Spider Treatments

Envirotechnics offers cost effective pest control for spider infestations

Spider infestations might indicate that you have an underlying pest problem. As with most pest management programs, an Envirotechnics Integrated Pest Management (IPM) approach is an integral part of successful spider management.

Australia has over 2,000 species of spider. Some of the more common ones include the redback spider, wolf spider, black house spider, funnel web spider, huntsman spider, white tailed spider, mouse spider, and trap door spider. We have both webbing spiders (those that build webs) and ground dwelling spiders and most prey on small insects or other spiders.

Envirotechnics’ technicians will know precisely where to look and what to do with spider infestation and spider control treatments

At Envirotechnics, spider management procedures are preceded by a thorough inspection of the entire premises to define the extent of the problem. Treatment protocol are then put in place to remove them and keep them out of your home.

Hunting spiders such as the Huntsman and White Tail spider are difficult to manage with residual products as there is no web to treat. In these cases, it is usually best to target the spider’s food sources (such as small insects) instead.

How can I control spiders?

In Australia, spiders tend to prefer wet weather and can make their homes almost anywhere including in swimming pools, in the garden, most urban areas and in your home regularly. 

The majority of spiders build some kind of web. Most webs in your garden will be home to harmless spiders which may even be beneficial by catching flies and other insects.

Many harmful spiders are relatively small and nocturnal. They spend the day in hiding places like leaf litter close to their nests, which, in some cases, are little more than small balls of what looks like cotton wool. One such spider common in Western Australia is the Redback Spider.

Keep an eye out for their small nests in sheltered sites such as on the undersides of garden furniture, around plant pots or under children’s toys outside or internally near doors and windows.

By destroying spiders’ webs, you will not destroy the spider. Many spiders will reconstruct their unsightly webs of sticky threads in a few hours. It is important that you destroy the mature spiders by spraying them with a proprietary insecticide or by squashing them.

If, like most people, you have a fear of spiders, call the Envirotechnics team to meet your spider pest control needs. Our expert technicians can advise on everything from preventative measures to pest control solutions for a major infestation of a number of spider species.


Q1. When are spiders most active
Spiders are most active in the Autumn as they seek warm shelter to prepare for the cooler months, as well as to seek a mate and lay eggs. 
Q2. What are the most common spiders in Western Australia

There are numerous species of spiders in WA, but the most common are Redback Spiders, Black House Spiders, Daddy Long Legs, Huntsman, and White Tailed Spiders.

Q3. What are signs of a spider infestation

Webs everywhere
Spiders love to build web as it is their home and trap for food. This is one of the most noticeable signs of spiders in your home.

Excess of flying insects
Insects are a spiders favourite food source, and their webs are designed to catch these insects and trap them. If there are a lot more flying insects around your home, spider will be more inclined to build their home to take advantage of the food source.

Spotting more spiders around the home
This is one of the more obvious signs, but worth mentioning that if you see a spider there are probably more around. Finding one could mean that you’ve stumbled onto a potential breeding ground. It takes two spiders to turn your home into a colony, with hundreds of babies running around.

Q4. What to do when you find a spider eggs sac

Spider eggs savs are made of silk that is woven in a way very similar to a web. Their appearance depends on the spider, but most are white, cream, or brown in colour.

You can wrap a cloth around the end of a broom and sweep the egg sac away or use a vacuum cleaner to suck it up and use a sealed plastic bag to dispose of it. Use caution when getting rid of an egg sac because a false move could send dozen baby spiders scattering all over.
