Bee and Honeycomb Removal Specialists
Q: If I leave the bees alone will they just go away?
A: Not before they do significant damage. Once bees live in a wall or in an attic they will usually stay. The bees will make a honeycomb in the wall and up in the attic. Honeycombs will not go away on their own. Once the bees are removed, the honeycomb needs to be removed as well.
Q: There is a honey bee hive in my attic. How quickly will the honey bee hive make a honey comb?
A: A honey bee hive will make a honeycomb fairly quickly. The rate at which the honeycomb is made depends on the size of the bee hive and if they are European honey bees or Africanized honey bees. Africanized honey bees were genetically created for their fast production of honey.
Q: Why is bee removal important if they are in my attic?
A: The honey from bees will do significant damage in your attic and can be very expensive if it is not removed. The longer the bees have to live in the attic the more time they have to create a honeycomb. Honeycombs attract roaches and rats and will ruin drywall. Honey bee removal is essential to prevent costly damage in the attic and prevent pests from invading the home.
Q: Is honey bee removal necessary?
A: Honey bees are an essential part of the ecosystem. However, when a honey bee hive is created in a wall or in an attic the honey bees become a danger to anyone living in that home. Allergic reactions are common and could result in a hospital visit. There is no physical characteristic to tell apart the European honey bee from the dangerous Africanized killer bee. An attack from an Africanized honey bee colony could result in the death of a pet or human. The honey needs to be removed from the wall as well to prevent pests and damage to the home.
