Have you found moths in house and now wondering what you should know about these pests? Then this article is for you.

Moths are members of the order Lepidoptera and belong to the group of paraphyletic insects. Look wise, they are very attractive and look like butterflies. More than 160,000 different species of moths exist and they can be found all around the globe.

These species are differentiated by size, shape and colour. They keep flying from the flowers of one plant to another and play an essential role in pollination. They are also an easy source of food for birds and bats.

In this blog post, we will share 25 interesting facts about the moths in your house.

1.    Types of Moths

There are several moth species, but in this blog, we’ll discuss the two most common types; macro moths and micromoths.


As it is clear by the name, in this class of moths, larger moths are categorised as giant silk moths, tiger moths, and the ever-popular Luna moth. Their size is extraordinarily large, and their appearance is bright-coloured wings.


This class of moths consists of small-sized moths present in residential areas and can damage household things. They are tine size insects, and their wings are drab-coloured. Clothes moths and pantry moths are an example of micromoths.

2.    The Moth Life Cycle

Moths pass through four Lebenszyklus stages to reach the adult stage. The first stage starts when the female legt Eier. After egg hatching, the larva comes out and spends a specific amount of time reaching the next stage, the pupa.

After completing specific food consumption and digestion cycles, they mature enough to be called adults.

At each stage, their body size varies, and it also depends upon the type of species and the surrounding environment.

Surprisingly, moths do not eat food at the adult stage because moths do not have a mouth. On the other hand, larvae and caterpillars eat flowers and plant material to grow and stay alive.

3.    A male moth can sniff off a female moth from 7 miles

Male moths’ sense of sniffing is incredible; they can sniff the smell of female moths from 7 miles. Females emit pheromones that attract male moths. This miraculous sense of moths helps them trace the location easily because they are nocturnal pests. This trait also helps researchers to locate the exact location of moths’ moment.

4.    Moths don’t have noses

If you are shocked after knowing that moths also don’t have noses, then it’s the truth. Moths don’t have traditional noses like a few insect species. They have developed special organs in the form of antennas that they use to sniff the smell and detect other environmental cues. The sensitivity of these antennas is incredibly strong and can detect even the faintest scents.

5.    Some moths can survive underwater

Like other insect species, a few moth species are also developing their living style according to the changes in the environment. For example, caddisfly have adapted to live in aquatic environments. They have developed specialized gills which assist them in extracting oxygen from the body and surviving underwater. These moths are a vital source of food for small sea species like fish.

6.    How long do moths live?

The life span of moths can vary depending on the moth species and environmental conditions. For instance, the Luna moth can only live for a few days. On the hand, the Polyphemus moth can live up to 30 days. It is a shocking fact about moths that the adult stage of moths is the shortest stage of their life span, and the primary purpose of adult moths is to lay eggs and reproduce for the next generation.

7.    What does a moth eat?

This trait is not solely present in moths; several other adult insects do not have mouths.
