The nursery web spiders have a large and long leg span. Fortunately, these spiders are not fond of dwelling inside a house. They prefer tree trunks, vegetation, and building exteriors.

How Do You Kill a Huge Spider?

No matter how unpleasant they are inside our homes, it is not advisable to kill them. The giant house spiders keep the ecosystem balanced. However, if huge spiders are bothering you and your home, there are many quick and easy ways to kill them.

Here are some of the many ways to kill a huge spider:

  • Trap it inside a bottle or glass container.
  • Spray it with insect or bug spray.

Should I Worry About Spiders in My Room?

It is okay to have spiders in your room, but that depends on the kind you found. Some spiders like to hide in areas with moisture, while others like drier environments like the corners of your rooms.

The spiders that we usually see in our homes tend to hide and live in dark and quiet areas. However, if they totally bother you, try catching and releasing them outside or spraying a spider-repellent to keep them away.

What Happens if I Get Bit by a Black Widow?

Black widows have a venom that could affect your nervous system. You may experience swelling, redness, burning sensation, and severe pain in the affected area if bitten by a black widow. You may also show other symptoms like vomiting, difficulty breathing, stiff muscles, sweating, itching, tremors, swollen eyelids, and abdominal pain.

It is best to seek medical help and rush to the emergency department right away. Black widow bites are especially fatal to younger children as they may not hold the pain and its symptoms very well.

When Should Spider Bites Concern Me?

You should be concerned about a spider bite if it:

  • Continues to swell.
  • Has fluid coming out of the bite.
  • If you experience any pain that is beyond the bite like vomiting and having trouble breathing.

Observe the affected area for 8 to 24 hours. If the redness and pain did not subside, you should seek help from your doctor immediately. It is recommended to bring the spider that bit you, even if it’s dead, to determine the best medication possible.

What Smell Does a Wolf Spider Hate?

Wolf spiders hate the scent of peppermint, cinnamon, tea tree, cedar, and citrus. Almost all of these are readily available in our homes. You can also buy these in the form of essential oils.

To get rid of the wolf spiders, mix at least five drops of peppermint oil, dishwashing liquid, and water. Put it in a spray bottle and spray it on areas where they usually are.

Can a Spider Fall to its Death?
