Since 1991 I have been embroiled in a low-intensity war. Battles are limited to the summer months and are, for the most part, conducted underground and therefore well-concealed. Battles are fought on the set of seventeen steps which allow us to safely descend the steep, gently winding slope between our summer cottage and the lower meadow which extends to the lakeside.
The steps were cut into the hard, dry clay of the slope many years ago, following the gradient and winding nature of the land. No two steps are the same; some are short and steep, others long and shallow. Thick wooden planks held in place with rough metal bars hammered into the clay mark the edge of the steps, which are covered with a layer of natural gravel. Normal, wet summers the loose gravel is held in place by a carpet of tough weeds which force their way up through the heavy clay. Grasses, clover, dandelions and other weeds here actually have a useful function. In a dry summer with few weeds to anchor the gravel, striding down the steps is an altogether more treacherous enterprise. Not to speak of running down.
Exactly where the enemy decides to strike is a mystery. Most of the time the war is an underground operation. One year the battle may be concentrated to the fourth step, another year step number ten. This year the battle was fought on, or rather under number twelve.
The give-away sign that this summer’s battle had kicked off was the appearance of small piles of fine dust where the plank sticks up from the clay. The one sure way of corroborating this is a gentle kick to the top of the plank. If it moves, we are in trouble. If it comes loose, the damage is so serious that the battle is already lost. Undisputable proof is the characteristic hacker damage in the remains of the plank. Clear evidence that the enemy has won this year’s battle.
Yes, you guessed! Ants – the usual culprits. Sometimes red, sometimes black, sometimes small, other times large, but always lots of them hacking and munching away at the wooden planks shoring up my steps.
Most years I have to replace one plank, but some years two separate armies of ants decide to invade the steps.
What can I do about it? My choice of weapons is limited. What about ABC-warfare? So far I have tried biological weaponry – pouring large quantities of water on the steps. Ants prefer dry ground but just shook the water off and carried on the battle. A chemical weapon, sprinkling MYRR under and round the planks, was more successful but only in the short term. Long-term use and increased doses proved financially prohibitive as the ants just moved on to another plank. Hacker warfare is subject to some budget restraints.
I even considered asking the local hospital for surplus or out-of-date isotopes, but decided against it; radioactivity could lead to mutations and, in the long run, giant warrior ants.
So I am reduced to pursuing a low-grade guerrilla strategy. First, by not replacing planks until all the ants have moved on. So far I have been replacing damaged planks with new timber as soon as possible. I call this strategy “Starve the Brutes”. Second, investment in the latest generation of impregnated timber technology, designed for use in the ground or in water. Thicker, heavy duty, more potent . This strategy is designed to directly affect the hacking of the ants so that it takes them longer to masticate the wood fibres. Hopefully they become weaker and finally decide to leave for greener pastures. Combined with the chemical approach this could just tip the balance.
The end result appears solid enough, but appearances are deceptive. Already after one day I noticed the red forest ants had sent a couple of scouts to check out my latest attempt at winning the war. I managed to exterminate the scouts, but have no illusions. They will be back!
What next? I still have a few things up my sleeve. For example replacing the wooden planks with hardwood, metal plates, stone slabs or artificial composite wood, not to speak of a massive reinforced concrete staircase. Less charming, I know, but battles are there to be won. All’s fair in love and war!
