Last summer I battled with wasps: this years it’s ants. Small black ones have underground nests in our yard, and they usually don’t bother us much. But a hot and dry summer recently inspired them to investigate our house, where they found two things they really like: sugar and water. When we returned from a trip to the archipelago, a busy ant highway stretched from the side door through a bedroom, a corridor, the dining room and into the kitchen, where the main destinations were our candy cupboard and the sink. Thousands of tiny insects.
I bought some insecticide. It looks like pale pink ice-cream sprinkles, and in fact consists mainly of sugar. But mixed into the sugar are two chemicals: one that makes the stuff taste awful to children and other large animals, and another that kills insects. It’s imidakloprid, a synthetic nicotine analog. I put a pinch of the stuff in each nest opening I could find out in the yard, and placed a small dish of it by the ants’ entry-point into our house.
It was frighteningly effective. After a couple of hours, that busy ant highway across our floor was gone. Our yard was also deserted. All that remained were a few dead ants. Apparently, most of them ran home when they started to feel sick. And none of them were of course smart enough to avoid the bait: they’d climb over the dead and dying to reach the stuff and gobble it up.
I love the smell of imidakloprid in the morning. It smells like… victory.
