Ants and cockroaches pose a critical challenge in the hygienic and sanitary management of civil environments and food production facilities. Ants, thanks to their highly organized social structure, are able to successfully nest both inside and outside buildings. Cockroaches, on the other hand, are known for their ability to hide in cracks within warm and humid areas, where they can develop rapidly.
Globalization has facilitated the accidental introduction of invasive alien ants, originating mainly from South America and Southeast Asia. Among these, one of the most problematic species in Europe is the ghost ant (Tapinoma magnum), often at first glance mistaken for our native garden ant (Lasius niger).
Unlike this native species, Tapinoma magnum can form supercolonies with thousands of queens and millions of workers, extending over large areas of up to one hectare.
To control a colony of this scale, it is essential to accurately map the infested area and implement an integrated control program, based on a thorough preliminary environmental assessment followed by targeted treatments.

Effectively eliminating an ant infestation requires a technical approach, structured according to the area to be treated—indoor or outdoor—and the level of infestation.
For disinfestation treatments, the following can be used:
Insecticidal gel baits such as Advion Ant Gel and Outcast Ants. Advion® Ant Gel is an insecticide based on Indoxacarb, an active ingredient with delayed action that allows worker ants to transfer the insecticide to other members of the colony through the mechanism of trophallaxis—food sharing—thus enabling eradication of the nest.
Granular insecticidal baits such as Nexa Granular Ant Bait, which works with the same mode of action as gel baits but can be more easily applied in outdoor environments such as lawns and gardens.
Liquid insecticides for indoor use (e.g., Fendona PRO, Cymina Ultra) or for outdoor interventions (e.g., Cymina Plus, Flytrin 6.14, Sting RTU), with immediate efficacy against visible individuals.
A thorough inspection of the environment is essential to identify ant trails, or pheromone paths—chemical tracks laid by worker ants to search for food and return to the nest.
Ants can nest:
in cracks in walls and floors;
near doors, windows, and conduits;
close to food sources (kitchens, pantries, canteens).
Incorrect application or overly aggressive treatment can cause the colony to fragment into multiple nests, making control more difficult.

Cockroaches, particularly species such as Blattella germanica, Periplaneta americana, and Blatta orientalis, are distinguished by their extraordinary ability to adapt to human environments. They live in hidden places such as cracks, cavities, food equipment, basements, false ceilings, or cable ducts, where humidity and warmth favor their proliferation.
Timely intervention against cockroaches is essential to prevent a localized infestation from turning into a structural problem.
The presence of adult specimens, droppings, oothecae (egg cases), or a persistent unpleasant odor are clear signs of an established infestation requiring immediate professional treatment.
Industrial kitchens, canteens, warehouses, and food companies are high-risk environments where infestations can escalate rapidly. In such cases, it is strategic to adopt a prevention and monitoring plan, with targeted interventions to address defined critical thresholds.
