What Happens if You Get Bit by a Vampire Moth? | Important Facts!

There are thousands of different species of moths, and some people may be surprised to learn that there are moths that feed on the blood of vertebrates, including humans. These blood-sucking moths are called vampire moths.

What happens if you get bit by a vampire moth? Vampire moths have a proboscis, a straw-like projection on their mouth that allows them to pierce and penetrate human skin, piercing it back and forth until blood is accessible. It works in the same way that mosquitoes do when sucking blood. Their bite will cause slight pain, redness, and soreness around the wound.

It is true that there are moths that bite and suck blood from humans. But the question is, “Is there anything to be afraid of?”

What Are Vampire Moths?

What Are Vampire Moths

The vampire moth, also known as “Calyptra thalictri” belongs to the genusĀ Calyptra, a family of moths in the subfamily Calpinae of the Erebidae family. Vampire moths primarily feed on fruit juice and nectars. They use their proboscis to penetrate fruit skin and suck fruit juice. Only male vampire moths are known to suck blood from vertebrates. Male vampire moths drink blood for salt or sodium content, which is transferred to the female vampire moths through sperm during mating, which is said to be beneficial for their offspring.

Where Do Vampire Moths Live?

Where Do Vampire Moths Live

The first vampire moth was discovered in Siberia, and studies show that vampire moths have been found throughout Central and Southern Europe. They are also native in Africa and Asia.

Like other common moths, vampire moths can be found practically anywhere, where there are plants such as in fields, forests, mountains, and gardens. Their caterpillars or vampire moth larvae eat the leaves of any common plants.

Do Vampire Moths Bite?

Vampire moths do bite. Their bite is similar to that of a mosquito bite. Vampire moths have a proboscis, which they use to repeatedly penetrate the skin until blood is accessible. Then, they bury their straw-like mouth even deeper and suck blood. They also use their proboscis to penetrate fruit skin and access fruit juice, just like they do when they suck blood from humans and other animals. Their bite can cause minor wounds and discomfort, as it can be slightly painful.

Here is a video about the vampire moth discovered a few years back that shows how it bites and feeds on human blood:

Are Vampire Moths Deadly?

Vampire moths can bite and drink human blood; however, they are considered harmless. As of the moment, there is no record that a human has died because of vampire moths.

Do Moths Carry Disease?

Vampire moths’ bites in most cases do not contain any diseases, viruses, parasites, poison, or venom that can harm humans. Their bites do not cause any severe reactions, so there is nothing to worry about.

How Do You Treat Moth Bites?

If a vampire moth has bitten you, wash the wound with soap and water as soon as possible. There will be some redness and mild pain on the bitten wound. To minimize redness and pain, wrap an ice pack around the wound. There’s no need to be concerned because the majority of vampire moth bites are mild. Within minutes to an hour, the pain will go away. Additionally, antibiotic cream purchased over the counter can be used to prevent infection of the wound.

Do Vampire Moths Hate Smoke?

Do Vampire Moths Hate Smoke

Not only do vampire moths hate it, but most common moths like clothes and carpet moths are known to be repelled and eliminated by smoke. Vampire moths can be effectively eliminated using smoke, foggers, or smoke bombs. They will be suffocated and eliminated instantly by the toxins in the smoke. Vampire moth eggs and larvae, on the other hand, have a better chance of surviving.


Vampire moths, also known as Calyptra thalictra, are nectar and fruit juice feeders. These moths have a proboscis, which they utilize to pierce fruit skin and suck juices and nectars from plants. They are called vampire moths because they have been discovered to suck blood from humans. However, only male vampire moths have been observed sucking blood from humans and animals.
