After Ettlich experiments with home remedies and supermarket baits, I have the desired success with this product. Had the bathroom repeatedly ants and with the gel they're gone. I also had a lot on the balcony, since the beasts had taken root in the flower pots. My trick. Take two empty Nespresso capsules, make a flat in a vice and then glue the other open. Drilling on the side about 5 small holes and inoculated the gel, ready is the effective ant bait, for flowerpots ;-)
