Help with purple deadnettle weeds

[CalvertNewbie]

These weeds are all over our garden beds and are starting to spread into our grass. I've been busy pulling them out but it looks like I've barely made a dent. Someone mentioned that I'm wasting my time pulling them. He said that I should just use weed killer, lay down landscape fabric, then mulch the garden beds. I thought I would need to get rid of them first, then put the landscape fabric down.

- Will that be enough to kill them?
- What is the best weed killer for purple deadnettle? There are so many options out there and I want to buy the best one.

TIA!

Fabric works well, lasts a few years then needs to be replaced.

Spot use Round Up carefully on them, and once there gone, retreat periodically with liquid 2-4-d, if any more weeds pop up...........

Thanks, Toppick! So the guy I spoke with was correct in saying I don't have to pull anymore of them, just spray them? That'll make things a lot easier. I'll be running out to the store today to stock up on a lot of Round Up and some 2-4-d.
