If you find you have ants in your flower bed it should be pretty easy and straight forward to get rid of them. There are a few different ways you can go about this but some options are better and safer than others are.
There are many insecticides on the market that can take care of an ant problem. Some are generally safe and others can be quite toxic. When an ant comes in contact with an insecticide and then grooms himself, he will then ingest the poison and die.
Another option is to use a dust. This will work best if you are not using the dust in a very wet environment where it can quickly dissolve. EcoSMART has some very safe dusts available if you choose to go this route.
The safest and most effective way to get rid of ants in flower beds is by using bait, but first you want to discover what the ants are eating. Most ants will eat proteins or sweets. If the ants are in your flower bed it is most likely they are looking for sweets and are feeding on the pollen.
Knowing this you can pick up a sugar or sweet based bait. The worker ants will not eat the bait themselves but will take it back to the colony and feed it to the larvae. The larvae act as the food factory for the colony. The adults and queen feed on the byproduct of larvae. In this way, you are killing ants in all stages at once with one effective product.
We also recommend a bait called Niban. Niban is Boric Acid based. Boric Acid is very safe with a toxicity level which is half that of table salt. It is a granular made up of protein and carbs along with the Boric Acid. An added benefit to using this bait is that it will also take care of other garden pests such as snails and slugs. The beneficial insects in your garden such as lady bugs will not be affected by this bait.
