white flies on hibiscus inside house
I have a couple of Hibiscus in self watering pots that i keep behind the
patio window which is south facing. they had a lot of tiny white flies and i was told to spray with a mixture of water and dish washing liquid, which i did. but about three days later they are now back again with a vengence. i dont know where they have all come from suddenly. i would prefer not to use chemicals to stop the white fly since i keep the plants inside. any other suggestions please? |

They're probably the offspring of the generation you killed. Spray again with slightly soapy water. Other possibilities: 1) yellow sticky flypapers - the whiteflies are attracted to the colour. Will reduce but not eliminate 2) Biological control - predators for whitefly are available on-line. You wouldn't be able to continue to use the soapy water as it would kill the predator too 3) Take the plants outside and give them a good shake each time the population builds up 4) Vacuum clean using the upholstery brush -- Kay |

This isn't necessarily a problem any other suggestions please? There are two types of insecticide. Contact insecticides - which you spray once and it will kill all the insects it comes into contact with, and systemics which are absorbed by the plant tissue and kill any insects which try to eat the plant. Systemics are more expensive and of no extra benefit in this situation. Regardless of their effectiveness. To use a contact insecticide on houseplants take all the plants outside into the garden and give then all a thorough drenching from all angles with a contact insecticide. That includes from below, especially the undersides of the leaves, because aphids are adept at hiding from natural predators such as birds. This has to be thorough, something you can't do indoors as you appreciate, when there's an danger of getting stuff on the curtains or upholstery. Then, when you think you've given them all a thorough drenching, just to be sure, do it all over again. You can make up your own using dilute washing up-liquid, but this is mainly for people who use it in the greenhouse ot garden where they use gallons of the stuff in the course of a year, and where they don't want to kill off any beneficial insects. Neither of which apply with plants kept indoors. The shop bought stuff is guaranteed to do the job providing you use the right dilution, and are sufficiently thorough. michael adams .... |

Put them outside during the next period of rain. It may not clear the infestation completely, but it should reduce it. -- Stewart Robert Hinsley |
