Do Crickets Transmit Diseases? The Truth Revealed

Have you ever been curious about the relationship between crickets and disease transmission? Perhaps you’ve been wondering whether it’s safe to have crickets in your home, or if they can cause any health issues for you or your pets. Well, the truth is that while crickets do have the potential to transmit certain diseases, the risk of this happening is generally quite low.

Before we dive deeper into this topic, it’s important to understand a bit more about crickets themselves. These small, chirping insects are often found in warm, humid environments, such as gardens, fields, and sometimes even inside our homes. While they may be considered a nuisance by some, they can also play a valuable role in the ecosystem as a food source for certain wildlife.

Do crickets carry diseases?

While there have been some cases of crickets transmitting diseases to humans or other animals, these occurrences are generally quite rare. According to the Centers for Disease Control and Prevention (CDC), there are only a few known diseases that can be transmitted by crickets:

  • Salmonella: This is a type of bacteria that can cause diarrhea, fever, and abdominal pain. Crickets can become contaminated with salmonella if they come into contact with feces or other materials that contain the bacteria.
  • Leptospirosis: This is a bacterial infection that can cause flu-like symptoms, such as fever, headache, and muscle aches. While it is possible for crickets to carry leptospirosis, the risk of transmission is considered to be low.
  • Plague: Perhaps the most well-known disease associated with crickets is the bubonic plague, which is caused by a bacteria called Yersinia pestis. While it is possible for crickets to become infected with this bacteria, the risk of transmission to humans is considered to be very low.

How do crickets transmit diseases?

The most common way for crickets to transmit diseases is through direct contact with an infected cricket or its bodily fluids. For example, if a cricket has come into contact with feces containing salmonella bacteria, it could then pass that bacteria on to a person or animal if they touch or consume the cricket.

It’s also possible for diseases to be transmitted indirectly through other materials that crickets come into contact with. For example, if a cricket walks across a surface that has been contaminated with salmonella, it could then transfer that bacteria to another surface or person that it comes into contact with.

How can you reduce the risk of disease transmission from crickets?

If you’re concerned about the potential for crickets to transmit diseases, there are a few things you can do to help reduce the risk:

  • Practice good hygiene: Wash your hands regularly, especially after handling pet food or coming into contact with crickets or other insects.
  • Keep your pets’ living areas clean: Regularly clean out your pet’s enclosure and any bedding or substrates to help minimize the risk of disease transmission.
  • Choose a reputable supplier: If you purchase crickets for your pets, make sure to choose a supplier with a good reputation for quality and cleanliness.

Can crickets transmit diseases to plants?

While crickets can cause damage to plants by feeding on leaves, stems, and roots, they are not known to transmit diseases to plants.


While the thought of disease transmission from crickets may be concerning, the risk of this happening is generally quite low. By practicing good hygiene and choosing a reputable supplier for your pet’s crickets, you can help minimize any potential risks.
