ANSWER: Spider bites can itch.
More Info: Some spider bites have many of the same symptoms as a bite from any insect and include itching, redness, and swelling.
Spiders generally do not attack humans and spider bites are not common. Spiders have hollow fangs that are filled with venom which they use to kill their prey-usually insects. Many spiders are innocuous to humans and are not capable of biting because their fangs are too short or they are too weak to penetrate the skin.
Don’t Itch the Bite
Scratching the skin can introduce infection to any bite or skin lesion. Wash the area, keep it clean, and attempt not to scratch.
Stop the Itching
You can stop skin from itching by applying a soothing lotion such as hydrocortisone or calamine. Antihistamines may help the itching and alleviate any minor swelling. A cool icepack will generally provide some relief as well as taking a soothing oatmeal bath.
Symptoms of a More Serious Bite
Watch for any severe reactions such as intense pain at the site, fever, chills, vomiting, nausea, dizziness, light-headedness, and abdominal cramping. If you believe a venomous spider has bitten you, seek immediate medical attention. If possible, save the spider and bring it with you for identification.
