  • treatment
  • Trombicula are also known as red bugs, scrub-itch mites and berry bugs. They are parasites to many species of animals.

    About 30 of the numerous species in this family, attach to various animals, including humans, in their larval stage.

    The two species that cause trombiculosis in dogs and cats are: Neotrombicula autumnalis and Straelensia cynotis.

  • Lesions are seen most commonly on the feet, but the face, including the ears, and ventral body can also be affected. Dermatological signs normally include local erythema, with papules, scales, crusts and pustules present in some cases.

    Trombiculosis usually occurs at the end of summer (between late August and September) and affects animals with outside access. Humans may also be infested.

  • Fipronil and other acaricides can be successfully used to kill the mites.

    Reinfestations are common in animals exposed to mites, therefore preventative measures should be taken. Topical spray treatments may be repeated every 3-5 days in order to prevent reinfestation. Frequent spraying of the commonly affected areas such as paws and ventral abdomen may be more effective than less frequently applied spot-on preparations.

The threat of arthropod parasites for human and animal health is increasingly recognized world wide. The hazard of these insects or acarids is linked to both the direct lesions

they generate as well as their ability to transmit diseases.

How does the model work ?

FleaTickRisk is a unique and dynamic model encompassing an ongoing collaboration between researchers. The maps generated allow visualisation of the risk of infestation by ticks and fleas.
