Pest Control



    • Investigation of complaints relating to pests


    • Treatment of infestation by insects


    • Treatment of premises for rodents


    • Disinfection of premises in respect of infectious diseases


    • Disinfection of articles in respect of infectious diseases


    • Laboratory Identification of insect pests


Pests such as cockroaches, rats, mice and fleas are found in all societies and know no boundaries. The Agency’s Pest Control Operatives are dedicated to their control and use the latest environmentally friendly pesticides and techniques to exterminate them when found. Great care is taken to ensure that only the intended species is exposed to the pesticide. When poison bait for rodents is used, tamper proof containers designed to prevent access to it by non-target species such as dogs, cats or birds are used. The main sewer system is continuously being treated for rodents as part of an ongoing program and other areas are treated as the need arises.

During the warm spring months it is sometimes necessary to carry out an anti-mosquito campaign to reduce their populations. This requires a slow systemic search through an area looking for bodies or containers of stagnant fresh water which may be allowing the mosquito larvae to breed. Contrary to popular believe they do not breed in refuse or sewage and since they can fly about 2km in still air a breeding site at one end of town may affect persons at the other end.

Common household pests found locally

Periplaneta Americana:    American Cockroach usually associated with sewers and drains and damp dark undisturbed environments. Do not live in domestic premises but may enter when their normal habitat is disturbed.
Blatta Orientalis:    Oriental Cockroach usually found in old wooden floors and old buildings. Not very common locally.
Blatella Germanica:    German Cockroach or Steam Fly common in kitchens.
Calliphoria Vomitoria:    Blue bottle blow fly.
Musca Domestica:    common house fly.
Culex Pipiens:    blood sucking mosquitoes found locally. Only the female bites.
Ctenocephalides felis:    Flea – blood sucking
Cinex lectularius:     Bed Bug – blood sucking

Rodents found locally which would require pest control measures to be adopted:

Mus Domesticus:    house mouse
Rattus Norvegicus:    brown or sewer rat
Rattus Rattus:    black or ship rat

The control is firstly exclusion by various rodent proofing techniques in buildings and premises, and secondly elimination by the use of traps or poisons. This is carried out only by trained operatives.

The agency only carries out pest control treatments in Her Majesty’s Government of Gibraltar premises.

The Agency is not responsible for the culling of animals and birds. However the Agency organizes and supervises pigeon culls conducted by a third party as part of the Avian Flu Control Strategy of Her Majesty’s Government of Gibraltar’s Civil Contingency Committee.

Bees and Wasps

These are not pests under the public health definition but nevertheless can cause distress and concern in some situations. It is common in late Spring for bees and wasps to swarm which can be intimidating as they can set up a temporary camp somewhere nearby, such as a tree branch, fence post and even on cars and motorbikes. In almost all cases the swarm will take off again within a day or two to occupy a most suitable permanent home elsewhere. Bees are a valuable insect and are endangered so we’d always recommend exploring all other avenues before considering eradication. Below is a step by step guide to assist you:

  • Leave them alone – Bees don’t cause any problems to your property, and nor are you in danger of being stung if they are left alone and unprovoked. After the summer season the bees will go away and not return to the nesting site the following year. Therefore if at all possible always leave bees nests alone to thrive as their presence is actually beneficial for gardeners and their crop.

  • Relocation – If a bees nest is outside or underground then there shouldn’t be a reason to really move it. In more conventional and accessible places such as bushes, trees and sheds, then we will try to relocate the nest. Only if the location of a nest is dangerous and removal not possible, should the next step be an option. Wasps due to their aggressive nature are difficult to relocate.

  • Eradication – Only considered as a last resort and must be done by a trained professional pest controllers.
