Have already had a 250g & 500g pack the product. In the garden I was dealing with some ant nests. Between paving stones, on the lawn and also partially on the beds. That means I have scattered in front / in the nest entrances and the next day true peace. In individual cases, after only 10-12 hours. Is probably at it, how big is the nest. On the beds, please be careful, just near to eat. On the lawn, please make sure to remove the latest after two days the granulate remains. Since the grass otherwise being damaged !! The paving slabs, with no problems. The funds earned in my view, clearly the 5-star. >> Strong buy recommendation
