Moths are insects that can fly and they are close relatives of the butterflies. These insects are brown, grey, white, or black; unlike their colorful relatives. Moths are known to rest by keeping their wings in a flat position which makes them different from butterflies. While moths may seem to be tiny in size they can still successfully damage a large part of your household like the clothes and other textiles you possess. There are several kinds of moths, however, a few of these are common to most households.

What Do Moths Eat?

Moths are known for having nectar, however, their diet is not restricted to this. For reproductive purposes, moths consume a variety of liquids to provide themselves with a source of energy. Their diet isn’t particularly appetizing but they also eat sap, fruits, feces and rotten animals.

Moths are known to look for food during night time and therefore they do not decide on what to eat based on its color. Their smelling powers help them detect food easily. The moths we discussed in the previous section feed on clothing, hair, fur, leather, furniture, wool and milk powder. When you notice small holes in your clothes, they’ve probably been created by moths. However, many adult moths do not consume anything at all.

What Eats Moths?

Many animals are known to feed on moths as well as butterflies. Many of the nocturnal predators are known to feast on moths. Such as owls, arachnids, and flying mammals. Lizards are also known to eat moths very frequently. Some bears also may eat them like the Grizzly Bears. Moths are sometimes even eaten by humans. Countries like South Africa consider moths an option for their meal.

How Long Do Moths Live And What Factors Affect Their Lifespan?

Moths usually live for a minimum of 8 months and may survive for a longer period as well. The lifespan of moths depends on the strategy used by them in order to survive winters. Brown house moths and white shouldered house moths can live up to a year.  Their lifespan depends on several conditions such as the temperature.

How Do Moths Enter Your House?

There is a huge chance that your clothes may have been damaged by moths sometime in your life. It sure is not pleasant to discover this but the most important question is how did moths enter your house? 

Moths can enter your closets and storage in different ways. Most of the times they just fly through doors and windows that are left open. However, sometimes they just accompany the second-hand shopping you do at thrift stores, garage sales, and similar places.

Other times they may enter your house through your shed, tiny crevices or cracks in your house that you would not have noticed. They may also be introduced by bigger rodents and birds.

Another source for them to enter is rotten or contaminated food. Pantry moths eat rice, nuts, grains, flour, etc. It’s best for you to look in corners around your house or look for small cracks in the walls and doors.

The Conclusion of Moth Facts:

There are several varieties of moths that you can find on this planet, but only a few of them are commonly found in homes. Once a moth lays an egg in your house, it may lead to infestation so be careful and be on the lookout for these flying insects. If you discover an infestation, you must identify the moth and its breeding material. Once this is done, an appropriate solution can be devised. Even though chemical control is not recommended, you may have to use pesticides in some cases. A simpler and short-term solution to prevent infestation is to maintain hygiene by vacuuming bits of foods and cloth.
