Ants in planted pots ok?
I have a large olive in a pot in my patio garden and it has grown very well,
however I notice in the last few days that ants are entering the pot from the bottom and taking soil out (only small amounts). Are they living in it? Will it hurt the plant? I have tried moving the olive but they seem to follow it around! Any advice? Mike |

Mike If the ants form a colony in the pot it certainly will be detrimental to the plant so I would deter them by standing the pot in water for a short while and this will cause the ants to disperse. Then place the pot in an ant free spot and hopefully all will be well. Regards, Emrys Davies. |

Your solution is the correct one for the former case, of course. Regards, Nick Maclaren. |

Mike,
Just found this more sophisticated method of ant control. You may think that it has merit. http://www.pan-uk.org/pestnews/homepest/ants.htm Regards, Emrys Davies. |

Ants in planted pots ok?
g'day mike,
no is the answer they can cause all sort of problems and bring their symbiotic bugs in as well. the best way is to stand the pots in water up the the brim for around 24 hours to flood the nest, keep the water up to the brim but not over for that period. then have trays under the pot that will hold water and using those specila pot stands or pieces of tile etc.,. to use to hold the pot above that water level that will keep them out so long as none of the foliage touches anything that the ants can use to climb back into the pot. len On Thu, 24 May 2007 06:55:07 GMT, "Mike" wrote: snipped With peace and brightest of blessings, len & bev -- "Be Content With What You Have And May You Find Serenity and Tranquillity In A World That You May Not Understand." http://www.lensgarden.com.au/ |

All of the references I have seen, and my observation over many years, indicate that is at best an urban myth. More bluntly, it is just plain wrong. I don't know whether there are any 'farming' ant species in the UK - most references are evasive on that - but Lasius niger is not one of them. It does do some desultory herding, but that is about all. I have seen one decent reference that indicates that it may assist aphids, but the research had a fair number of possible flaws, and it was done so long ago that I couldn't check with the author. It is vanishingly unlikely that Lasius niger will import aphids onto plants in posts that they are nesting in. Regards, Nick Maclaren. |

I have seen one decent reference that indicates that it may assist aphids, but the research had a fair number of possible flaws, and it was done so long ago that I couldn't check with the author. The best first hand evidence I have of UK black ants doing more than exploit existing aphids is the earth castles they sometimes build to protect them from overheating: http://sprouting.org/temp/ants/ ....has photos. I have now seen these things built six inches high. When the growing point is too high off the ground, for a tower to reach, the ants can still carry moist earth up and stick it on around the target area. http://cat.inist.fr/?aModele=afficheN&cpsidt=15221511 ....has Lasius niger excluding predators from aphid colonies: ``Large predators were excluded by both ant species from the aphid colonies, while they were abundant in ant-excluded colonies.'' http://jeb.biologists.org/cgi/content/abstract/35/4/703 ....has Lasius niger sucking twice as much juice out of beans when attended by ants. ....and this looks pretty conclusive to me: http://www.brown.edu/Departments/EEB...00_ecology.pdf ``The presence of workers of the ant Lasius niger had a strong positive effect on the fitness of individuals of the aphid Metopeurum fuscoviride. Ant-tended individuals lived longer, matured earlier, had a higher rate of re-production, and a higher expected number of offspring than aphids not tended by ants. An aphid’s longevity was significantly correlated with the daily mean number of workers tending it.'' -- __________ |im |yler http://timtyler.org/ Remove lock to reply. |

The aphids bite into the plant and lock on, there is then a continuous flow of honey dew from their rear end, the ant take advantage of this free food fountain! If the flow stops they tickle the ant's rear end to get it going pk |

I've never had any real problems with ants in pots or any other part of the garden, they are a right pain when they get into the house though! In what way, Alan? I lived in an old house that had them all over the place. The most fascinating thing I've ever watched was two 'tribes' fighting. Each tribe was the size of a large soup plate and they were in the middle of the dining room floor. But if I kept all food covered securely or sealed, they did us no harm. -- Sacha http://www.hillhousenursery.co.uk (remove weeds from address) |
