Spiders come in a variety of colours, from solid black and brown to yellow, green, and even blue. Some species can also be brightly coloured.
Spiders range in size from less than 1mm to almost 10 cm, however most of the spiders encountered in our homes are roughly 1cm long.
Spiders are arachnids, eight-legged invertebrates that have two body segments, eight legs, and no wings or antennae. They have two primary body parts – the cephalothorax and the abdomen – and usually have eight eyes. They produce silk from special glands, which they use to make webs to catch prey. Spiders are predators, eating insects and other small animals. They are found on every continent except Antarctica.
Where to find a spider?
Spiders are often found in dark, secluded areas like basements, attics, and closets. They can be identified by their long legs and distinctive body shape. Some species also have distinctive markings on their bodies, such as stripes or spots. They can be found in webs or wandering around on the ground.

Problems caused by spiders
Spiders can cause a variety of problems for humans. Some of the most common problems include:
- Allergic Reactions: Some people may be allergic to spider bites or their webs and can suffer from a range of symptoms including pain, swelling, and itching at the affected area. In some cases, a spider bite may result in a more serious allergic reaction, such as anaphylaxis.
- Disease Transmission: Some species of spiders, such as the brown recluse and black widow, can transmit dangerous diseases such as necrotic arachnidism and neurotoxicosis.
- Property Damage: Spider infestations can lead to property damage by eating away at wooden structures, fabric, and paper. In addition, their webs can be difficult to clean up and may cause a nuisance.
- Pest Control: Spiders can be a nuisance to humans because they feed on other insects and pests, such as flies and mosquitoes. While this can be beneficial in some cases, it can also lead to an increase in the number of insects in the home.
- Fear Factor: For some people, spiders can be a source of fear and anxiety. This can lead to a reluctance to enter certain areas of the home or to go outdoors.
Why do I have spiders
There are several potential reasons why you may have spiders in your home. Spiders are common in both indoor and outdoor environments, and can enter your home through cracks, crevices, and other small openings. They may also be attracted to your home by the presence of food sources, such as insects, or by the presence of moisture. Additionally, spider webs may be constructed in areas of your home that are dark and undisturbed, such as attics, basements, and crawl spaces.
How worried should I be about spiders
The level of worry you should have about spiders depends on the type of spider and the situation. Generally speaking, most spiders are harmless and will not cause any harm to humans. However, there are some species that can be dangerous, such as the brown recluse and black widow. In these cases, it is important to take the necessary precautions to ensure your safety. If you are unsure of the type of spider present, it is best to seek professional help.
