Love Bugs: What are They and How to Get Rid of Them? (2024)

Love bugs, also known as the honeymoon or double-headed fly, are a species of march flies that are commonly found in parts of Central America and the southeastern United States.

Despite their seemingly affectionate name, these insects can become quite a nuisance, particularly during their mating seasons which occur twice a year. They are known for their unique mating behavior, where the male and female remain attached for several days.

Contrary to popular belief, love bugs do not bite or sting, making them harmless to humans. However, their sheer numbers, especially during their mating periods, can cause inconveniences.

They often swarm around highways, resulting in visibility issues for drivers and potential damage to vehicles due to their acidic body chemistry.

In this article, I’ll go over everything you need to know about love bugs, and also discuss their origin, and how to get rid of them.

What are Love Bugs?

Love bugs, scientifically known as Plecia nearctica, are a species of fly that are quite common in parts of the United States, particularly in the southern regions. These small, red and black insects are often seen in large swarms, especially during their mating seasons in spring and late summer.

The name “love bug” is derived from their unique mating habits. After mating, the male and female remain attached to each other, flying in tandem for several days. This distinctive behavior, coupled with their striking red and black coloration, makes them easily recognizable and has earned them their romantic nickname.

Despite their endearing name, love bugs can be quite a nuisance. They are attracted to heat and the exhaust fumes of cars, often resulting in large numbers of these insects splattering on windshields and car grills.

Besides being a driving hazard, the acidic body fluids of love bugs can lead to paint damage if not removed promptly.

Lifecycle of a Love Bug

The lifecycle of a love bug consists of four distinct stages: egg, larva, pupa, and adult.

The process begins when female lovebugs lays their eggs in decaying organic material, such as grass clippings or leaves in flower beds. This provides a nutrient-rich environment for the eggs to develop. The number of eggs laid can vary, but it’s usually in the range of 100 to 350.

The eggs then hatch into lovebug larvae, which are small, worm-like creatures. The larvae stage is the longest in the love bug’s lifecycle, lasting up to nine months. During this time, the larvae feed on the decaying organic material around them, contributing to the decomposition process.

After the larvae have grown and developed, they transition into the pupa stage. This is a period of intense transformation where the love bug develops its adult features. The pupa stage lasts for about a week.

Finally, the love bug emerges as a fully formed adult. Adult love bugs are known for their unique mating behavior, where the male and female remain attached for several days. This is where the “love bug” moniker comes from. Love bug adults live for only a few days, during which they mate and the cycle begins anew.

What Do Love Bugs Look Like?

Love bugs are a species of fly that is easily recognizable due to their distinctive physical appearance. They are small, usually measuring about a quarter of an inch in length. Their bodies are black, but what makes them stand out is their red thorax. This stark contrast between the black and red is one of the primary identifying features of love bugs.

Their wings are translucent and are roughly the same length as their bodies. When at rest, their wings lay flat over their bodies. They have six legs, which are also black, and their antennae are short and stubby.

As mentioned previously, an interesting characteristic of love bugs is that they are often seen in pairs, with the smaller male lovebugs attached to the larger females. This is why they are commonly referred to as “love bugs”. This unique behavior of love bugs is a result of their mating process, which is another distinguishing feature of these insects.

While love bugs may not be harmful to humans, their large swarms can be a nuisance, especially during their peak mating seasons in the spring and late summer. Understanding what love bugs look like can be helpful in identifying and managing their presence.

How and When Did Love Bugs Get to the United States?

Love bugs are not native to the United States. They are believed to have made their way from Central America, specifically from Guatemala, in the early 20th century. The first recorded sighting of these insects in the United States was in Texas in the 1920s.

The love bugs are thought to have migrated northwards, hitchhiking on plants and vehicles, or carried by the wind. Over the decades, their population has spread across the southeastern states, including Louisiana, Georgia, Alabama, South Carolina, and Florida.

Florida, in particular, has seen a significant increase in lovebug population. They were first reported in the state in the 1940s and have since become a common sight, especially during their peak mating seasons in May and September.

