Pest Status

Can invade homes much to the horror of spider haters because of size and hairy appearance. Bites occur rarely and no known causes of fatalities exist. Some species are know to inflict a painful bite that may result in local discolouration and swelling, dizziness, vomiting, lethargy, irregular pulse, persistent nausea, sweating and a welt at the bite site. In young children the effects can be more exaggerated. The possibility of bacterial infection should be considered when treating any bite. Insufficient information exists on the toxicity of these spiders to state whether they are entirely harmless. Should be considered as useful because it feeds on other insects
