Wait, I thought that Astartes were well knowledgeable about the existence of Daemons and Chaos in 40k. I know such knowledge was not available during the Great Crusade and is kept from the masses by the Inquisition in modern 40k, but I thought Astartes would have full knowledge of the threat, especially those around the Malestrom and Eye of Terror.

I know Grey Knights are the 'counter' to Daemons, but they have somewhere around 1,000 troops at one timedon't they? They don't show up unless the situation is absolutely dire from my understanding, such as when Angron emerged from the Warp and killed 100 of them by his lonesome. So, I figured that in most cases of minor Daemonic incursions, Grey Knights wouldn't be deployed but the planet would simply be marked for exterminatus due to even a minor daemonic infestation being impossible to stop once it has begun.

As for weapons working against daemons, I recall from a book from the HH novels that flamers and blades have a good chance at hurting/killing daemons should Nemesis-Psi weapons not be available since the "archaic" nature of the weapons have some kind of connection to the Daemons existence.
