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

Field Testing PPE

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 cant 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.

18
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 ambulance .

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?

20
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.

21
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. Dont forget to tell them afterwards.

22
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.

Subduing Bee Attacks
UF / IFAS
25
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.

27
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.

28
Arizona Recommendations
  • 1½ hose line
  • 200 psi at 95 gpm
  • AFFF with a full fog pattern

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.

32
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.

34
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.

35
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)

36
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 dont have the time or man-power to
    eliminate nuisance feral bee colonies. Where do
    we draw the line between threat and nuisance?

37
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.

38
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
  • allergic reaction, which could be fatal in less
    than 30 minutes,
  • toxic response from a massive envenomation, 5-10
    stings / lb. body wt. is potentially lethal.
  • infection, which is more common and normally less
    serious.

40
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

41
First aid prior to arrival
  • In the case of an allergic reaction (anaphylaxis)
    paramedics will initiate Advanced Life Support
    measures in accordance with their Departments
    Standing Medical Protocols

42
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

43
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

44
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.
