The tradition of painting a porch ceiling blue originated in the south in the early 1800s and was most commonly seen in Georgia and South Carolina.

The shade of blue used is often referred to as “haint” blue. Haint blue encompasses many blue-green shades. The word haint is pronounced “haunt” and refers to an evil spirit. According to Gullah folklore, the blue would ward off any evil spirits and prevent them from entering the home. The color blue was used because haints could supposedly not cross water. 

Insect Repelling

Let’s talk about why blue paint might repel insects. There are a couple of theories. 

In the past, the type of paint that would have been used to paint the porch ceiling contained lime. It was known as milk paint. Lime is a natural insecticide so it’s possible this is the reason, rather than the blue paint color, that bugs would avoid the ceiling. 

However, some people believe the reason spiders, bees, and wasps will avoid making a nest on their porch is because the blue paint looks like the sky and fools the bugs. While there’s no scientific evidence to back this up, there have been some personal testimonies to this. Some people say they saw much fewer cobwebs, spiders, and wasps nests after painting their own porch ceiling blue. 

Longer Days

Painting the ceiling blue doesn’t just fool the bugs. It also fools us humans. Painting the ceiling blue is said to give the impression of a longer day. If you looked up at the end of the day while you were sitting on the porch, the blue would look like the daytime sky, thus making you think the day was lasting longer. 

What Are The Best Paint Colors For Porch Ceilings?

So, we’ve discussed that many people in the south paint their porch ceiling blue, but is blue the best paint color for porch ceilings?

The most popular paint colors for porch ceilings are in fact haint blues. Regardless of the origin of painting a porch ceiling blue, blue is a comforting and welcoming color so it very well might be the best option. It can create a relaxing, inviting environment and is aesthetically pleasing to the eye.

Colors Other Than Blue

Just because haint blues are popular, it doesn’t mean you have to paint your porch blue. Any exterior paint will work, and you don’t have to follow the norm. Go bold with oranges and yellows! Though we can’t promise they’ll repel bugs, they’ll definitely bring some sunshine to your front porch. If bright colors aren’t your thing, choose darker colors instead.

How Do You Get Rid Of Bugs Around Your Porch Lights?

It can be frustrating when bugs are swarming your porch light. You try to sneak in your front door quickly, but there always seems to be at least one pesky insect that follows you in. There are a few measures you can take to get rid of the bugs around your porch light so that you no longer have to worry about fighting off the swarm as you enter your home or enjoy an evening on your porch.

Bug Zapper

You can keep a bug zapper nearby. Bugs are attracted to UV lights the most, so they definitely won’t be able to resist heading towards a bug zapper instead of your regular porch light. They are one of the most effective ways of getting rid of bugs.

Turn The Light Off More

Try not to leave your porch light on as long. The longer you leave the light on, the more time the bugs have to accumulate. If you have more than one porch light, turn off any unnecessary ones. 

Screen Your Porch

Screening your porch might be a more expensive venture, but might be worth considering if you live in an area where the bugs are unmanageable. If you choose a screen with a small enough mesh, you’ll have a bug-free porch light in no time.

Use A Bug Deterrent

Place some citronella candles around your porch to deter bugs. You can also try using essential oils. They might not prevent every bug from paying a visit, but it should at least help reduce the numbers.

Is There A Light That Doesn’t Attract Bugs?

So we gave you some ways you can get rid of bugs around your porch light, but is there a light that doesn’t attract bugs at all? You’ll be glad to know that, fortunately, there is!

We mentioned earlier that a bug’s favorite light is UV light. This is why they are so drawn to the bug zapper. Any light that emits little to no UV light will attract bugs less. Also, bugs can’t see every color of light, so using a color that bugs can’t see is the best way to not attract them. Not surprisingly, light manufacturers started producing bulbs in these colors, so they are readily available.  

Bugs cannot see a red light at all, but a red bulb might not be a very good option for your porch. The next best color to use is yellow. You should replace your porch lights with yellow bulbs. The best yellow bulb to use is a compact fluorescent light as it is more energy-efficient and gives off less heat. Sodium vapor and halogen bulbs will also work.
