Have you found a spider at home? In this guide, I will talk about “how long does a spider live?” With the help of this information, you will be able to understand when your housemates will disappear and not interfere with you. I want to note that spiders’ lifespan is different according to the species. I will tell you about the exact lifespan of a spider. Read on and find out whether the pest will disappear on its own.

How Long Do Spiders Live?

Nowadays, there are more than 3,800 types of spiders, so it is difficult to determine which particular spider lives in your house. Most often, the life cycle of spiders lasts only two years, but sometimes these pests can live longer. Male spiders can also die immediately after mating.

Stages of the Spider’s Life Cycle

Spiders have three life stages. I will tell you about each of them in more detail below. All species have the same life cycle, and even the house spider’s lifespan is as described below.

  1. Egg stage. After the mating period, it takes about two weeks for the eggs to hatch. Some females carry eggs with them. Some species leave their eggs to their own fate and don’t take care of them.
  2. Little spider. The hatched spiders are very similar to their parents, only much smaller. At this stage, tiny insects are very vulnerable. Due to their rapid growth, spiders shed more often. Females are always larger than males, so they need more time to mature.
  3. Adulthood stage. This stage starts when the pest reaches the mature stage and can proceed to mate. Female spiders live longer. Males of some species die immediately after mating. Some spiders live for a long time, which can even reach 20 years.

Spider Species and Their Diseases

There are many types of spiders, and currently, the number equals 3,800. Each of these species can have its disease. To determine a spider’s condition, you need to identify its type correctly. Spiders are usually very fragile. Therefore, if you accidentally step on one, it will die. If you have a spider as a pet, it’s best to visit a veterinarian to find out more about its condition. Spiders cannot transmit diseases to humans, so you don’t have to worry about that.

The Life Expectancy of Spiders

The lifespan a spider has depends on the type you are dealing with. The average figure is tricky to determine since some species can live up to 1 year, while others can reach 20 years. Also, life expectancy depends on living conditions. The less attractive your place seems to these pests and the less food you provide them with, the less they will live.

As I have already mentioned, some insects can live longer. Some arthropods also die after mating, but it refers only to mates. To know how long a particular spider will live, you need to identify its type and gender. Specialists from pest control or a veterinarian can help you with this. The longer each stage lasts, the more the pest will live.
