Geckos
The family Gekkonidae belongs to the order Squamata. While not direct herbivores, geckos are frequently categorized as agricultural nuisances in greenhouse facilities. They do not consume plant tissues, but their presence disrupts sanitation standards essential for commercial produce.

Geckos
Geckos do not damage crops by feeding on them. The primary concern is the contamination of produce with fecal matter, which violates food safety regulations. For exporters of leafy greens and soft fruits, the sighting of a gecko can lead to the rejection of harvested batches, causing significant economic losses.
The biology of geckos within greenhouses is favored by high humidity and consistent temperatures. They are opportunistic predators that thrive where there is a steady supply of insects, such as aphids or fungus gnats. Their reproductive cycle in a controlled environment allows for rapid colonization of structural gaps and irrigation conduits.
The harm caused by these animals is mainly indirect. Beyond the sanitary risks, they can mechanically damage fragile stems or leaves during hunting. More critically, they act as vectors for pathogens, potentially spreading bacteria or fungal spores across different zones of the greenhouse facility on their feet and skin.
Protection and control measures focus on exclusion rather than eradication. It is crucial to seal ventilation ducts with fine mesh and patch structural cracks in the greenhouse frame. Since geckos rely on insect populations for food, maintaining a strict integrated pest management (IPM) program to reduce prey availability is the most sustainable way to deter them from the crop area.
