They are not always visible, so it is important to learn how to detect a hidden wasp nest before it becomes a real health problem for your family or your business customers. If you live in Cartagena or manage a venue in the Mar Menor area (La Manga, Los Alcázares, San Javier...), you will know that our climate is enviable, but it is also a paradise for certain insects.
Of all of them, wasps are probably the most unwanted and dangerous guests. We are not talking about seeing a solitary wasp flying near the pool or a plant. We are talking about when the problem is inside, latent and growing without you realizing it.
As pest control experts in Cartagena, this year we are noticing a worrying trend that we want to share with you: wasp nests are no longer just in the visible corners of windows. Now they hide where you least expect them.

Many people call us scared with the same description: "I hear a constant noise in the living room, like an electric buzz, but I don't see anything". That sound is usually the first and only alarm signal.


That is the most dangerous scenario. Wasps look for places protected from the wind and direct sun to breed safely. Plaster false ceilings, roller shutter boxes, or air conditioning gaps are five-star hotels for them. They enter through a tiny crack in the facade or a shifted roof tile and build the nest in the dark.

What is the real risk here? The problem with a wasp nest in the false ceiling is that, over time, the nest grows and becomes heavy. The ceiling material can give way or, worse yet, the wasps can find a way into the interior of the home through the holes of the halogen spotlights or ventilation grilles. Suddenly, you have the swarm inside the house.
We often underestimate the danger of a sting until the accident happens. Unlike bees, wasps do not lose their stinger when stinging; this means that a single specimen can sting you several times in a row, injecting venom with each attack.
In our area, with the influx of tourism and full terraces, the presence of wasps is a serious risk that we must control:
It is tempting to go to the supermarket, buy a spray, and spray it bravely. But if the wasp nest is hidden (false ceiling, air chamber), the spray will never reach the core of the nest.
The only thing you will achieve with this action is killing the few that are patrolling outside, angering the hundreds that are protected inside, and causing them to look for another exit... which will probably be towards the interior of your living room or bedroom.
In pest control, safety comes first. To eliminate wasps in Cartagena and the Mar Menor, you not only have to have the appropriate protective equipment (PPE), but know which biocide to use and how to apply it so that it reaches the heart of the wasp nest without causing an uncontrolled stampede.
We locate the exact entrance, treat the nest locally, and seal the problem to prevent recurrence. All this without construction work, without drama, and without putting you or your clients in danger.


Do you have suspicions? If you see a constant traffic of wasps entering and leaving through the same point of your facade, or hear that buzzing in the ceiling, do not wait for them to break through.
