THE Ambulance Service of NSW is urging local residents to be vigilant- as the weather warms up spiders season kicks into gear.

Since July 1 2014 NSW paramedics have received 55 calls involving suspected spider bites.

Funnel-webs, red-backs and white-tail spiders are considered the most aggressive spiders.

But a fatal spider-bite has not been recorded in 35 years, invertebrate keeper at the Backyard to Bush exhibit at Taronga Zoo James Baxter-Gilbert said.

"There has not been a confirmed death from a spider-bite since 1979," he said.

"Most spiders do not offer any threat.

"So people really don't need to panic about them."

Mr Baxter-Gilbert said the majority of spiders are timid and will run away if given the chance.

He added some confrontations occur when spiders hide in dark moist areas, such as boots.

Funnel webs have even been known to hide in swimming pools as they can survive under water for several days.

NSW Ambulance Inspector Giles Buchanan recommended clothing and shoes are checked before they are worn.

"Paramedics have attended many cases where people have put boots on and gloves and have been bitten by spiders and even snakes which were hidden inside," he said.

Mr Baxter-Gilbert also added people should be cautious when reaching into areas they cannot see and even consider wearing gloves.

If bitten by a funnel web spider NSW Ambulance said a pressure mobilisation bandage should be applied to bites on a limb or pressure to bites affecting other areas.

The patient should be kept still and Triple Zero should be called.

Bites from red-backs, white-tails and other such spiders should be treated with ice and medical treatment should be sought if symptoms develop, but should be sought immediately for spider-bites to children.

Keep an eye out for red-back spiders, said Mr Baxter-Gilbert, avoid picking them up and treat all spiders with respect.

"Arachnophobia is the most common phobia in the world," he said.

"But spiders pre-date humans and for millions of years have played an integral role in our ecosystem.

"Give them the respect they deserve; they only give a nip if they're provoked so 99.9 percent of the time just leave the spider where they are and you'll be fine."

Those who wish to remove the spider can relocate it with a takeaway container, Mr Baxter-Gilbert said.
