Last year at this time, I had a problem with ants in my apartment. Most of the time, they do not bother me overly much. I find the odd scout reconnoitring my rooms, the random forager exploring to see what food he may find to bring back to the colony. They are of a specific species and appear singly.
More annoying is the other species, the denizens of a colony that decide to launch their winged youngsters on their way to found new ant-nations. They too are usually not troublesome, but at this time of year, they choose the wall of my sitting room to break through and shoot off their pioneers.
I have tried various remedies for this invasion. Anything powdery does not work because the ants simply crawl along the wall, or the hot-water pipes that run beside it, until they they beyond the powdery barrier. Ant-traps are worthless. I have put down several, of different varieties; if the poison within is taken home, then it obviously is not destroying enough insects to matter. Orange oil seems to deter them a little but not sufficiently.
I am now using vinegar as a principal weapon. I spray it, diluted somewhat with water, on the part of the wall by which the intruders come, and pour some drops on the exact spot that seems to be their main entry. This has slowed their actions, so I prepared a vinegar-bomb: a small rag soaked in the sour substance and pushed as close to their entrance as possible. This has been the most powerful deterrent so far, though even it is not entirely effective. I renew the warhead of the bomb (soak it in more vinegar) every couple of days.
The solution is for the hole - for such it seems to be - through which the ants enter to be sealed. This will take a visit from the building manager and possibly some minor dismantling of pipe-coverings, so it can wait for now.
At least this year’s intrusion is not as bad as last year’s, and I have not yet had to flood my apartment with a spate of river-water, the way Charlton Heston did in The Naked Jungle. This is good, as we’ve had very little rain and the local river is low and sluggish…
