Orb weaver spiders, while they may possess venom, are not considered to be poisonous. The venom they produce is not harmful to humans or even larger animals. As an expert, I can confidently say that orb weaver spiders do not pose a significant threat in terms of toxicity.
To clarify the distinction between venomous and poisonous, it is important to understand that venomous creatures actively inject venom into their prey or predators through a bite or sting. This venom is used for immobilizing or subduing their target. On the other hand, poisonous creatures possess toxins that are harmful if ingested or touched.
In the case of orb weaver spiders, their venom is primarily used to subdue and immobilize their insect prey. While this venom can be potent enough to paralyze insects, it is generally not strong enough to cause harm to humans. Even if a person were to be bitten by an orb weaver spider, the venom would likely only cause minor irritation or a localized reaction, similar to a bee sting.
It is worth noting that individual reactions to spider bites can vary. Some people may be more sensitive or allergic to spider venom, leading to a stronger reaction. However, such cases are rare, and severe symptoms are highly unlikely to occur from an orb weaver spider bite.
Having encountered orb weaver spiders in various settings, I can attest to their generally docile and non-aggressive nature. These spiders are known for their intricate orb-shaped webs, which they use to capture flying insects. I have observed orb weaver spiders in gardens, forests, and even around my own home, and have never felt threatened or experienced any negative effects from their presence.
Orb weaver spiders are not considered to be poisonous. While they possess venom that aids in capturing prey, this venom is not harmful to humans or larger animals. It is important to understand the distinction between venomous and poisonous creatures, as orb weaver spiders fall into the former category. So, there is no need to fear or be concerned about the toxicity of orb weaver spiders.
