                 Africanized Honey Bees




W. H. Kern Jr.
  Africanized Honey Bees
• Same species as the European
  Honey Bee
• The sting has the same toxicity as the
  European Honey Bee
• AHB and EHB can not be told apart
  by looking at them.

               Swarms
• Are a way for colonies to divide when they
  get too large for the hive location
• The old queen and some of the workers
  leave the old colony to found a new colony
  at a new location.
• These bees are not defensive because
  they do not have resources (honey and
  babies) to defend.
• Even Africanized bees are not very
  defensive at this stage.
 Swarms Are Not Aggressive

                      is present
                     expect bees
                     to be VERY
                     DEFENSIVE.
                     This is not a
                        swarm!

                  PPE
• Bee suit with zippered veil and bee gloves.
• Bunker gear with Bee veil taped around
  edge of veil with Fire fighters gloves.
• Chemical spill Tyvek suit with bee veil and
  double layers of latex gloves.
• Brush land suit, veil and gloves.
• Always –eye protection glasses, goggles,
  or face shield under veil so bees can’t
  spray venom through veil into your eyes.
Bee suits with zippered veil and bee
 gloves are the best protection.

            Secure the bottom
           edge of jacket with a
          belt or duct tape kept
          bees from climbing up
             under the jacket.
             Sleeve cuffs are
            usually effective at
            keeping bees out.

     This configuration provided adequate
    protection, but limits vision and was hot
               and cumbersome.
      Have absolutely no skin exposed.
                                   Do not wear a
                                   helmet if it is
                                   safe to do so,
                                   because bees
                                   will get under
                                   helmet and be
                                   carried to the
                                   engine or

      911- “Bee Sting” Situation
             Evaluation
•   Is someone being stung now?
•   How many victims?
•   Location of Victim and the Bee Colony
•   Call back number
•   Are there any schools, day care
    centers, nursing homes, or businesses
    within 300 yards?
 On Site Situation Evaluation
• Turn off Lights and Siren prior to
  approaching the victims location.
• From inside closed Recon vehicle
  – Identify location of all victims.
  – Is this a swarm or a colony with comb?
  – Try to identify the location of the bee colony.
• Stage engine about 150 ft. from the victim
  and bee colony.
• Stage ambulance at least 150 yards away
  from situation.
           Warn Bystanders
• Advise the people in homes and businesses
  neighboring the incident, to remain indoors and
  bring in pets until the incident is concluded and
  the colony is eliminated.
• Swarms will rarely become defensive, but an
  agitated colony may attack anyone within 150 ft or
  more.
• Advise schools, day care centers, nursing homes,
  recreation centers within 300 yds of the incident to
  keep everyone indoors until advised that it is safe.
  Don’t forget to tell them afterwards.
In Route to a Stinging Incident

Everyone that will get out of any rescue
vehicles within 100 yds of the stinging
incident must put on PPE, including
gloves, bee veils or face masks and
hoods. AHB will attack anyone within 150
feet or more of a disturbed colony.

                        • Locate all victims
                        • Locate bee colony
150 ft.
                        • Direct rescue efforts
                        • Evacuate victim

           Recon vehicle should be
           as close as possible

           Choice of Foam
• AFFF – Aqueous Film-Forming Foam is
  recommended by Arizona F.R. Depts.
• Class A Foam is an acceptable substitute
  at 2-5%.
• AFFF foam kills bees within 60 sec and
  knocks them down immediately by wetting
  them.
• Plain water will only knock bees off
  temporarily and will not normally kill them.

     Approach Recommendations
•   Aqueous Film-Forming Foams (AFFF)
•   A quick attack 1-3/4" hose line will be
    pulled and hooked to the apparatus
    AFFF foam system. The hose line will be
    pulled by the firefighter at a quick pace
    towards the affected patient, with a full
    fog pattern on the nozzle -- sweeping the
    air surrounding the firefighters and
    patient.
Arizona Recommendations

• 1½ “ hose line
• 200 psi at 95 gpm
• AFFF with a full fog pattern
 ¾” line with integrated foam
equipment using Class A foam

    Transport the Victim to the
           Ambulance
• Do not have the Ambulance come into the
  incident area unless the EMTs have
  appropriate Personal Protection Equipment,
  especially veils.
• While transporting the victim to the
  ambulance, try to brush or wash away as
  many of the bees as possible from the
  victim and the rescuers. This will protect
  the EMTs and make it easier for them to
  treat the patient.
        Securing the Scene
• After the victims have been evacuated, the
  defensive AHB Colony must be destroyed.
• AHB will continue to be highly defensive
  for up to 24 hours after the initial
  disturbance. They will attack any person or
  pet within 150 feet of the colony site.
• Pest control professionals are usually not
  prepared to subdue an agitated, highly
  defensive bee colony.
• Destroying an agitated colony is essential
  for public safety.
           Danger Zones


