Mod from Fresno, California writes,
what works better on German cockroach, tempo wp or demon wp?
Tempo Ultra WP and Demon WP are both labeled for various types of roaches. They have two different active ingredients in them, which is the main difference. We would not recommend using just one product to control roaches. A bait gel and IGR (insect growth regulator) should be added to ensure that you are maintaining control of the roaches.
