Stickfast flea

Echidnophaga myrmecobii is a species of flea belonging to the Pulicidae family within the order Siphonaptera. Unlike most common fleas that move freely across the host's skin, this species acts as a sedentary ectoparasite. It primarily targets small mammals, and while it is not a direct agricultural plant pest, it is a significant concern for animal health management and biosecurity on farms.

The biology of this flea is characterized by a specialized attachment strategy. Once the adult female finds a suitable host, she embeds her mouthparts deep into the skin, becoming virtually immobile. This attachment allows for continuous feeding, which is critical for the development of eggs and the continuation of the species' life cycle, including the stages of egg, larva, and pupa.

The damage caused by Echidnophaga myrmecobii is largely dermatological. Because the fleas stay fixed in one spot, they cause localized irritation, inflammation, and secondary bacterial infections. Animals infested with these fleas exhibit significant discomfort, scratching, and potential secondary skin lesions that may lead to more severe systemic health issues.

Key indicators of infestation include:

• Visible clusters of fleas attached to thin-skinned areas such as ears or eyes.
• Localized skin inflammation and swelling.
• Formation of ulcers and crusts resulting from the feeding process.

Control measures are centered on environmental and chemical management. Since larvae develop in the environment (such as bedding or soil), sanitation is crucial. Pesticide application on the hosts using vet-approved products is the primary method to manage active infestations, complemented by the routine cleaning and treatment of animal enclosures to disrupt the flea's reproductive cycle.
