Can Bees Eat Through Caulk?

If you have bees in your house, you might be looking for ways to get rid of them. One way to do this is by sealing cracks and gaps that the bees use to enter and exit the home. 

Bees can fly through this gap and enter your house through these cracks! If your house has caulking around windows or other openings, it’s important to make sure that the caulk doesn’t allow any space between it and the wood of your home.

In this blog post, we’re going to explore the possibilities of bees eating through caulk. Let’s get started!

Can bees eat through caulk?

Yes, bees can eat through caulking. But to be honest, it’s not a good idea for you to let them. Bees will often chew and pierce their way into walls and other surfaces in order to create nests for their hives. This is especially true during the winter when they aren’t getting enough pollen and nectar from flowers outside. If you find yourself with a bee infestation, contact a professional pest control company immediately to remove the hive safely.

Bees are also attracted to the smell of plastic. This is why they like to chew on caulk and other plastics! Bees also have an affinity for wood, which makes sense considering that wood comes from trees and plants, just like bees do as a beekeeper. Sometimes you’ll have to break open walls and floorboards to get at the hive. But never use caulking as part of this process because it’s incredibly harmful to bees.

What kind of bees like eating caulk?

Caulk, a type of plastic, is made from petroleum byproducts. Bees like to eat plastic because it is sweet and smells like a honeycomb. They also like the plastic color and how smooth it feels in their mouths (you can try this yourself with your finger). As you might guess, bees prefer easy foods to chew on. In addition to having an affinity for caulking products, bees also enjoy chewing on wood and other non-plastic materials!

Bees can chew through caulk quickly and easily, but this does not mean your home will be overrun with bees. Caulk is just one of the many things that attract these insects. Other items include wood-based products like paper towels or cardboard boxes, flowers that provide nectar to eat and make honey, and sticky substances such as syrup or honey.

How much caulk is needed to fill a crack outside my house?

It depends on the size of the crack. A tube of caulk should be enough for most damages, but if it’s larger than two inches in width, you may need more. However, if you’re using caulk to seal a crack and want it to last longer than just one season (or even longer), it makes sense that you’ll need more to cover a greater surface area. 

If you’re unsure how much caulking material would work best for your project, just ask at your local hardware store or home improvement store how much would be needed for a job like yours.

What other materials can bees eat through?

Most people know that bees can and have eaten through the caulking around their windows, but did you know they can also eat through wood and plastic? Bees are even known to chew on rubber, metal, and concrete. They don’t seem to be picky when it comes to making a home!

If your home is made with wood or plastic siding, you might want to consider moving your hives away from any windows or doors. Bees will likely find their way into your house if they smell food inside or see enough light through the cracks. If an opening in your walls is big enough for a bee to fit through (even if it’s only about the width of his body), he will find that entrance and use it as an exit. 

Once inside your walls, bees will begin chewing on whatever material they find until they reach something sweet like sugar syrup or honeycomb—or even some watery syrup from one of those hummingbird feeders!

Can bees fit through caulk cracks?

So, can bees fit through caulking cracks? The answer to this question is yes and no. Bees are small enough to fit through caulk cracks, but they will not be able to fly into or out of the crack. 

If you have a crack in your caulking that has been there for years, then it is possible that bees could fit inside and help themselves to whatever food source may be available within your home. It is also possible that these same bees could use that crack as an entranceway into your home if the other access points were blocked by something like a window screen or door frame.

What to do when bees are eating through the caulk

If you see bees in your home or hear buzzing, it’s essential to contact a pest control professional immediately. You can sometimes remove the bees without having to pay for expensive repairs.

It is possible that this is not a bee problem but rather an ant problem. Ants have also attracted to moisture and humidity like bees are. So if there are ants in your home or near where you heard the buzzing sound, it may just be that they were attracted by the moisture and not from any damage done by bees eating through the caulk around windowsills or doors.

So what can be done about these pesky pests? Some people simply choose to replace the damaged caulk with new material, but this often does not prevent future damage. Another option is using some form of physical barrier like oil-based paint that will seal off any openings where bees may enter.


Hopefully, you can now answer the question of whether or not bees can eat through caulk! Bees are very good at getting into things that you should seal off. They’re also very good at eating through them.

So if you have an area in your home where you need to protect against pests, it is best to use a non-toxic pesticide. If bees around your home are trying to get in through cracks or crevices in between wood floors or walls, then this may be a sign that there’s something inside that needs cleaning up.
