Problems
Prevention and Control : keep weeds down and utilise screening on window to keep them out . Remove or discard infested flora , keep them aside from non - infested industrial plant . Trap with white-livered gummy lineup or take advantage of born enemies such as predatory mites . Sometimes a serious steady shower of water will wash them off the plant life . confabulate your local garden center professional or county Cooperative extension place for legal chemical recommendations . Pest : Spider MitesSpider mitesare small , 8 legged , wanderer - similar creatures which flourish in red-hot , ironic weather condition ( like heated houses ) .

Fruit will be dwarfed and often drops early .
Prevention and Control : Plant resistant sort and space plant properly so they get adequate light and air circulation . Always water from below , keeping H2O off the foliation .
