Frequently Asked Questions


How did I get daring jumping spiders?
Like other arachnids, daring jumping spiders, also known as bold jumping spiders enter homes in search of protection, warmth and food. Though they prefer to live outside in barns and sheds, these pests occasionally find their way indoors. Loose-fitting screens and gaps around doors or windows are common access points. Their natural habitats include grasslands, gardens and open wooded areas.


How serious are daring jumping spiders?
Daring jumping spiders are non-aggressive, do not pose any serious danger to humans, but may bite in self-defense. Bites typically result in slight pain and small, itchy bumps on the skin that heals quickly. However, the spiders appearance, their quick movements, and their ability to jump may be unsettling.


What are the signs of a daring jumping spider infestation?
The most obvious evidence of daring jumping spiders is their appearance during daylight hours when they are most likely to be seen hunting and seeing them in their sheltered locations.


Do daring jumping spiders bite?
Daring jumping spiders may bite humans in self-defense. Their daytime hunting habits help reduce the number of human bite cases. If bitten, symptoms usually involve slight pain, itching and local reactions such as red bumps that last from 1-2 days.

Understanding Daring Jumping Spiders


Appearance

The daring jumping spider, also known as the bold jumping spider, has a distinctive black or dark-gray hairy abdomen.

Spots: Most members of this species have three white spots on their abdomen, but in some species the spots may be red or orange.

Size: The adult female is about 3/8 to ¾ inch long, and the adult male is about ¼ to ½ inch long.

Hair: Tufts of hair over the male spider’s eyes give them the appearance of having “eyebrows”.

Legs: Daring jumping spiders have eight legs with bands of white spaced up and down the legs

Eyes: eight eyes (the center two are very large and prominent)

Mouth: mouthparts that are iridescent blue or green in color

Diet

The daring jumping spider eats a range of insects and other spiders, and these spiders are known prey for dragonflies, birds and lizards.

Activity

Like most species of the jumping spider group, daring jumping spiders are solitary hunters who are active during the day. Jumping spiders have extremely good vision, a characteristic useful for observing both prey and predators.

Distribution

The daring jumping spider is one of the most common species found in North America. Phidippus audax is generally found in North America. Distribution ranges from southeastern Canada to British Columbia and as far south as northern Mexico to Florida.

Habitat

The daring jumping spiders are very diverse and are frequently seen in urban, suburban and agricultural habitats. Their natural habitats include grasslands, prairies old fields backyards, gardens and open woodlands. This species will enter homes and outdoor structures, but isn’t as likely to be seen in a home as it is in barns, storage sheds, on tree trunks and under limbs or ground litter.

Webs

These spiders do not build webs to catch prey, but they do build protective webs.

Reproduction & Life Cycle

Daring jumping spiders reach maturation in the springtime, and mating begins around late spring or early summer. Reproductive females will produce as many as eight eggs sacs per year with each egg sac containing from 30-170 eggs. The spiders living in the warmer portions of their distribution range usually live longer and produce more offspring.

Prevention Tips

Prevention of daring jumping spiders begins with making sure the population of insects that serves as food for the spiders is kept to a minimum and that holes, cracks and gaps in the home’s doors, windows and foundation are properly sealed to prevent entrance into the home’s living space. In addition, removing ground litter that serves as harborage for spiders is also helpful. Should the homeowner need assistance in control of these or any other spider, contact your pest management professional and request an inspection. Your pest management professional can then use his inspection findings to prepare a comprehensive pest management plan that will effectively and efficiently deal with the specific pest problem.
