Do aspen erosion control blankets really let grass seed grow through, AND what about harvester ants?

I have lots of disturbed dirt I want to return to native grassland. I have a grass seed mix native to my area (Trans-Pecos Texas), but I've watched harvester ants walk off with my well spread seed, even with jute and with tackifier (separately).  I'm now looking at those aspen-wood erosion-control blankets. Online promotional stuff says they do let grass seed grow up through it nicely, but I'm wondering if I'm just making an ant pergola with another buffet for them.  Part of my wanting them is also erosion control... I'm helpless watching lots of silt and mud and sand move downslope from the recently disturbed areas, with our recent rain, and bury the native grass... In past years I've seen this kill the grass.

It's been raining so much here, anomalously, allowing me to pull goatheads, tumbleweeds, and amaranth so easily, and while I'm doing that I've been poking my fingers into the mud (which is rarely so wet,) dropping a few individual grass seeds, and smooshing the mud over the hole. And even watched an ant go for one before I buried the seed! But boy do I not have time or energy to do that for the ~1/2 acre I need to.  I could certainly zen out on that in half hour breaks over the next week while we still have this tropical storm system, but I'm still watching a lot more dirt move than I want to move, so i still need an erosion solution, and am hoping to grow grass from seed while I stop the dirt movement.

Does anyone have experience with these things?

I have never used those aspen-wood erosion-control blankets so I cannot answer that question.

What I can say is that I would not expect the blankets to stop the harvester ants.

I have a foam mat that I use to smother grass that is about 1 inch thick.  The harvester ants just walk right under that mat.

I can also tell that the grass I am trying to smother was planted by the harvester ants so there might be some hope that not all that seed is lost.

I would follow the planting instruction that came with the seed mix then walk over so the seed gets good ground contact.

Best wishes.

Good idea to walk on it, especially while we're having rain and it's muddy. I think I'll spread seed, walk on all of it, then lay jute fabric to keep that dirt in place.
