Remove A Carpenter Bee Nest From Your A/C Condenser Unit's Exterior Before Cleaning The Unit

Blog

If a carpenter bee nest is attached to your outdoor air conditioner's condenser unit, removing it will prevent blockages inside of the unit, which could interrupt airflow in your home. The following steps describe how to safely destroy bees and remove the hive before cleaning the condenser unit. Maintain the unit to prevent pests from building a nest on the unit's exterior again.

Materials You Will Need

  • gloves
  • large net or fabric mesh
  • drop light
  • powder pesticide
  • spray pesticide
  • rake
  • broom
  • cordless drill
  • screwdriver
  • waterproof cloth
  • hose
  • coil cleaning agent
  • wire brush
  • detergent
  • cloths
  • sponge
  • shop vacuum cleaner
  • tarp

Eliminate The Carpenter Bees And Hive

Administer pesticide to the nest of carpenter bees when it is dark outside to reduce the possibility of being stung by bees. Most bees will be inside of the nest and will not be active. Check to make sure that the power to the air conditioning unit has been turned off. Cover your hands with thick gloves and cover your head and face with a large net or a piece of fabric mesh just in case there are a couple of bees that are lingering near the nest's opening when you go outdoors.

Shine a drop light toward the condenser unit's exterior to help you locate the opening to the nest. Administer power or liquid pesticide. Wait until the following day to remove the hive from the condenser unit since it may take a while for the carpenter bees to die. The following day, go outdoors and use a rake or broom to loosen the hive from the condenser unit's cover. Dispose of the hive.

Clean The Unit's Cover And Interior And Maintain The Unit

Use a drill or a screwdriver to remove hardware pieces that are attached to the unit's cover. Lift the cover from the unit and lay it on a waterproof cloth. Use a hose to spray both sides of the cover. Remove loose debris from the unit's interior components by briefly spraying them with a stream of water. Remove surface stains from metal pieces by administering a coil cleaning agent to them.

Use a wire brush to help you loosen stubborn residue. Wipe both sides of the unit's cover with a soapy cloth. Remove cleaning agents with a damp sponge. Dry surfaces with another cloth. If debris is wedged between small components inside of the unit, use a vacuum cleaner hose to loosen and collect them. 

Protect the unit from bees by occasionally rinsing off its surface with water during the months that you use air conditioning in your home and by covering the unit with a tarp during the winter or extended cool periods that you won't be turning on the air conditioning in your residence. Spray your property with pesticide to further deter carpenter bees. To learn more, contact an AC services company.
