All spiders are venomous, but most are not considered to be harmful to humans. However, Kenya does have quite a few spiders that can cause some real harm to animals and humans if bitten.
Funnel-web Spider
SEEK MEDICAL ATTENTION IMMEDIATELY IF BITTEN
Apply a pressure immobilisation bandage to the bite site and the adjacent limb. For example, a bite on the finger should be treated by bandaging the entire arm. Further restrict movement by applying a splint.
Sac spider
(Chieracanthium)
WATCH AND ACT
Do not cut the area of the bite as this can lead to the spread of the venom and lead to infection. Use antibacterial cream to ensure infection doesn’t take place. If there is however, seek medical attention.
Button spider (Widow spider)
SEEK MEDICAL ATTENTION IMMEDIATELY IF BITTEN
If it is possible, keep the spider, even if it is dead to help determine the appropriate treatment. Seek medical attention as soon as possible and keep the person or affected area as motionless as possible. Avoid eating or drinking, loosen tight clothing and apply ice to the affected area. Also keep feet elevated.
Violin spider (Recluse spider)
(Loxoceles)
WATCH AND ACT
Watch the affected area with cool water and mild soap, and be sure to elevate the area and apply ice to reduce pain and swelling. If conditions worsen, please consult a doctor.
Black House Spider
WATCH AND ACT
Local swelling and pain can sometimes occur from a bite, including nausea, vomiting, sweating, muscular pain, headache and dizziness, but these are very rare. In a few cases skin lesions, necrotising arachnidism have been recorded after bites. A cold pack may relieve local pain. Seek medical attention if symptoms persist.
Golden Orb or Orb Weaver Spider
WATCH AND ACT
Not usually harmful to humans. Mild local pain, numbness and swelling can occur from a bite, including nausea and dizziness. Seek medical attention if symptoms persist.
