Recommended products for IGR and traps?

Going diypestcontrol to buy Alpine WSG but I’m a bit lost on what specifically to buy for the IGR, traps, and anything else that isn’t Alpine WSG. Would I be able to get recommendations for brand/etc? I was looking into diypestcontrol’s “Ultimate German Roach Kit” but I wasn’t sure if I needed all of it/if I could get it for cheaper/if there are better alternatives out there. Thank you!
