Most spiders do not bite humans, and they only attack when instigated. A spider bite is commonly not harmful. If you have a spider bite on your eyelid, it may cause symptoms like inflammation, itchiness, or redness. This is only in the case of regular ones. Things go differently if you get bit by a venomous spider. In such a situation, we need to get to the poison control center for help immediately.

Let’s look at different types of spiders that bite and their effect on the human body. Furthermore, we will also look at a specialized treatment plan for relief.

Types of Venomous Spiders

Usually, venomous spiders are found in the South American region. These venom-containing spiders may bite on the eyelid or any other part of the body and release it into the bloodstream. This is their mechanism to kill and eat prey.

The venom poses many types of infections, both local and systemic. Moreover, if they are not treated on time it can result in fatality.

Black Widow

A black widow spider, as the name indicates, is black and shiny with long legs. May or may not have an orange marking on the underside. The venom or toxin released from this type of spider bite on an eyelid or other place is categorized as a neurotoxin, i.e., it affects the brain.

The bite wound would immediately show the toxin’s presence in terms of a sharp sting. Often not much reaction is seen at the bite site.

Brown Recluse Spider

Here are some indicators to identify a brown recluse spider. Firstly, as the name indicates, it has dark brown or golden type legs. It has six eyes instead of the usual eight with a body of half an inch. If you spot such a spider, plan to get rid of it as it can bite on various parts of the body, including the eyelid.

This spider’s bite sends the normal healthy tissues of the body into necrosis.

Brown recluse spiders are found in dark spaces and come out at night. They usually do not bite until disturbed.


This spider is very well known amongst people. A black-colored spider that bites and pierces through the human skin to release its venom. They are large and hairy spiders who do not bite until messed with.

Specific Symptoms Of a Spider Bite

The bite from a black widow spider does not feel more than a little prick. Extreme pain follows later on. If you see two red dots on the eyelid, there is a possibility of black widow spider bite over there. The venom shows its effect on the brain, may increase salivation, heart rate, numbness, or cause a tingling sensation. It can be fatal in children and the elderly.

When it comes to a brown recluse spider, the bite is painless and starts to destroy the surrounding tissues. At first, it is painless. But as time passes, it becomes itchy and quite painful.

It may or may not get better after two to three days. If the toxin after spider bite has started tissue necrosis, a scab will form, leaving a scar behind. In some cases, the venom causes kidney failure, anemia, chilling, weakness, etc.

Finally, coming to a tarantula, it will tear through the skin and inject venom. After it bites, the skin site e.g., an eyelid, would have tiny red bumps on it and send the person in allergic shock.
