BBot - The best bot of the world

hello, i have problem. I use bot on walls, but when I'm going through a lizard city and the bot will get trap returns to dp or exp. When Lizard Legionnaire or Lizard Dragon Priest stands on mine SQM bbot returns to dp. When he goes to refill and will stay trap returns to exp and he dies. Maybe it's a solution?

PS Sorry for my eng
PS2. I have an option selected "Avoid" but it does not help
