Which of the following is not advisable to do after a spider bite?

Attempting to remove the venom from a spider bite is not advisable because this action can lead to further complications, such as infection or deeper tissue damage. The venom has already entered the body, and trying to extract it may not effectively remove it but rather could worsen the situation.

In contrast, elevating the bite area helps reduce swelling and pain, while washing the affected area is critical to prevent infection and further irritation. Seeking medical help is vital, especially in cases where the spider is known to be venomous or if the bite shows signs of severe reaction. These actions are standard first aid measures that facilitate recovery and ensure appropriate treatment is administered when necessary.
