Cockroach control
Why Cockroaches Keep Coming Back After You Spray
You see a cockroach, you spray it, and for a few days the kitchen feels clean again — until the next one appears at night. If this sounds familiar, you don't have a one-off visitor: you have a colony, and the spray is only reaching the few roaches you can see.
In Marbella's warm, humid climate, German and American cockroaches breed fast in the hidden spaces behind appliances, under sinks and inside wall cavities. Understanding why they return is the first step to actually getting rid of them.
The visible cockroaches are a fraction of the problem
For every cockroach you spot, dozens more are hidden in cracks, drains and warm voids near motors and pipes. A single egg case can hold up to 40 eggs, so a small problem becomes an infestation within weeks.
Supermarket sprays kill on contact, but they don't reach the harbourage points where the colony lives and breeds. You remove the symptom and leave the source untouched — which is exactly why they come back.
Why DIY sprays and foggers make it worse
Repeated spraying can scatter a colony, pushing roaches into new areas of your home and accelerating their spread. Many over-the-counter products also trigger resistance, so the survivors and their offspring become harder to treat.
Foggers coat surfaces but rarely penetrate the deep cracks where cockroaches shelter. The result is a lot of chemical, a lingering smell, and a colony that's still very much alive.
How professional cockroach control breaks the cycle
Our technicians start by identifying the species and tracing the harbourage points — under units, behind appliances, in drains and wall voids. We then apply professional insecticidal gels and targeted residual treatments exactly where the colony lives, so the active ingredient is carried back to the nest.
We finish with advice on sealing cracks, fixing leaks and removing the food and moisture that attract them. For severe cases we schedule a follow-up to confirm full elimination. See our cockroach control in Marbella for how the full process works.
