You're on the right track with Gentrol and Advion Arenas, but large roaches (like American cockroaches, aka "water bugs" or "palmetto bugs") require a more tailored, aggressive strategy. Here's a breakdown to help you build a full "roach army" for knockdown + control in an apartment Texas or anywhere.
1. Gentrol Point Source or IGR Spray (Insect Growth Regulator)
-
Effectiveness: Excellent long-term control. Doesn't kill adults directly but prevents reproduction and disrupts development.
-
Keep using? YES. It's a vital part of the "sterilization" effort. Just know it’s not a knockdown product.
2. Advion Cockroach Arenas (bait stations)
-
Effectiveness: Good attract-and-kill bait. Roaches feed and bring poison back to the nest.
-
Drawback: May not attract American roaches as effectively as German roaches. American cockroaches are usually controlled outdoors, not indoors unless they are infesting walls, cabinets, appliances, etc.
-
Upgrade/alternate? YES — consider rotating with or switching to Vendetta Plus or Vendetta Regular Cockroach Gel Bait .
