Ants in the greenhouse are not generally dangerous for all plants. However, if they appear in large numbers, courageous action by the allotment gardener is called for. Anyone who starts early with tried-and-tested home remedies can save chemical poisonous baits against the unpopular invaders.

Ants can usually be expelled from the greenhouse quite easily without chemicals

As annoying as they may be at first, it's still too superficial and even wrong to call ants in the greenhouse generally pests. They have many useful functions, for example disposing of dead insects, contributing to a good portion of useful biomass when building their nests and preferring to devour the larvae of leaf beetles and moth caterpillars, which are unpopular in gardens.

Simply relocate ant nests?

But still: You should do something against ants in the greenhouse as soon as possible and start at the lowest level, namely with the home remedies. A flower pot filled with excelsior, which is placed upside down near the ants' entry path, already helps in this case. A few days later, the ants and their larvae will settle there. The pot and its new residents must just shifted far enough now will.

Which ants aren't into at all

If insects perceive certain scents or particularly distinctive essential oils, they react relatively quickly with a trigger. Cinnamon has proven particularly effective for ants in the greenhouse, but the trick also works very reliably with the following home remedies:

  • chili powder
  • lemon peels
  • cloves as well
  • flowers of lavender

With targeted spreading or laying out, you create reliable barriers that ants usually avoid and do not frequent.

The fast ant trap for greenhouses

A mixture of stale beer and a little dash of honey placed in a bowl that is not too high, it almost magically attracts ants. You will quickly smell the almost irresistible scent to try to satisfy your sweet tooth. However, this project will end fatally for the animals, as they will drown in the liquid.

Chemical agents if nothing else helps

It would be illusory to render ants in the greenhouse 100% harmless using only natural means. If the destructive effect of the little beasts threatens to get out of hand, only ant poison really helps. It is effective enough to eradicate the ant colony and its queen quickly and completely. Still must aware of such chemicals and handled in moderation, since the crops in the greenhouse are contaminated with these toxins, although they are not inedible.

tips

Check whether ants are beginning to settle in the greenhouse, especially in humid and warm temperatures. The animals can usually be seen first, preferably below the leaves of plants. However, larvae also like to hide in the upper soil layers.
