Fallout – Why is the Repellant Stick exploding other creatures

fallout-3

Playing Fallout 3 after finally getting around to buying it and I've gotten the repellant stick. Then I go to do the Robco mission, which is just filled with things to hit the with a stick, and every single radroach I've smacked has, without fail, exploded. I know I have the perk which causes things to occasionally explode but from what I know it shouldn't be this consistent. I checked the wiki to make sure it was the stick, and it wasn't just mole rats that explode, but the wiki insists it really is just mole rats that explode when hit with the Repellant Stick. Is my game being retarded or am I just getting the weirdest luck with my explosion perk?

Radroaches are just fragile in general. It may just be a coincidence.
