Dangerous spiders        

It is estimated that there are more than 400,000 spider types on each continent except Antarctica. However, only a few spiders come with lethal bites. Thus, these pests may bite smaller creatures rather than humans. It only means that the venom released by spiders is rarely deadly to us. Meanwhile, the problem is when the skin lesions create an allergic reaction, which can be fatal. With this, it is essential to know which spiders are dangerous.

The following are some poisonous spiders you need to avoid.

Black widow spider

You can quickly identify the black widow spider due to its shiny black and red-yellow design on its abdomen. This type of spider is usually found in the West and South of the United States. Black widow spiders produce a venom which is a neurotoxin. It can produce pain in the area bitten.

The worst is that the venom can spread to the abdomen, chest, and entire body. The bite of this spider can be easily identified. The bite can make two puncture marks on your skin.

Hobo spider

Even though it is not considered among the most dangerous types, hobo spiders can cause serious side effects, if it bites you. Usually, these spiders hide in your basement and other undisturbed spaces. They are also hard to identify since their appearance varies.

Brown recluse spider

The brown recluse spider is among the most poisonous spiders in the United States. It can be commonly found in the Southern and Midwestern states. It has a light brown to dark brown color and can be a little bigger than a penny.

The venom of the brown recluse spider can lead to severe lesions by destroying the skin tissue. If you got bitten by a brown recluse, it is advisable to seek a medical attention immediately.
