Spiders in the workplace

By Ryan Graham, Health and Safety Professional · Published 20 October 2022 · Updated 24 October 2026

There are many species of spiders in Queensland, and some of them can be found in the workplace. The most common type of spider is the house spider, which is not harmful to humans. However, other types of spiders, such as funnel-web spiders and the redback spider, can be dangerous. The brown recluse and black widow are North American spiders. If you see a spider in your workplace, it is important to identify it before taking any action. A bite from a large (more than 2 cm), dark-coloured spider, especially in south-eastern Queensland, should be treated as a possible funnel-web bite. Redback spiders are about 1 cm long with a red, orange or pale stripe on the back of the abdomen.

Preventing spiders from entering your workplace

  • Keep the exterior of your building free of spider webs. Inspect the perimeter of your building regularly and remove any webs you find.
  • Seal any cracks or holes in the exterior of your building. Spiders can enter through very small openings, so it is important to seal any that you find.
  • Keep your workplace clean and free of clutter. Spiders like to hide in dark, cluttered areas. By keeping your workplace clean and tidy, you will make it less attractive to spiders.

What to do if you see a spider at work

  • If you see a spider in your workplace, there is no need to panic. Most spiders are not harmful to humans.
  • If you are unsure of the type of spider, it is best to contact a pest control professional for assistance.
  • Pest control professionals will be able to identify the spider and determine if it is dangerous.

What to do if you are bitten by a spider

  • If you are bitten by a spider, it is important to remain calm.
  • If a funnel-web spider bite is suspected, call 000 straight away, keep the person still and calm, and apply a pressure bandage with immobilisation. Do not wait for symptoms to appear.
  • Clean the wound with soap and water.
  • For other spider bites, including redback bites, apply an ice pack to relieve pain. Do not use a pressure bandage on a redback bite.
  • If the bite is painful or causes swelling, redness, or itching, seek medical attention.

By following these tips, you can prevent spiders from entering your workplace and keep yourself safe from their bites. If you do encounter a spider, do not hesitate to contact a pest control professional for assistance.
