“Cockies will go in while they are new. I kill them each morning and remove as much of the bodies as I can. Very cruel to leave them there stuck till they starve to death. However, it seems the cockies won’t go back once they smell the remains of their now deceased family members. This could be an expensive exercise replacing the trap after each cocky. However, I discovered putting cellotape over the remnants of the bodies seems to do the trick. It hides the smell.”
“I can control the large black cockroaches but these work on the harder to kill small ones along with boric acid. Have been using them for a few weeks now in my kitchen and haven't seen any live ones. thanks”
