Well, alien zombies, maybe.
Which is exactly what would happen to the OP seven months later. 
Introducing a non-native species to control another introduced pest is bloody dangerous.
Exhibit A, the Cane Toad.Cane toad - Wikipedia
We bought a batch of chicks [25 as I recall] and raised them along with our chickens - the whole bunch get let out in the morning, and put back in the coop at night. They all use the same waterers and feed. They all go about their birdy business scratching around, chasing bugs and squabbling amongst themselves. Of course the eagles in the woods catch them both [chickens and guineas] with regularity and we have to restock on birds every couple years. And racoons will try to break into the coops. And we just spotted a fisher cat [from the batch that Massachusets released on the MA CT border a bit back] about a mile from the house and have been hearing it and coyotes in the woods, so that would also explain the occasional loss of birds.
I like Murray McMurray Hatcheries - they always arrive alive, the one time that we had one batch arrive with 2 or 3 chicks dead they gave us back the price of the dead chicks [there is a minimum number of chicks that can be shipped, to keep them all warm enough to survive shipping.] Frequently Agway or another farm supply store will take orders for assorted types of chicks in the spring, and we have adopted an occasional chicken from a local egg factory looking to get rid of old hens [they still lay eggs, just not at peak production and often make decent pets if you only want 2-4 hens though I wouldn’t add in a rooster, they are not used to being bred and tend to get stressed out.]
Adding guineas as an ‘invasive species’ is sort of silly, they slot into the feral chicken population as chow for apex predators - and chickens are also an invasive species FWIW, having originated in southeast Asia.
It helps that guinea fowl are very, very tasty, but I’d characterise their danger call as “a repetitive rusty gate hinge that goes on forever”, so there’s that.
For a second there I thought you were talking about the Asian/Japanese Giant Hornets, “the yak-killer”. :eek:
Now that this thread has been revived, I am curious. What is the current stink bug situation relative to a couple of years ago? Did they ever try the wasp solution?
No problem. We simply release wave after wave of Chinese needle snakes. They’ll wipe out the Asian Wasp.
And after that, we’ve lined up a fabulous type of gorilla that thrives on snake meat.
And here’s the beautiful part! When wintertime rolls around, the gorillas simply freeze to death!
do like I do - put up purple martin houses.
from what I have read, PM’s eat stink bugs. However, I was disappointed to learn that PM rarely eat mosquitoes, only because they are out at opposing times of day. Even so, I never have mosquitoes, so i debate that.
PM’s require a human host to build an apartment for them, or they will not stay.
So please host a PM congregation. Go to Lowes or Home Depot (or better yet, go to an Amish store) and buy a nice PM house and a 12 foot telescoping pole. They also like those white plastic PM homes from Walmart that are gorde shaped, but the have only one door / room…a $50 apartment from Lowes or the Amish can have 16, 24 or 48 apartments.
Mine just started moving in this week, from the winter (Southern Indiana). So get it built ASAP.
PS buy a bb or pellet gun to blast the sparrows and sparlings - they will try to evict PM’s and even kick out their eggs.
I can tell you for 3 years now I have only bees flying around my property. And i enjoy watching the PM’s dive bomb for insects. They actually buzz right in front of me as I am riding on my riding mower, getting every bug that I stir up.
A two year old joke! 
I’ve got as many this year as I did last year - I’m killing between 10 and 20 a day in my house - so if they did release that wasp, it’s not working!
I’m waiting for the inevitable SyFy movie. That will be the true tragedy.
