Here are a few things that leaf-cutter ants seem to like (and thus, if you have an ant-infested lot, you may wish to learn from my costly experience):
- Roses. They can devour a rosebush in a matter of hours.
- Scorpion tails. I actually don't know what these are really called in English; I'm translating from Spanish here. Hummingbirds and butterflies love them; so do leaf-cutter ants.
- Hydrangeas. Forget it.
- Gerbera daisies. They even take the petals off all of the flowers.
- Orchid trees (buy a big one and it should be okay; they keep eating the leaves off of my little one every time it tries to come back).
- Pomegranate trees (same suggestion as above).
- Canna lilies.
- Raspberry canes.
- Bird of paradise flowers. Mostly the leaves, thus not actually giving the flower itself a chance to, well, flower.
- Butterfly weed.
- Most herbs, including parsley, lavender, and basil.
- Not much else.
The ants are so-so on passionflower/maracuya/passaflora so far. Sometimes they cut them down, sometimes they don't. I think if they have better plants to destroy, such as my beautiful roses or scorpion tail plants, they'll leave the passafloras alone.
Well, today I put all of my roses in pots, so let's see how they do.
And just for fun, here are some pics of leaf-cutter ants doing what they do best:
