The size of the spider and the amount of venom injected. In most cases only a single drop is administered.
The part of the body where a person is bitten. A bite near the head is more dangerous than one administered on extremities.
The age and health of the person. Young children and ill persons may encounter greater problems.
The sensitivity of an individual to the venom. Just as some people are more sensitive to bee stings, the same holds also in respect of spiders.
The species of spider that administered the bite. The type of venom differs between species and it is therefore important to positively identify the spider so that the correct treatment can be given.
