Understanding Spiders
Spiders, although crucial to our ecosystem, can become uninvited guests in our homes and workplaces. In Australia, about 2000 described spider species exist, with a small yet significant number being a potential threat to humans and pets. While not all spiders are aggressive, some may bite when threatened, causing varying degrees of discomfort and in rare cases, severe reactions.
Signs of a Spider Bite
It’s vital to recognise the signs of a spider bite and act promptly by engaging a pest control spider treatment. Spider bites may lead to symptoms such as:
- Skin narcosis
- Redness and itching.
- Nausea
- Vomiting
- Sweating (perspiring)
- Dilated pupils
- Uncontrollable muscle spasms
- Unconsciousness

SPIDER CONTROL FAQS
How do I get rid of spiders?
The best way to get rid of a spider problem is to call in spider exterminators. At Eco Pest Group, we use a combination of the following methods to get rid of spiders.
Using residual microtechnology, we target all the hotspots of spiders such as roof voids, internal and external of your property.
The products we use are safe for you, your family and pets while providing outstanding knockdown and residual protection.
Removing cobwebs some weeks after the treatment is a great way to monitor the effectiveness of our treatment.
What are the signs of a spider infestation?
- There are spider webs around your home or garden
- You see spiders
- There are spider eggs (spider egg sacs are white to cream in colour. They’ll usually be covered in the spider’s silk and then attached to something, like a fence, crevice in a wall or in a nook or cranny)
Are spider treatments safe for my pets and me?
The spider control products Pest Aid technicians use are very low in mammalian toxicity and designed to be specific to spiders and insects, all precautions will be taken to ensure occupants’ safety.
Do I need to vacate my house during a spider treatment?
If we are treating the internal and the roof void as well as the external for spiders, Pest Aid recommends that you stay away from the treated areas until the product is dry (usually around 1-2 hours depending on the weather).
Can I do my own spider control?
All spider control products and application equipment that are commercially available are only effective for short-term control, Pest Aid Technicians are fully licensed, trained and equipped to control spiders long-term.
Does pest control get rid of spiders?
Absolutely, and it’s the most effective way to get rid of spiders and prevent future infestations, with annual spider treatments.
