Wasps
Social wasps, such as Vespula and Polistes, can sting multiple times, cause severe allergic reactions, and halt productive activities. Between 2011 and 2021, there were 788 deaths from hymenopteran stings in the U.S. (an average of 72 per year, 84% in males) cdc.gov. Fucesa removes nests with dry snow made of CO₂ at –78 °C, without chemical residues, and under an Integrated Pest Management (IPM) approach that complies with NOM-256.

Why act immediately?
Human health. Stings trigger intense pain and, in sensitive individuals, anaphylaxis; NIOSH recommends PPE and first aid protocols in risk areas cdc.gov.
Operational interruptions. Colonies of Vespula defend a radius of up to 400 m, which may force the closure of yards or production lines ipm.ucanr.edu.
Structural damage. Nests in roofs, walls, or electrical conduits promote leaks and short circuits australian.museum.
Repeated risk. Wasps are responsible for the highest percentage of deaths from arthropod poisoning in the U.S. ncbi.nlm.nih.gov.
Fucesa Method in 4 steps
Inspection and diagnosis
A technician entomologist locates the species and size of the nest; everything is recorded on the Cretia platform.Safe removal
We apply cryogenic CO₂ snow (–78 °C) that freezes the colony without leaving residues or generating resistance museumpests.netcryonite.com.Continuous prevention
We seal cracks, install screens, and place pheromone traps between the source and the area to protect, following university IPM guidelinesextension.usu.eduipm.ucanr.edu.Validation and reporting
We issue your NOM-256 certificate from Services with georeferenced photos.
How to recognize a nest?
Vespula germanica – Ground or wall cavities; traffic of workers at floor level.
Polistes exclamans – Open comb under eaves; visible cells.
Paper wasp – Gray nest on branches or railings; cardboard appearance.
Wasps help control other insects but become a pest when nesting near people ipm.ucanr.edu.
Benefits of choosing Fucesa

Frequently Asked Questions
What should I do if I am allergic?
Carry an epinephrine auto-injector and notify Fucesa; we follow NIOSH guidelines for immediate care cdc.gov.
Will the wasps return?
Colonies do not reuse the same nest, but new queens will occupy unsealed cavities ipm.ucanr.edu.
Is CO₂ safe for people?
Yes; it ventilates quickly and leaves no residues. Museums and archives use it to protect delicate items museumpests.net.