Contrary to popular belief, love bugs were not introduced to the United States as a form of pest control. This myth likely originated due to their close resemblance to a species of fly that was indeed introduced for pest control purposes.

The spread of love bugs in the United States is primarily attributed to the absence of natural predators and favorable environmental conditions. Their larvae feed on decaying plant material, which is abundant in the humid, subtropical climates of the southeastern states.

This, coupled with the lack of predators, has allowed this pesky bug’s population to thrive and expand over the years.

Myths Surrounding Love Bugs: Are They a Product of an Experiment?

One of the myths surrounding love bugs is the notion that they are not a naturally occurring species, but the product of a science experiment gone awry. This rumor, as fascinating as it may be, is not grounded in fact.

The story goes that love bugs were genetically engineered by scientists at the University of Florida as a means of pest control. The intention was to create a species that would prey on mosquitoes and other harmful insects. However, the experiment supposedly backfired when the love bugs, having no natural predators, proliferated uncontrollably.

Despite the widespread belief in this narrative, there is no scientific evidence to support it. They are native to Central America, and their migration to the United States is a natural occurrence, not the result of a laboratory experiment.

Their rapid population growth in the United States is due to favorable environmental conditions and the absence of natural predators, not genetic engineering.

Where Do They Go?

Love bugs are not migratory insects and they generally stay within a certain radius of their birthplace.

After mating, female love bugs lay their eggs in decaying vegetation on the ground. This provides the larvae with a rich source of food when they hatch. The larvae then burrow into the ground and remain there until they mature into adults. This cycle of life means that love bugs are usually found in grassy and marshy areas, and are particularly prevalent near bodies of water.

During their adult life, love bugs are often seen in large swarms, especially during their peak mating seasons in May and September. These swarms can be so dense that they cause visibility issues for drivers. It’s during these swarms that you may wonder where they all go.

In fact, their lifespan as adults is very short – only about three to four days. After mating, the females lay their eggs and then die, while the males die shortly after mating. This means that the swarms of love bugs disappear almost as quickly as they appear, leaving behind only their eggs to continue the cycle of life.

What Attracts Love Bugs?

Love bugs are attracted to a variety of things. Understanding what draws these insects can help devise strategies for pest control.

First of all, love bugs are attracted to heat and vibrations. These insects are particularly active during the warmest parts of the day, and they are often seen swarming around vehicles and machinery. The heat emitted by these machines, along with the vibrations they produce, seem to be a magnet for love bugs.

Next, love bugs are attracted to certain smells. Specifically, they are drawn to the odors produced by decaying plant material. This is because love bugs feed on nectar and the decaying matter of plants. Therefore, if your garden has a lot of decomposing organic matter, it may attract love bugs.

Plus, love bugs are attracted to light colors and reflective surfaces. This is why they often swarm around vehicles and buildings that are light in color or have reflective surfaces. In addition, love bugs are also drawn to freshly painted surfaces, probably because of the solvents used in the paint.

Potential Damage Caused By Love Bugs

Despite their romantic moniker, love bugs can cause a fair amount of damage if not properly managed. While they are not harmful to humans and don’t bite or sting, their sheer numbers during peak seasons can become quite a nuisance.

One of the most significant issues with love bugs is their fondness for highways. Attracted by heat and vehicle exhaust fumes, these insects often swarm in large numbers around roads, leading to them splattering on the windshields and hoods of vehicles. This isn’t just a minor annoyance; the acidity in a love bug’s body can damage car paint if not cleaned off promptly.

Plus, their corpses can clog up radiator vents, causing cars to overheat. The accumulation of love bug bodies on windshields can also hinder visibility, potentially leading to dangerous driving conditions.

Around the home, love bugs can also cause problems. They are attracted to light-colored surfaces and freshly painted homes, where they can leave unsightly stains. Plus, when they die in large numbers around residential areas, their decaying bodies can produce a foul smell.

While love bugs are not pests in the traditional sense, their seasonal invasions can cause significant inconvenience and potential damage.

