Spider control can be a major concern for homeowners - particularly for those who live in the southwest.
There are about 3,000 species of spiders throughout North America, but only two in the southern and western United States can cause serious harm when accidentally disturbed - the black widow and brown recluse.
Types of Spiders
Black widow (Redback) spiders
Are most recognized for the red hourglass shape under their abdomen. This spider gets its name from the popular belief that the female black widow spider eats the male after mating, although this rarely happens. Black widows are poisonous when ingested during the first 17 days of their life.
Lately Reports of poisonous redback spiders are increasing among people living in new developments around Dubai.
Residents in communities such as Emirates Hills and Al Furjan in Dubai, and Al Ghadeer in Abu Dhabi, have encountered the small spider in their gardens during the hotter weather.
No one has been bitten, although many were shocked that the potentially deadly spiders are in the UAE and so close to their homes.
Redbacks are not indigenous to the UAE and are thought to have been brought over in packing containers from Australia, they have since spread throughout the country.
Brown recluse spiders
Have a characteristic dark brown violin marking on their back. These spiders often infest cedar shake roofs and spin irregular webs, which are used as a retreat.
The common house spider
Is usually the spider most often encountered indoors. It is a nuisance pest, probably more because of its webs than the spider itself. The house spider is found worldwide.
About 300 species of jumping spiders are found in the United States and Canada. Unlike most spiders, jumping spiders are active during the daytime and seem to like sunshine.
Long-bodied cellar spiders
Are commonly referred to as "daddy-long-legs" because of their very long, thin legs, and as their name implies, are found in dark and damp places like cellars and basements.
Unlike most spiders, wolf spiders don’t hunt with webs. Instead, they chase their prey using their fast running ability. These spiders are often big and hairy which alarms some people, but they are primarily nuisance pests.
Crab Spiders usually have short, wide, flat bodies. The first two pairs of legs are larger than the back legs, and are usually held open so that the spider can easily grab its prey. They usually walk sideways or backwards, and use just their back legs. This is where they get their name.
All crab spiders have eight eyes, and the eyes on the edges of their cephalothorax are often raised up on bumps, so they can see in all directions. These spiders have small fangs compared to other spiders, but their venom acts quickly to paralyze their prey.
