Mini-FOT LogoThe following is based on Fallout Tactics and some details might contradict canon.

A giant mutant strain of ladybug with unstable body chemistry. Explodes when agitated, disturbed, angry or bored.

The Boom bug is a thrown explosive in Fallout Tactics, in the Midwest of 2197. Boom bugs are mutant ladybugs that have a tendency to explode.


Boom bugs are pretty much worthless compared to frag grenades, but the lack of grenades in the early stages of the game makes them more viable. Boom bug explosions can poison targets. They explode in a buggy, toxic mist that damages all targets within a 5 hex radius.


  • They can be found in large quantities (100+) on the dead bodies of the tribals at Peoria, where your mission entails retrieving 3 fusion batteries.
  • The hostile 'Beastlord' faction almost always carries a few Boom bugs with them in their war parties. This is on account of their use of animals and other nature-oriented weapons in combat.
