March and April typically mark the beginning of swarming season  for bees, a time when the bees will be moving from place to place. Warmer  weather and increased outdoor activity lead  to the increased possibility of  bee encounters.

What kind of bee is it? All bees in  the valley are referred to as “bees.” It doesn’t matter if they are European or  Africanized. Both bees act in the same manner. They sting the same way and both  produce honey. The only trait that is different is the sting potential, but   even European bees can produce enough stings to severely injure someone or   cause death. All bees should be handled in the same manner regardless of what  type they are.

Swarms of bees move from one  place to another. They get tired when swarming, and it can get too hot for them to fly.  So the bees will find a place to rest and get out of the sun. Many times,  they will hang from tree branches, street signs, fences, sides of buildings or  on an object like a fire hydrant. They just want to be left alone and to rest.  Because the swarm is not producing honey or caring for young bees, they will  not sting unless provoked, and then usually only in extreme cases. Usually, they  will rest for a few hours or until late in the afternoon or the next morning.  Because the bees are harmless, in most cases they are not exterminated. Safety  tape is put up to advise the public of the bees and usually they leave and the  tape is taken down.

Bee hives, especially those  that are wild, are where the danger lies. Bees will build their hive (their  home) in places where predators cannot get to them, such as inside sprinkler  control boxes, street light poles, utility boxes in sidewalks, inside walls of  buildings, inside concrete block walls and inside old hollow trees and desert  plants. When the bees begin to produce honey (their food supply) and lay eggs for new bees, they will defend their home. When they believe that either their food supply is threatened or someone will kill their young, they will defend their home by stinging. In many cases, this may lead to hundreds of stings. Bees do not attack. They are only defending their home. Sometimes noises, such as pounding the ground, or tools such as lawnmowers or weed eaters, will send out vibrations that make the bees believe someone is entering the hive to destroy it. They will send out bees to the source of the noise to defend the hive.

Bee hives are dangerous and should be removed by a professional bee removal service. It should never be done by a civilian. The process requires the use of professional safety gear and clothing. It is the responsibility of the property owner where the bees are located to have them removed if needed. The city of Las Vegas does not remove bees on private property. The Nevada Pest Control Association keeps a list of licensed removal services that is available at 702-385-5853. Residents should not try to exterminate the bees themselves.  Most people do not have the necessary safety equipment to remove bees. Past attempts by people trying to exterminate bees themselves have led to serious injury and death in some cases in the United States. This is extremely dangerous and you are advised to leave this to a professional exterminator.

Here are some safety tips concerning bees:

IF YOU SEE BEES, LEAVE THEM ALONE.

Swarming bees will appear as a large group of bees (that look like a football or basketball) hanging on the side of a building, on a fence, on tree branches or street signs. They sometimes can be found on the ground. Leave them alone. If weather is good, they will usually fly away. When they do, all of the bees will leave together. If you have them exterminated, a number of the bees (stragglers) will remain in the area for a day or two and they will be irritable because they cannot find the rest of the swarm. In most cases the bees will fly away to their destination within a day or two. If they remain for more than three days, you should then consider having them removed by a professional bee removal service.

IN CASE YOU HAVE AN ENCOUNTER WITH BEES . . .

You should run from the bees as quickly as you can. Bees are slow flyers and cannot keep up. Try to cover your face with either your hands or a shirt while running (bees will attack the eyes-nose-mouth).

Seek shelter in a building or vehicle. Do not jump into a pool or lake, the bees will attack when you come up for air.

The bees will continue to be agitated after the attack by loud or humming noises, such as barking dogs, lawnmowers, weed eaters, flashing lights, etc. Try to keep the area as quiet and calm as possible.

If it appears that a person is being attacked or other people are in imminent danger because of the attack, you should call 9-1-1 immediately.

If someone is stung by a bee and becomes dizzy, nauseated or has difficulty breathing, an allergic reaction to the sting might be occurring. This is a serious medical emergency and 9-1-1 should be called immediately.

If you are stung, remove the stinger by scraping it out and washing the area with soap and water and applying a cold pack to the sting site.

If you are stung more than 10 times, you should go a quick care center or contact your personal physician and be checked out. Reaction to bee venom takes several hours, which may cause you to feel sick later. People with an allergic reaction should call 9-1-1 and seek immediate medical attention.

A number of encounters with bees have occurred in the past to hikers on Lone Mountain.   Hikers should be aware and expect bees on the mountain while hiking.  Most of the time they are in small caves, holes or inside dead desert plants.  If bees start to attack while hiking, turn around and go back in the direction where you came from. You probably were entering their defense area.  Cover your head and run or walk quickly from the area.  Bees are slow flyers and will not be able to keep up with you. Get at least a quarter mile from them before you stop.  Do not wave your hands or swat at them, as this will keep the encounter going.

The term “killer bees” is typically misused in reference to bees and should not be used unless the bees have been properly recognized as such. That is done by the Nevada Department of Agriculture, which has to conduct a certain test for identification purposes. The test can take several days.

MORE INFORMATION ABOUT BEES AND SAFETY TIPS ARE AVAILABLE BY CALLING 702-229-2000 (two-minute recording of safety information about bees).  DO NOT CALL 9-1-1 TO REPORT SWARMS OF BEES UNLESS SOMEONE IS BEING ATTACKED.