150 yds.
                 150 ft
             Securing the scene
•   The AFFF will kill the AHB within
    approximately 60 seconds of contact.
•   The AFFF will be used to kill the colony
    after patients have been rescued. The
    same sweeping motion will be used to
    approach the bee colony completely
    flooding the hive with the AFFF hose line.
•   Class A foam will kill honey bees if AFFF
    is not available.
        Securing the Scene
• Option One.
  – Find and destroy the defensive colony with
    foam if possible. (colonies in trees, bushes,
    debris, non-electrical location, playground
    equipment, etc.)
• Option Two
  – Quarantine the site, asking people to stay
    inside and bring pets inside until a licensed
    pest management professional arrives to kill
    the colony with insecticides. (especially
    colonies inside buildings or electrical
    equipment)
 How do we keep firefighters out
  of the pest control business?
Situation 1: Homeowner calls 911 about bee
  swarm or feral colony? No one is being stung,
  then no emergency so refer to a PMP.
• Situation 2: People stung and trapped inside
  structure, do the firefighters just get the people
  out or do they eliminate the threatening colony?
  Should AHB calls be treated like a hazardous
  chemical spill with a charge levied against the
  property owner? An agitated AHB colony is a
  public safety threat. But fire departments don’t
  have the time or man-power to eliminate
  nuisance feral bee colonies. Where do we draw
  the line between threat and nuisance?
                     First Aid
• Bees leave behind a
  stinger attached to a
  venom sac. Do not try to
  pull it out, as this may
  release more venom.
  Gently scrape it out with
  a blunt-edged object,
  such as a fingernail,
  credit card, or dull knife.
  Wash the area with
  soap and water.

                   First Aid
• Apply a cold or ice pack, wrapped in
  cloth for a few minutes. Apply a paste
  of baking soda and water and leave it
  on for 15 to 20 minutes, treat with a
  “sting swab” or dab on a bit of
  household ammonia. Take
  acetaminophen for pain.

             First Aid
• The three greatest risks from insect
   stings are
1. allergic reaction, which could be
   fatal in less than 30 minutes,
2. toxic response from a massive
   envenomation, 5-10 stings / lb.
   body wt. is potentially lethal.
3. infection, which is more common
   and normally less serious.
      First aid prior to arrival
• Seek emergency care if you have any
  of these symptoms, because they
  indicate an allergic reaction:
  –   Large areas of swelling
  –   Abnormal breathing
  –   Tightness in throat or chest
  –   Dizziness
  –   Hives
  –   Fainting
  –   Nausea or vomiting
  –   Persistent pain or swelling
      First aid prior to arrival

•   In the case of an allergic reaction
    (anaphylaxis) paramedics will initiate
    Advanced Life Support measures in
    accordance with their Department’s
    Standing Medical Protocols:
      First aid prior to arrival
• If anaphylaxis without hypotension:
   – If wheezing, administer Albuterol 2.5-5 mg via
      nebulizer
   – May repeat PRN
   – Administer Diphenhydramine 25 mg IV/IM
   – Consider Methylprednisolone 125 mg IV or
      Dexamethasone (Decadron®) 25 mg IV
   – Epinephrine 0.3 mg IM/IV
         First aid prior to arrival
•    Anaphylaxis with hypotension:
    – If wheezing - administer Albuterol 2.5-5 mg via
       nebulizer
    – May repeat PRN
    – Administer Normal Saline bolus of 20 mL/Kg to
       maintain systolic BP greater than 90 mm Hg
    – Administer Diphenhydramine 25-50 mg IV/IM
    – Administer Methylprednisolone 125 mg IV or
       Dexamethasone (Decadron®) 25 mg IV
    – Administer Epinephrine 1 mg in 10mL IVP
       every 3 minutes to a total of 5 mg over 15
       minutes
   AHB and Your Profession
• You may never have to rescue a victim
  from a large defensive colony in your
  entire career.
• AHB colonies in trees impacted by
  vehicles and inside structures, may
  become common hazards in Florida.
• AHB colonies in public playgrounds, parks,
  and schools may be added to your scope
  of work.
