Most people are at least aware that carpenter bees can be a nuisance to your home because they drill holes in wood such as siding or porches. That being said, when you really start to think about it, how do carpenter bees actually drill holes into wood? How do these relatively small insects actually have the strength to drill holes into wood to create their nests? Well keep on reading below and you’ll find out!
How Do Carpenter Bees Drill Holes In Wood?
Carpenter bees are not the most attractive insects in the world. In fact, you might even call them scary. They’re big and black with a red spot on their thorax- which is located between their head and abdomen. And they like to chew holes into wood that can cause extensive damage if left untreated.
But when it comes to drilling holes, carpenter bees have an amazing talent: they don’t use tools! Carpenter bees drill using their mandibles (which are located near the mouth). They use these mandibles to slowly and steadily rip and tear tiny layers of wood away in a circular pattern until they’ve formed a hole big enough for their nest.
This is quite a slow process because it’s estimated that carpenter bees can only drill about 1 inch every few days. This means the entire nest can take weeks to finally complete.
Why Do Carpenter Bees Drill Holes?
Carpenter bees are not interested in eating wood; there is no nutritional value to them whatsoever. They don’t eat (or suck) sap like other carpenter insects either, like termites or carpenter ants. The drill holes for one purpose: to create a nest and lay their eggs! Carpenter bees use their strong mandibles to chew through the wood so that they can create a spacious chamber for their eggs and to provide ventilation while keeping them safe from any predators.
Carpenter bees drill holes into wood that is found on outside structures, like decks or eaves or even sheds and gazebos. If you see these large holes in your wooden structures, it could be an indicator of a larger problem. Carpenter bee holes can be a signal that your house is under attack from another carpenter bee species, the wood-boring bees. These female bees carve out tunnels in which to lay their eggs; they are especially active between February to May and again sometime during August to September.
Are the Carpenter Bees Eating the Wood?
No. Carpenter bees do not eat wood like termites or carpenter ants, nor do they sip the nutritious sap like other wood-boring insects. They actually create holes for a nesting spot.
Is it Males or Females Drilling/Cutting the Holes?
The females drill the holes while the males defend the colony. It’s easy to tell the difference between them because males lack a stinger. They like to hover around drilling areas and make loud noises while trying to get the females’ attention!
Do Carpenter Bees Damage Homes?
Yes, carpenter bees can cause significant damage to your house’s wooden structures. However, they rarely sting humans. This can compromise the structural integrity of your home, and if the infestation is not addressed, it could lead to a large-scale problem.
How to Identify a Carpenter Bee Infestation?
The easiest way to identify a carpenter bee infestation is by looking for large, cylindrical holes in wood. The female drills these holes using her extremely powerful legs and jaws; she can drill into one area several times before moving on to the next section of wood.
How can you stop carpenter bees from drilling or extending their holes?
There is no surefire way to get rid of carpenter bees; they can be extremely persistent and hard to deter. The best thing you can do is address the source of the problem. If the bees are coming from your wood structures, you can repaint or caulk or seal any holes that they might be using to enter and exit their nests.
