AS - Yay for praying mantis!
Perhaps next year you can release a few extra? You can buy their egg cases.
Is your patient work offering them water to drown themselves in (that is pretty funny that they will do that) not reducing the numbers any?
Is there a trap crop you can use to lure them away from your food plants?
Here's a little bit from an article about that:
Small plantings of species such as triticale, sunflower, sorghum, millet, buckwheat, soybean, field peas and okra, provide superior food plants for the bugs while also attracting their natural enemies. Sorghum, millet, triticale and buckwheat are amenable to ratooning, i.e., mowing, to change crop phenology. This characteristic can be exploited to better manage and extend the timing of the trap crop attraction versus the cash crop, hence prolonging the efficacy of the trap crops and reducing the cost of trap crop reestablishment....Buckwheat is planted because it is easy to obtain and culture, grows quickly and is highly attractive to stink/leaffooted bugs when in seed. The flowers also provide pollen and nectar to bees and wasps as well as tachinid fly parasitoids of stink bugs. Okra, field peas and sunflowers also provide nectar and pollen or alternate hosts (aphids, whiteflies, mites) for beneficial insects, as well as vegetative structures and large seeds attractive to stink/leaffooted bugs. Millet and sorghum provide highly attractive seeds.
