I've built a cold  Frame out of a box  with glass on top I put my runner beans  seeds in small pots inside  there is no bottom to the box but when I looked yesterday they was  hundreds of ants in there  but I moved it to another place on some earth ground when I look two day There was more  annts Will this kill the  plants or the seeds  how can I stop this ? Thanks

Check the ants haven't already got into the pots, you may have taken them to the new position that way.

I'd buy some Nippon ant bait and hopefully kill them all off.

I was going to suggest some puffs of ant powder, but Nippon would do the job too

You could also try Ant Bait Stations (pack of 2), the ants go in them and get ant killer on them and take it back to the nest and infect the rest of the colony. They're great, I use them in the poly tunnel and if there's a nest in a veggie bed. Outside I just put a bit of broken pot over them so they don't get too wet, then forget about it - no need to re-apply powder.

I Have ants in three or four places on my allotment and a nest in the compost bin. so not seen any reason not to keep them and the soil I got out of the compost bin was better than worm compost.
the robin likes the eggs when they get dug up. so I would think they are beneficial and not baddies.

They really aren't helpful if they take up residence in pots or trays of seedlings, though.

They also farm the Aphids and will attack Ladybirds to stop them eating the blackfly so a far from a best friend.
