If you have suddenly found a line of ants marching across your kitchen or bathroom in the middle of January, you are not alone. This winter on the Costa del Sol has been particularly cold and wet, and that has sent emergency calls soaring in Málaga and Marbella.
What we are seeing is a survival phenomenon: ants are fleeing waterlogged soil and freezing temperatures. They are looking for the same thing we are: a dry, warm shelter with a pantry nearby.
Ants: a world of more than 22,000 species
We sometimes think all ants are the same, but nothing could be further from the truth. It is estimated that there are more than 22,000 species in the world (around 15,000 already described), and each has a fascinating survival strategy:
- Nomads: they have no fixed nest and are constantly on the move.
- “Farmers” of livestock: they herd aphids to obtain honeydew, defending them from other predators.
- Growers: they cultivate their own fungi underground for food.
This huge variety is why getting rid of them is sometimes simple and, at other times, a real logistical challenge.
Why do some disappear quickly while others seem invincible?
At RapiPlaga we always explain to our customers that success depends on the “size of the enemy”.
- The easy case: sometimes the problem is a small satellite nest in a flowerpot, a planter or a gap in the wall of the house. Here, with targeted professional treatment, the solution is quick and definitive.
- The challenge of supercolonies: this is where the most amazing science comes in. Some species, such as the Argentine ant (very common in our area), do not form simple nests but supercolonies.
Did you know…? Scientists have discovered a supercolony of Argentine ants stretching for 6,000 kilometres, from Italy to the Atlantic coast of Spain, along the whole of our Mediterranean coastline. Most incredibly, ants from this colony recognise each other as “family” and do not fight, even when they are thousands of kilometres apart.
When the enemy covers kilometres, the strategy changes
If the ant nest affecting your home or business is part of a network that stretches over hectares or square kilometres, treating just a few metres of your living room is like trying to empty the sea with a bucket. In these cases, wiping out the problem 100% for good is technically impossible.
This historical map shows how the Argentine ant forms huge supercolonies that stretch for thousands of kilometres along the coast of Spain. Because of this complex social structure, home remedies usually fail. Effective control of this pest requires professional help. If you notice this kind of invasion, contact the experts at RapiPlaga.
So what should we do?
- Strict hygiene: it is essential to remove any source of food. Not a crumb, not a drop of juice, no pet food left out. If there is no reward, they will look elsewhere.
- Control access: sealing cracks and entry points helps, although ants are experts at finding alternatives.
- Professional maintenance: when pest pressure is massive because of the surroundings, the solution is not a one-off treatment but a regular maintenance plan. The aim is no longer to wipe the species off the map (impossible with supercolonies), but to create a barrier and keep them at bay so your home remains clean and peaceful.
If the ants have decided to move in with you uninvited this winter, remember that understanding which species we are dealing with is the first step to winning the battle.
