Cockroach control
Cockroach Control in Lisbon & Leiria
Cockroaches are one of the most common pests and one of the hardest to get rid of for good. They breed quickly, hide in places you cannot reach and spread disease. At Desin Pragas we identify the type of cockroach, find where they are nesting and apply the treatment that suits the situation.

Questions
Questions about cockroaches
How do I know if I have a cockroach infestation?
The most common signs are: seeing cockroaches (especially at night), small dark marks (droppings) in corners and cupboards, a strong, sweet and unpleasant smell, shed skins and egg cases (oothecae).
Why do cockroaches come back after treatment?
When they come back, it is usually for one of these reasons: the treatment was incomplete (it did not reach the sources), generic products bought at the supermarket were used, new cockroaches came in from outside (neighbours, drains), or preventive measures were not followed. That is why we assess the problem before treating and give you advice after the service.
