Roaming Red Spider Mite

Many thanks for your enquiry regarding red spider mite. It appears that the creatures creeping around your path and back door are not the greenhouse red spider mite which the phytoseilius persimilis predatory mites control. 

The greenhouse red spider mites are actually yellowish green in colour with a pair of darker markings, and only develop an orange red colour during the autumn-winter resting period. The breed extremely quickly in warm weather and feed by sucking sap from plants, creating webbing between leaves, a sure indication of their presence in the greenhouse. 

Although we are aware of the creatures you have on your path, our knowledge does not extend to any biological control which exists.  Hopefully this information is of help and please accept our apologies for not being of further assistance on this occasion. 

Many thanks once again for your enquiry.
