Cazadores are a new predator in the Mojave Wasteland and often fight with Night Stalkers over their prey.Fallout: New Vegas loading screen

Cazadores are mutated insects found in the Mojave Wasteland, Big MT, Zion Canyon and in Fallout: New Vegas.[1]


Dr. Borous states that cazadores are the offshoot of DNA experiments performed in 2003 at Big MT.[2] Formerly, cazadores were confined to the Z-14 Pepsinae DNA Splicing Lab in Big MT, but groups of cazadores had escaped the Big MT crater and moved to neighboring areas, such as the Mojave Wasteland and Zion Canyon, in recent years. Doctor Borous denies that they have escaped from Big MT or can breed, which is shown to be false.[3]


Cazadores have a quick and erratic flight pattern. They are most often encountered in swarms of four or more, with the occasional strays flying in the outlying area. Their venomous attacks can lead to a quick death if they succeed in poisoning their target. The spikes on their back rise and fall, both when idle and when attacking.

Cazadores are more common in mountainous regions of the Mojave Wasteland, although some swarms can be found near lakes in lower areas. They create large basket-shaped nests, many of which can be seen at places such as Bonnie Springs, Cazador Nest, west of the Brewer's Beer Bootlegging, the road heading towards Jacobstown, north of Goodsprings, inside various tents in the Tribal Village and the boathouse at Callville Bay. The cazadores' original breeding ground is the Z-14 Pepsinae DNA Splicing Lab in Big MT. They compete with Nightstalkers for prey.[4]

A sting will do more physical damage than a giant radscorpion and cause three times more poison damage over a longer time. Crippling a wing via V.A.T.S. greatly slows them down and also temporarily disables their ability to fly. However, they will continue to sputter towards their enemy at a fast rate. Crippling their antennae will frenzy them. They do not take extra damage from shots to the head.

  • Companions are vulnerable to cazador attacks, as they cannot use antivenom. Stimpaks must be administered via the companion wheel. Companions will, however, use Datura Antivenom if they have any in their inventory.
  • Patch changed the cazadores' poison effect on normal mode. The duration is now shorter, but the damage is higher.
  • The cazadores found inside Big MT are tougher and drop significantly more poison glands than their Mojave counterparts.
  • Unlike radscorpion stinger attacks, which will always poison the player, getting poisoned by cazadores appears to be random, i.e., getting hit by their stingers does not guarantee being poisoned.
  • Cazadores have one of the highest base Perception of any creature, being higher than that of the common Deathclaw. This, coupled with their erratic movement behavior while idling, makes them nearly impossible to sneak past.


Cazadores appear in Fallout: New Vegas and its add-ons Honest Hearts and Old World Blues. They are also mentioned in the graphic novel, All Roads.

Behind the scenes


  • PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 It seems to be possible for cazadores to fall through the map and fly about under it. This will drive companions crazy, since they will target them but be unable to hit them. Affected cazadores cannot sting non-player characters or the Courier, but will continue to fly back and forth attempting to attack. If the player is above an affected cazador its name and health bar will be visible, but the cazador itself will be invisible. This is a clear indicator that the cazador is bugged in this manner. Attacking with the Ranger Takedown maneuver may fix this bug.
  • PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 Poison does not appear to wear off companions in the patch after combat. Dismissing the companion and re-hiring them at their home location or the Lucky 38 seems to bypass this. It will wear off after 30 seconds, administering stimpaks to companions will cause the whole damage-over-time to be applied at once which could bring them to negative HP.
  • Xbox 360Xbox 360 Sometimes (or all the time, if your system is affected), if cazadores are in the area, even if you can't see them, you will hear the poison hissing sound loud and close as if you had been poisoned by them. Essentially, you will hear the sound when a cazador anywhere in your active cell poisons something - the attack might not be on the player character or a companion, since even a distant cazador battle will trigger the sound.
  • Playstation 3Playstation 3 Xbox 360Xbox 360 If you use the Flamer against them, they sometimes freeze in the air while on fire.
  • Playstation 3Playstation 3 Xbox 360Xbox 360 Rare occurrences of cazadores being able to poison you when they are in no way close enough to do so, seems to only happen in V.A.T.S.
  • PCPC Xbox 360Xbox 360 Sometimes, the legendary cazador just wanders around the cave without attacking the player.
  • Xbox 360Xbox 360 In Silver Peak Mine, cazadores may not show up as red blips on your heads-up display even though they can be targeted using V.A.T.S.
  • Xbox 360Xbox 360 Sometimes, cazadores may appear in the Followers Safehouse.
  • Xbox 360Xbox 360 Due to their incredible speed and relatively small size, cazadores can easily embed themselves into rock formations to make themselves harder to hit, lure melee focused couriers towards them and unlike most enemies even slow the framerate of the game to a crawl, making their fellow cazadores even harder to hit. This effect appears to stack depending on how many cazadores there are inside any number of rocks at one time and is hit and miss on whether looking away from the cazadores helps the framerate or not. Standing around appears to make them leave the rocks and attack the courier directly.

  1. Red Lucy: "We've got three fiends ready for our Cazadores."
    (Red Lucy's dialogue)
  2. Courier: "All right... when did you create Cazadores?"
    Doctor Borous: "In... two thousand... let's see, carry the three... then count backwards from the Great Static... or beyond? There were the tarantula debates... and something about hawks, which made it around... eh, 2003? May? Tuesday. It was definitely Tuesday."
    (Doctor Borous' dialogue)
  3. Courier: "You are responsible for Cazadores?"
    Dr. Borous: "Indeed. Docile. Curious. Safe. Sterile. They are contained here at Big MT to preserve DNA and for observation."
    Courier: "Contained at Big Mountain? Those things are all over the Mojave!"
    Dr. Borous: "No, such creatures are found only here, for research purposes. They would no more be capable of escape than breeding."
    Courier: "What makes you think they haven't escaped?"
    Dr. Borous: "Because Big MT's safety measures are far more sophisticated than their primitive animal instincts. WE are their lords and masters."
