  • Diet: Fishing spiders are named for their tendency to catch and eat small fish and aquatic insects.
  • Hunting: While other types of spiders detect the presence of prey by way of vibrations in their silken webs, fishing spiders use ripples in the water.
  • Habitat: Covered in tiny hydrophobic hairs, fishing spiders are able to walk on the surface of the water and even dive below in order to catch meals. Some types of fishing spiders dwell in trees and often make their way inside homes where they become nuisances.


What Do Fishing Spiders Eat?
As is the case with most arachnids, fishing spiders primarily prey upon insects, especially those that live near the water’s edge.

They also hunt down small fish and aquatic animals, such as frogs.


Female fishing spiders care for their eggs by weaving them together in a protective silken sac. Some species construct nursery webs and some carry the eggs around with them.

Life Cycle
Young hatchlings grow and develop by molting several times before achieving maturity.


  • Sighting: Look for adult spiders.
  • Skins: May notice discarded molts inside.
  • Water: Be mindful of activity on the surface of ponds or streams on private properties.

Problems Caused by Fishing Spiders

Although the arachnids are large and intimidating, fishing spiders are harmless to humans.

They may deliver a painful bite if grabbed or trapped against the skin, but fishing spiders are shy and would rather flee than fight. Their venom is not poisonous to humans.

Signs of Infestation

It is extremely rare for a large number or fishing spiders to infest a home.

Large Presence
If many of the creatures are spotted over a short period of time, it may be a symptom of a successful reproductive year which may make it appear as larger and more invasive pest infestation.

Prevention Tips

  • Seal Cracks & Holes: Taking certain precautions such as sealing cracks in walls, doors, and windows helps reduce the risk of fishing spiders finding their way inside homes.
  • Landscaping: Maintaining good landscape sanitation practices and limiting the use of exterior lighting may help reduce the presence of other insects that draw fishing spiders towards your home in the first place.

Tips for Removal from Home

Catch & Release
The shy spiders can be caught and released outside away from the home or vacuumed up.
