    Default Ants, how serious a problem are they?

    Over the last week I've noticed small ants among my orchids. Drier weather has hit and I think they are after the residual water in the media and sap from the plants. I grow indoors so they are a nuisance but are they a more serious problem than that for my plants? Suggestions on getting rid of them?

    Thanks,
    Bob

    hi bob,.. i've dealt with ants. good thing they don't fly and have to go in and out of their nest (wherever it is not really important) mostly in line,.. what i do is i spray their pathways to the orchids with mosquito spray (repeat if they still could come, usually twice in 3 days is enough), not to the orchids, just the ground/wall/others where ants could pass from there,.. (move the orchids before you do it). that works for me,.. there is also chalk for ants (draw lines in which you don't want ants to pass that area), but it doesn't work to all ants. some ants could still pass the chalk,... i think making ants cannot pass is easier than treating the ants on the orchids.

    they could be nesting in your plants. if you fill your sink with water up to the top of the pot and sit the pot in the water slowly, see how many ants come rushing up. if there are a lot, they made a nest. we have invasive ants here in los angeles that are a huge problem for whole neighborhoods, as the ants do not fight each other and build thousands and millions of nests. they will get rid of termites, but other than they they are bad. they farm mealie bugs and aphids and who knows what else, passing virus sometimes. they can weaken a plant if infested with their herds and they usually go after the flower buds. i have used diatomaceous earth. it keeps them away from potted plants. it does leave a white long lasting residue... but if they keep coming back it will end it. for orchids i put a few spoonfuls in a jug of water and water the orchids once or twice a year, or if i find a nest.

    The ants in and of themselves will do no harm to your chids. The only issue for the plants is if the ants try to use them, as 'leo mentioned, to farm aphids or mealybugs. That is typically not an problem with indoor plants.

    The orchids i got fron broken tree had i think hundreds of ants crawling onto my hands and legs when i tried to break the log and all that. Ofcourse immediate reaction would be rinsing with water,... i think you've done that, if it's been a week. there are things i read on the net about chilly and garlic spray for ants on orchid. I tried this, it stinks but didnt work. Only tiny tiny bit. Did twice, but decided to stop. Not gonna wait too long to keep spraying once every 3 days as recommended, switched to that other method. All gone now, .. i think they are not coming back,..

    I use a little gel called Terro, you can find it at most stores (even grocery and drug stores). Cut a drinking straw into little 1" pieces. Squirt some Terro in it and then place it near their path. I think it's active ingredient is boric acid. It works really well for ants in the house.

    Thank you to everyone for the advice. Couple of days observation and haven't identified any pathways to/from my plants. Have used a combination of approaches... (1) diatomaceous earth and (2) liquid ant bait (Terro). Now wait and see.

    With the Terro, it will attract the ants. So, don't be shocked if you see more ants around the bait. They will eat it and take some back to the ant bed. Look it up on Amazon and read some of the reviews. It can take up to 7 -14 days of feeding to wipe out the colony.

    I have this problem not long time ago,all ants live in the orchid pot ant run out when I water the plant.i believe they have nest inside so I spray all the media(clay)with insect spray and rinse all the pot after that.all ants are gone and my plants still o.k....may be a bad idea but I do with caution..

    As quickly as they appeared they are gone. Three days and no sign of ants among the orchids. We've had rain over that period so maybe my plants are no longer as attractive with alternative water sources available.
