Robotic insecticide
From MediaWiki

Robotic insecticide is lethal to Insecticons. It is, of course, completely harmless to all other Transformers and there is absolutely, positively no cause to worry about it. Its use may or may not be restricted to cloned Insecticons. Whether this means it is lethal to Cyclonus is debatable, but then again, so is the origin of Cyclonus, for that matter.
At least one brand of this bug-destroying substance found on Floron III comes in Bumblebee-sized giant red cans marked with Xs.
Skids understandably has his doubts about robotic insecticide. Quest for Survival
Notes
- The effectiveness of robotic insecticide may be questionable, as Kickback declared in "A Plague of Insecticons" that there is no spray capable of stopping the Insecticons. Of course, it is also possible that Kickback simply was unaware of the existence of robotic insecticide. Can you blame him, though? (It can also be speculated that robotic insecticide had not yet been invented.)
