How are ticks dangerous to hedgehogs? - briefly

Ticks transmit pathogens (e.g., Borrelia, Anaplasma) and feed on blood, leading to anemia, immune suppression, and potentially fatal illness. Heavy infestations can severely weaken hedgehogs and increase mortality risk.

How are ticks dangerous to hedgehogs? - in detail

Ticks present several direct and indirect threats to hedgehog health. Their blood‑feeding behavior can cause measurable blood loss, especially when multiple parasites attach simultaneously. In small mammals, even modest hematologic depletion may lead to anemia, reduced stamina, and impaired thermoregulation.

Pathogen transmission is a primary concern. Ticks serve as vectors for a range of microorganisms that affect hedgehogs, including:

  • Borrelia burgdorferi – the agent of Lyme disease, which can provoke joint inflammation, renal dysfunction, and neurologic signs.
  • Anaplasma phagocytophilum – induces fever, lethargy, and neutropenia, compromising immune defenses.
  • Ehrlichia spp. – produces similar systemic effects, often resulting in weight loss and splenomegaly.
  • Babesia spp. – a protozoan that invades red blood cells, causing hemolytic anemia and, in severe cases, fatality.
  • Rickettsia spp. – can trigger vasculitis and skin lesions.

Some tick species secrete neurotoxins that cause temporary paralysis. When the toxin interferes with neuromuscular transmission, hedgehogs may experience weakness, difficulty moving, and, if untreated, respiratory failure.

Secondary complications arise from tick attachment sites. Mechanical irritation leads to localized inflammation, dermatitis, and ulceration. Open lesions provide entry points for opportunistic bacteria, increasing the risk of cellulitis and systemic infection.

Reproductive performance may decline under parasitic stress. Anemic or diseased individuals often exhibit reduced mating activity, lower litter size, and diminished offspring viability, affecting population stability.

Effective management includes regular inspection of captive and wild hedgehogs, prompt removal of attached ticks using fine forceps, and application of veterinarian‑approved acaricides. Monitoring blood parameters and screening for tick‑borne pathogens allow early intervention, reducing morbidity and mortality associated with these ectoparasites.
