The ants themselves are not a threat to lawns in the UK. Instead, it’s their humble abodes that turn perfectly flat terrain into bumpy patches. Ant mounds create unsustainable areas of grass that should be removed immediately. Unfortunately, too many homeowners prefer to pour boiling water into the mounds, which only results in dead patches of lawn plants.
We have a better idea of how to deal with ants.
Ants provide protection against aphids…and it’s not good
In the UK, black ants like to eat sweet foods. Workaholic insects are particularly fond of honeydew, a secretion generated by aphids such as aphids, whiteflies and black flies. Ants protect aphids from attacks by predators such as ladybugs. While that sounds like a good thing, the fact is that more aphids in your lawn will cause more damage to your lawn and plants. If you discover black ants on plants, flowers and vegetables, be aware that black ants protect predatory insects that consume the sap.
How to eliminate ant colonies
In dry weather, eliminate anthills by spreading the earth dug by the ants before mowing the lawn. A broom or stiff garden broom should effectively spread the debris from the anthill across the lawn. If your lawn has uneven surfaces due to the presence of anthills, re-turf the raised areas of your lawn and remove the excess soil. This procedure is most effective in winter, when ant colonies are often dormant. Be sure to place the mower in a higher mowing position to avoid cutting debris from the mound.
Prevention is the answer
Responding to an ant problem can only provide temporary relief; Preventing ants in your lawn is the most effective long-term solution. Consider purchasing baits, sprays, powder and/or sprays to prevent ant migration into your lawn. UK homeowners can find products available at local garden centers or DIY stores. You can also use the pathogenic nematode, Steinernemafeltiae, which some mail-order sellers offer online to treat ant nests that form in lawns and in plant and flower beds. Many professional gardeners use Steinernemafeltiae as a last resort to get rid of pesky black ants.
If you think ants have invaded your once healthy lawn and garden to the point of overwhelming them, consider hiring a professional who has the tools and experience to restore your lawn to its former vibrant look. .
