Life in tropical north Queensland is revealing itself in a variety of ways not least the multitude of tiny ants that invade our house on a daily basis. They find tiny juice splashes that missed being mopped, crumbs that didn't get swept up, they invade my friend's iron of all places but the most disturbing is the invasion of my knickers in our laundry bag (not dh's, no ants at all in either ds laundry bag) - they are actually making holes in them - what can I do? Are there products I can use to prevent/kill them safely with the boys around?
