| Assuming there is no water ban, you can water the lawn to stop it drying too much. The ants are probably mating in this weather. are thetre jackdaws and other birds viewing them from nearby trees? After the weather changes for the cooler they will stop swarming. There is a poison you can or could get for them. Borax in syrup I think it is. Your local garden centre will put you right. Whatever, don't fret overmuch just yet. |
