Why do I have field ants?
Field ants, also called mound ants or thatching ants, build outdoor nests, constructing mounds in the soil anywhere in the lawn or yard. Some species prefer to live under firewood piles, bricks, lawn ornaments, trees, and rocks.
The ants feed on the honeydew produced by aphids and other plant-sucking insects, as well as sugary substances, soft-bodied insects, seed husks, and dead insects.
How worried should I be about field ants?
Field ants rarely come indoors, but in the yard, their mounds may prevent the growth of grass or surrounding plants and can cause problems when the lawn must be mowed. Mounds built by field ants can grow as large as 30 cm in diameter and so can create an unsightly scene.
While field ants do not bite or sting, they can pinch human skin with their mouthparts, expelling formic acid to give a stinging or burning sensation.
Fields ants are difficult to spot early on, before the mound is fully formed, but once established a single field ant colony is capable of surviving a decade. If you do decide they are a nuisance, the best way to eliminate them is with the help of professional pest control services.
How can I prevent field ants invading?
Check under wood piles, lawn ornaments, and large rocks, Locate and fix any cracks in the foundation, Repair broken screens on windows and doors, Check that drainage is free-flowing and clean, Trim back overhanging shrubs and trees, Keep lawns clear of clutter and debris
