How Do Moths Reproduce – What You Can Do To Prevent It

The presence of one or two moths inside your home isn’t always a huge concern. Although the vast majority of adult moths are harmless, their newly hatched larvae are destructive. But how do moths reproduce?

Here’s vital information on moths and ways of preventing moth problem in your home.

How Do Female Moths Reproduce? About Moths

Moths are tiny insects that inhabit fields and homes. There are about 160,000 moth species, but only a few species venture into people’s houses. Other species are relatively harmelss.

Moths are in the order Lepidoptera, a group of insects related to butterflies. Unlike butterflies, moths have hairy antennas that lack a ball end. But like butterflies, moths need to mate to produce offspring.

The Sexual Reproduction

While butterflies find mates by sight, most moths attract mates by sense of smell. The female moth produces pheromones, which are chemical signals that attract the male moth.

When the male discovers the pheromones released, the males will fly toward it and ultimately locates the source of the scent.

Males can release the same chemicals as well. Pheromones are chemicals that some male moths and butterflies produce to attract females of the same species. These pheromones are located on the moth’s wings in the form of scales.

The Mating Process

The male moth mounts the female to mate by attaching themselves at their abdomens. This begins the mating process. Males hold on to the female with their “claspers,” which are short, hand-like appendages on their anus.

Next, males pass a sac, known as the “spermatophore,” through their penis – this comprises not only sperm but additional nutrients that support growing moth larvae.

The female then extends her proboscis, which is a long, tube-like structure, and inserts it into the male’s Aedeagus. The Aedeagus is an opening at the base of the abdomen through which the sperm is released.

Once the female has inserted her proboscis, the female withdraws it and bends it backwards so that it comes into contact with the male’s genital opening. This process allows the females to collect sperm from the males. Female moths can mate with several males before it lays eggs.

The female stores the sperm in her body until she is ready to reproduce. When the female lays her eggs, she uses the stored sperm to fertilize them. A variety of moths lay eggs in various locations, at varying rates.

Egg Laying and Life Cycle of Moths

Most moth species go through four stages in their life cycle: egg, larva, pupa, and adult. The first stage is the egg. Moth eggs are usually laid on the leaves of plants, and they come in a variety of shapes and sizes depending on the species of moth.

Once the eggs hatch, the caterpillars, emerge and begin feeding on the host plant. This is the larval stage of the life cycle. Moth caterpillars feed on plants and spend the majority of their time eating. They can go through a lot of food source in a short period of time.

Depending on the species, moth caterpillars can either spin cocoons around themselves or burrow into the ground until the caterpillars turn into pupae.

Most caterpillars choose to hide by disguising themselves as bird poo, a twig or blending their colours into their surroundings. This is because they are relatively immobile compared to adult butterflies, which can fly away quickly to escape predators.

The majority of caterpillars become moths, and not by a small margin: 95 percent will hatch into moths. Once they emerge as adults, moths mate and lay eggs to begin the cycle anew. This is referred to as complete metamorphosis. Although there is some variation in the life cycle of moths, the overall process is similar for most species.

Are Moths Pests?

Moths become pests when they invade your home and wreak havoc. These pesky insects can destroy your fabric, carpet, and furniture. Once in your home, moths look for dark, secluded corners where they deposit eggs.

Most of the destruction is usually caused by the moth larvae (caterpillar). They eat almost everything in your home, be it clothes or treasured possessions.

How Moths Enter Your Home

Like other rodents/insects, moths enter your house through torn screens, window cracks, or door frames. Some species may gain entry into your home by hiding in clothes, furniture, or other goods you buy from shops.

You might find moth eggs in common household foods like cereal, dried fruit, and flour.

Home lighting also attracts moths. According to scientists, these insects are positively phototactic. You’ll notice moths gathering around indoor and outdoor lighting at nighttime.

Most Common Moth Pests

Only a few moth species infest your home. But many species have different lifespans, characters, and appearances; although they may share a similar reproductive cycle.

Clothes Moths

Two types of clothes moths inhabit North American homes. These species are the case-making clothes moth and the webbing clothes moth.

Webbing Clothes Moths

Webbing clothes moths are tiny moths that live in moist, low-humid environs. Adult clothes moths are approximately 0.24-0.28 inches in length. Unlike other moths, they prefer dark areas. You’ll find them hiding in closets, wardrobes, attics, and handmade rugs.

