Spider bites

Spider bites

An injury ensuing bites of spiders is spider bite. Spiders bite as a mode of defense; they paralyze or kill their prey with their bites before devouring them. They generally do not attack creatures bigger than them but some of them are so aggressive that they need little provocation to attack. Most of them try running away from larger organism or feign death to avoid confrontation with them. A huge percentage of the spider bites are harmless, but there are quite a few which are dangerous; there can cause death in some cases. Spiders can be venomous or non-venomous; bites caused by venomous spiders last more than 24 hours whereas bites by non-venomous spiders last only for 5 to 60 minutes.

Consequences of spider bites

One of the prime concerns with spider bites is their venom. They inject the venom through the skin, but not all spiders can penetrate through human skin. Most of the spider bites are not serious for humans but sometimes the infections caused by them might be. When spiders eat their prey there is a possibility of bacterial attack which percolates to the humans when bitten. The amount of venom they transfer also depends on their species and the encounter. Spider bites are either neurotoxic which means it would effect the nervous system or necrotic which attacks the tissues surrounding the bite and in some cases they might affect the vital organs.

A majority of spider bites are harmless and may not need any treatment. In some cases their effect is observed much later than the actual bite and may be a cause for concern if not observed at the right moment. For a normal spider bite washing with soap and water would be enough. Applying ice is another option, but for severe bites antibiotics are needed for further precautions.