How To Get Rid Of Love Bugs

Love bugs can be a nuisance, but fortunately, there are several effective methods to get rid of love bugs and prevent them from causing havoc:

Maintaining a Clean Environment

Love bugs are attracted to heat, decomposing plant debris, and the smell of fresh paint. Keeping your environment clean can significantly reduce the chances of a love bug infestation. Regularly dispose of organic waste and avoid leaving piles of grass clippings or leaves around your property.

Use Light Colored Traps

Love bugs are especially attracted to light colors. This is why you often find them swarming around light-colored surfaces, such as walls and vehicles. Because of this, one effective way to control the love bug population in your vicinity is to use light-colored traps.

These traps work by attracting love bugs to their light surface, then trapping them so they cannot escape. You can purchase ready-made light-colored traps from pest control stores, or you can make your own at home.

To make a simple light-colored trap, you will need a large piece of light-colored cardboard or plastic, some sticky substance like honey or glue, and a stand or support to hold the trap upright. Apply the sticky substance to one side of the cardboard or plastic, then set it up in an area where you’ve noticed a lot of love bug activity.

Remove Stagnant Water

Another effective method to control the population of love bugs is to remove stagnant water around your property. Love bugs lay their eggs in damp soil, and stagnant water provides the perfect environment for this process.

Love bugs are attracted to moisture and humidity. They often breed in areas where water is plentiful, such as marshy areas and poorly drained lawns. If you have a water feature in your garden or a birdbath, ensure to change the water regularly to discourage love bugs from laying their eggs.

If you have areas around your home where water tends to accumulate after a rainstorm, you might want to consider improving your drainage. This could involve grading your yard to encourage water flow away from your home, or installing a French drain or other drainage system.

Clean Up Yard Debris

You can also prevent a love bug infestation by cleaning up yard debris regularly. Yard debris such as fallen leaves, grass clippings, and rotting wood can provide an ideal breeding ground for love bugs.

These insects are attracted to decaying plant material, which they use as a food source and a place to lay their eggs. By removing these potential breeding sites, you can significantly reduce the number of love bugs in your yard.

Start by raking up leaves and grass clippings and disposing of them properly. If you have a compost pile, make sure it’s well-maintained and turned regularly to discourage love bugs from laying their eggs there.

Trim overgrown vegetation and remove any dead or decaying plants from your garden. These actions will not only help control love bugs but also improve the overall health and appearance of your yard.

Use an Insect Spray

Insect sprays are a common and effective method for controlling love bugs. These sprays are readily available in most supermarkets and home improvement stores. When choosing an insect spray, look for one that specifically mentions its effectiveness against love bugs on the label.

The best time to use insect spray is in the early morning or late evening when love bugs are most active. Spray the areas where you’ve noticed love bugs congregating, such as around lights, windows, doors, and plants. Make sure to also spray any areas where you suspect love bugs may be breeding, such as stagnant water or yard debris.

When using an insect spray, always follow the manufacturer’s instructions for safe and effective use. This usually involves wearing protective clothing, avoiding inhalation of the spray, and keeping children and pets away from the treated area until the spray has dried.

Use Fans To Deter

Fans can be a surprisingly effective method for deterring love bugs. These insects are notoriously poor flyers and a strong breeze can make it difficult for them to navigate. Setting up fans around your outdoor spaces, such as patios, porches, or pool areas, can create a wind barrier that love bugs find hard to penetrate.

The strategy is not just about making it physically challenging for the bugs. The constant airflow also disperses the scent that attracts love bugs. They are drawn to odors, especially those emanating from decaying plant matter. The fans help to dissipate these smells, making your space less attractive to them.

When using this method, remember to position your fans so that they blow away from your living areas and not towards them. This ensures that any love bugs that are already present are pushed away rather than being drawn in.

Vacuum To Physically Remove

One of the most straightforward and effective methods to get rid of love bugs is by physically removing them. This method is particularly useful when you have a large infestation in a specific area of your home or yard. A vacuum cleaner can be a powerful tool in your arsenal against these pests.

