Carpenter bees, although not dangerous to humans, can be very detrimental to wood. These insects are known for drilling into wooden structures, causing damage that can compromise the structure’s integrity. Understanding how to manage and prevent carpenter bees will safeguard the longevity of wooden structures


Carpenter Bee Lifecycle and Behaviors

Carpenter bees are larger, round bees with shiny abdomens. They rarely attack unless provoked but can be quite a nuisance. They look like bumblebees but do not have bands. During the summer, the female bees drill tunnels in wood to create a nest to lay their eggs. They usually spend winters hibernating in the tunnels.

When picking out a nesting site, they prefer a weathered wood. They often reuse the same nesting site throughout generations. Usually, adult carpenter bees are more active in mid to late summer since it is mating season. 


Signs of Carpenter Bee Activity

When working on your projects, pay attention to the following signs to know if the jobsite has a carpenter bee problem. 

  1. The most noticeable indicators are the visible signs of damage. These could include perfectly rounded holes in wood surfaces, sawdust-like piles, and yellowish stains near entrances.
     
  2. Other signs to pay attention to are ones you can hear. Pay attention to buzzing and chewing noises. 


Prevention Methods

Taking preventative measures is an effective strategy to avert a carpenter bee infestation. There are several different approaches you could take to this. First, examine and seal any cracks or holes in wooden structures to eliminate nesting sites. Either wood putty or caulk will work. Applying a fresh coat of paint or staining wood surfaces can act as a deterrent. Using a barrier like installing metal coverings or fine netting over potential nesting areas can also help. Using wood alternatives will also prevent carpenter bees. Continue to inspect wooden structures to allow for early intervention regularly.


Control Methods

If a carpenter bee infestation has already begun, there are a few different measures you can take to protect your client’s wooden structures. Advion and PT Fedona insecticides are efficient products for removing carpenter bees. Additionally, applying insecticidal dust directly into the holes can eliminate bees inside tunnels. 

For a more natural deterrent, try hanging decoy nests like paper bags. The bees mistake them for wasps' nests and avoid the area. Additionally, investing in carpenter bee traps can also go a long way for your customers.


Personal Protective Equipment

Although carpenter bees are not usually dangerous to humans, it is key to wear proper protective clothing when taking control measures to avoid getting stung. When threatened, they will attack. Wearing shirts with long sleeves or protective eyewear will prevent injury. 


Long Term Monitoring

Ensure you constantly monitor and check in on your client’s wooden structures, particularly in spring and summer when the bees are done hibernating and become active again. 

Pay special attention to more worn wood and areas like decks. Installing traps can aid in long-term prevention. Keeping a record of where and when bees appear can help track patterns and areas that are more vulnerable. Doing your best to reinforce preventive measures like treating wood surfaces and replacing damaged wood can reduce the likelihood of future infestations. These extra steps will not only keep your client’s properties free from carpenter bees but also set you apart from your competition. 

By staying vigilant and quickly addressing issues, you can effectively manage carpenter bees and keep your customers’ wood structures safe.
