Contracting a Hobo spider bite requires prompt treatment. Victims should immediately receive first aid treatment after getting bitten and go to the doctor for proper diagnosis. It would be of great help to the diagnosis if the hobo spider is captured and examined by the doctor. The victim should also take notice of any symptoms he/she experiences after the bite as the treatment method will be designed according to the symptoms displayed by the individual. Treatment is often incorporated with preventive measures to avoid spider bites in the future.

What is a hobo spider ?

Hobo spiders pertain to brown-colored spiders with legs covered with short hairs and with a V-shaped pattern in their abdomen. They shouldn’t be confused with the brown recluse spider which has a violin-shaped pattern on its abdomen. Hobo spiders could be half inch to three-fourth inch long with two palps. Male hobo spiders have more swollen palps than their female counterparts. However, female hobo spiders have larger abdomens than the males.

Hobo spider bites tend to occur more frequently from mid-summer to fall. These spiders only become aggressive when attending to their egg sacs and when humans come close to their webs. They also bite humans when they feel threatened, such as when getting stuck in beddings and clothing.  Hobo spiders are common in Europe, US and Canada and love to dwell in gardens and fields. They spin non-sticky funnel-shaped webs to trap their prey. Female hobo spiders can live up to a couple of years while the males live for a few months only.

Hobo spider bite – Stages and Timeline

Spiders transmit their venoms through bites. It is important to know how to identify a hobo spider bite in order to take the necessary steps in preventing permanent skin damage.

  • Mosquito bite-like redness

A hobo spider bite is remarkably painless and victims do not even know they had been bitten by a spider. The bite could only be noticeable by some redness and hardening due to the skin’s reaction with the spider venom, resulting in the surrounding skin tissue to burn off. All of these are visible manifestations within 30 minutes after the actual bite has occurred.

  • Emergence of blisters

The tissue surrounding the bite site further hardens and a 5 to 15 cm red welt will develop. Blisters will also form and break open, releasing discharges. These will happen within 12 to 48 hours after sustaining a bite.

  • Scab formation

Scab will form after the blisters had ruptured. This will become more pronounced and features a bull’s eye appearance. The scab will eventually fall off and heal usually within 3 weeks after the bite. In severe cases of tissue loss, it may take up to 3 years for the lesion to completely heal. The damaged tissues may need to be removed surgically.

The venom injected by the hobo spider might also cause systemic symptoms which vary from person to person. Among the common complaints associated to a hobo spider bite include severe headache, flu-like symptoms, vomiting and nausea. Some victims may also complain of impaired vision, fatigue and temporary memory loss.

Hobo spider bite treatment

Hobo spiders are venomous, but their bites do not always lead to fatality because hobo spiders do not always inject venom when they attack humans. It is for this reason that some victims do not exhibit any symptoms. Even so, a bite from hobo spider could be extremely dangerous especially for individuals who have hypersensitivity to these bites. A hobo spider bite could result in skin grafting, malfunctioning of the bone marrow or amputation. That is why the victim should immediately be taken to the doctor after giving first aid treatment.

It would be best to safely capture the hobo spider, whether alive or not, to help doctors plan the right treatment. The following are the dos and don’ts when giving victims first aid treatment:


  • Wash the affected site with soap and water.
  • Apply cold compress to prevent the venom from spreading further.
  • Keep the affected area in a high position.


  • Don’t wash the spider bite with hot water as this will spread the venom faster.
  • Don’t apply warm compress as this will intensify the flow of blood which would spread the venom more quickly.
  • Don’t suck or touch the bitten area.

The best way to prevent sustaining a hobo spider bite is to wear protective clothing when working in places where hobo spiders thrive.
