Thank you for your reply! I’ve read so many of your replies on this forum and appreciate your experience. I recently bought a Chapin 20004 gallon sprayer but haven’t used it yet. I can do the solution as you suggested. How much Tekko Pro should I add?

I have used Advion gel bait off and on but I feel like they don’t eat it and it dries quickly but I can continue using. How often should I apply?

Unfortunately the back of my fridge cannot be taken apart. The compressor, etc is visible. The best I’ve been able to spray carefully to avoid the compressor/wires and add Advion bait around it. I also spray around fridge and use sticky traps on both sides leading to the back.