You may also wonder how many eggs do moths lay and how long it takes moth eggs to hatch. Well, females lay up to 100 eggs in hidden materials such as folds of furnishings.

The eggs have a sticky substance that makes them stick firmly to fabrics. In the summer, the eggs hatch in about 4-10 days, while in the winter, the hatching period extends to 3 weeks.

The cream-colored larvae are about 0.4 inches long and mature into adults in approximately six weeks. The larvae are notorious for feeding on natural fibers and clothing. They eat dirty clothing that’s soaked with sweat. Once the larvae reach adulthood, they cease eating clothes.

Case-making Clothes Moths

Case-making clothes moths are of similar size to the webbing moths. Unlike the webbing moth, this species is darker and has three spots on each wing. These moths spend most of their time hidden in dark areas.

Homeowners often ask, how do moths reproduce? Reproduction starts when moths mate, then females lay fertilized eggs. The eggs hatch into larvae within a week. Immediately the larvae emerge, they start feeding on fabric. They feed for about three months, and during this period, they molt 5-11 times.

Brown House Moths

These are large, less destructive adult moths. Adults can grow up to 18mm in length, while their larvae are about 20mm long. These moths are brown and have three or four dark spots on the wings.

Adults are scavengers that feed on dead insects, while larvae prefer feeding on animal textiles like leather, feathers, and wool.

The larvae will occasionally eat book bindings, grains, paper seeds, dried plant matter, corks, and food products.

Brown house moths only have a single generation per year. This translates to a low population growth rate compared to other moths.

White-Shouldered House Moth

This moth’s name originates from the white-shouldered pattern on its forewings. Its wingspan ranges from 15 to 17 millimeters, making it one of the tiniest moths in North America.

It’s an outdoor moth that occasionally inhabits isolated buildings. The larvae are yellowish-green with dark spots. They scavenge a wide range of foods, including lichens and fungi.

The white-shouldered house moths are less destructive since they spend minimal time indoors.

Gypsy Moth

The gypsy moth was brought to America in the 1860s by a man named EA Douglas who hoped to start a silk industry in the US. However, the gypsy caterpillars quickly began to wreak havoc on American forests, devouring the leaves of oak, maple, and other trees.

In an effort to control the gypsy moth population, the US government has released several biological control agents, including a virus that kills gypsy caterpillars. While these efforts have had some success, the gypsy moth continues to be a serious problem in many parts of the country.

Winter Moth

The winter moth is a type of moth that is common in winter. This moth gets its name from the fact that it is often seen in winter, when most other moths are not active. The winter moth is a small moth, with a wingspan of only about 1/2 inch.

It is brown or gray in color, and has a long, thin body. The winter moth is attracted to light, and can often be seen flying around porch lights or streetlights in winter.

How Do Moths Reproduce? Identifying Moth Infestation

The obvious sign of moth infestation in your home is damage to your clothes, carpet, and textiles. Start by inspecting clothes stored in dark closets or wardrobes. If you notice any holes in your clothes, know the primary culprits are moths.

How to Get Rid of Moth Larvae

Killing moths won’t eradicate them from your home. Even if the moths are gone, the eggs they leave behind will develop into larvae and finally adults. You have to answer the question, how do moths reproduce before seeking a long-lasting solution. Here’s how to get rid of moths’ eggs, larvae, and pupa.

Start by clearing out the affected shelves, wardrobes, closets, and cupboards. It’s advisable to regularly empty your vacuum to get rid of the eggs and larvae for good.

Wash infected containers and surfaces with vinegar. This involves cleaning furniture, wardrobes, old bags, cases, drawers, and anything that might shelter moth larvae.

Below are effective ways of removing adult moths from your home.

Set Up Moth Traps

You can set up a sticky trap and cover it with pheromones. The pheromones will attract moths, and the sticky surface will trap them until they die. You can use a combo of flypaper and fish oil.

Fill Your Home with Scents

Scents from cedar, rosemary, lavender, thyme, and bay leaves repel moths.

Ventilate You Home

Moths are unlikely to nest in a place with too much sun and air.

Call a Pest Control Service

Getting rid of moth infestation isn’t always straightforward. If you’re overwhelmed, you can call an exterminator to assess and find solutions.

How Do Moths Reproduce? Bottomline

Moths aren’t harmful, but their larvae are very destructive. Luckily, the above methods can help you get rid of your moth problems and their larvae easily.