The process is simple: just use the vacuum cleaner to suck up the love bugs. You can use a standard vacuum cleaner for indoor infestations, but for outdoor infestations, consider using a shop vacuum. A shop vacuum is more robust and designed to handle larger debris, making it ideal for outdoor use.

It’s important to empty the vacuum bag immediately after use to prevent the love bugs from escaping. Dispose of the bag in a sealed trash can. If you’re using a bagless vacuum, empty the canister into a plastic bag, seal it tightly, and dispose of it in a trash can with a lid.

Use The ‘White Bowl’ Technique

Another effective method of controlling love bug populations is to use the ‘White Bowl’ technique. This simple yet ingenious method leverages the love bugs’ natural attraction to light colors, particularly white, to trap and eliminate them.

To use this technique, you’ll need a large white bowl, water, and a few drops of liquid dish soap. Fill the bowl with water and add the dish soap, stirring gently to mix. The soap reduces the surface tension of the water, making it difficult for the bugs to escape once they land.

Place the bowl in an area where you’ve noticed a high concentration of love bugs. The white color of the bowl attracts the bugs, and they will fly towards it, mistaking it for a large white flower. Once they land in the soapy water, they will be unable to fly away, effectively trapping them.

Installing Bug Lights

Bug lights can help reduce the attraction of love bugs to your home. These lights emit a yellow or orange glow that is less attractive to insects, including love bugs. Replace your outdoor white lights with bug lights to deter these pests.

Using Natural Repellents

Citrus-based products, like those made from orange or lemon, are known to be effective love bug repellents. You can spray these around your property to deter love bugs. Other natural repellents include certain plants like marigold and rosemary that can be planted around your home to keep love bugs at bay.

Professional Pest Control Services

If the love bug infestation becomes too much to handle, consider hiring professional pest control services. These experts have the knowledge and tools to effectively eliminate love bugs and can provide advice on how to prevent future infestations.

Remember, love bugs are more of a nuisance than a threat. While their presence can be overwhelming, these bugs are part of the ecosystem and play a role in decomposing plant material. Therefore, it’s essential to manage their population responsibly.

Frequently Asked Questions

Are Love Bugs Harmless?

Yes, love bugs are harmless to humans. They do not bite, sting, or transmit diseases. However, they can be a nuisance when they swarm in large numbers, and their acidic body chemistry can cause damage to car paint if not cleaned off promptly.

Do Love Bugs Really Mate For Life?

The term “love bug” comes from the insect’s mating habits. The male and female attach at the rear and remain together even while flying, feeding, and sometimes even after the female has laid her eggs. However, they do not mate for life. The males usually die after mating, while the females live long enough to lay their eggs and then die.

Why Are Love Bugs A Problem?

While love bugs themselves are not harmful, they can cause problems in large numbers. They are attracted to light-colored surfaces and the heat of car engines, leading to swarms of them on roads. These swarms can impair visibility for drivers, and the bugs can clog radiators, causing cars to overheat. Their bodies are also slightly acidic, which can damage car paint if not removed promptly.

How Can I Keep Love Bugs Away?

There are several methods to deter love bugs, as discussed in the previous sections of this article. These include using light-colored traps, removing stagnant water, cleaning up yard debris, using insect spray, making a DIY love bug repellent, using fans to deter them, vacuum cleaning to physically remove them, and using the ‘White Bowl’ technique.

What Do Love Bugs Eat?

Adult love bugs feed on the nectar of various plants, particularly sweet clover, goldenrod, and Brazilian pepper. The larvae, or immature love bugs, feed on decaying plant material in the landscape.

How Long Does Love Bug Season Last?

Love bugs are seasonal pests that are most prevalent during two specific periods each year. The first love bug mating season usually begins in late spring, around late April or early May, and lasts for about four weeks. The second season occurs in late summer, usually around late August or early September, and also lasts for approximately a month. However, the exact timing and duration of love bug seasons can vary based on geographical location and weather conditions.
