has a casting time of 1 standard action unless noted otherwise in the ability or spell description."
Nobody tell my players!
So that and the AoO make it quite a bit more costly for him to create swarms.

For funsies, this particular wihsaak has the swarmblooded template from Advanced Bestiary, meaning it automatically creates a wasp swarm whenever it bleeds, is slashed, is crit'd, or dies. >:D But you're right, it already has a slurry of defenses already, maybe the swarmblooded is overdoing it?
My hope is they use a bit of thinking in this battle, instead of 'bashy bashy done'.

Unlike a summon swarm, which will pursue or move towards the nearest living creature if none are in its area, the vomit swarm effect will only move in one direction. So, you can pretty much avoid it or its path. The controller can change this, moving it towards an enemy (or off of an enemy towards a different one if its got one in its area) with a standard action, which will otherwise hinder its abilities to do other actions. It also means it can pretty much only control one swarm at a time even if it vomits out multiple ones.
