How much does a professional mosquito pest control cost and how does it work?

Preparation of professional mosquito pest control intervention

To defend yourself against mosquitoes, you need a thorough knowledge of the habits and biological cycle of these insects.

In Italy, in fact, several species of mosquitoes live. Some such as the tiger mosquito are particularly adapted to the urban environment and are also active during the day, others have nocturnal habits and are linked to natural or rural environments.

Larvicidal interventions

As we have seen, the life of mosquitoes is indissolubly linked to the presence of water, where they lay the eggs that will hatch to give life to the larvae and later to the real adults.

In the case of an intervention by a professional company, the inspection phase is therefore fundamental to develop a correct mosquito control plan and should aim at mapping all the mosquito developmental hotbeds on which it is possible to intervene (drains, saucers, etc.).

In limited environments the identification of outbreaks is certainly easier, although it should always be considered that the presence of mosquitoes in a given place can certainly be influenced by environmental situations in neighbouring places.

In very large areas it may be appropriate to apply a large-scale insect monitoring plan in order to obtain useful data to identify the most frequent outbreaks.

Larvicidal interventions allow a large number of potential adult mosquitoes to be eliminated in a short time and are essential as part of a mosquito control plan.

Some municipalities oblige citizens, businesses and condominium administrations to plan and implement appropriate anti-parasite interventions to reduce the presence of mosquitoes in order to preserve public hygiene.

See Ordinance of the Municipality of Rome for example.

It is important to always require the professional operator to carry out an inspection before performing an intervention.

Adulticide interventions

This professional fighting method, by far the most widespread in Italy, aims to eliminate adult mosquitoes present in the environment.

This technique involves the use of insecticides with abatement and residual action. The frequency of intervention should be defined after evaluating which species of mosquito is causing damage or annoyance to the population.

In practice this is not always possible and in fact professional companies tend to set up a defence plan that foresees the execution of treatments at close intervals, normally twenty days.

Professional companies, before carrying out an intervention, are in most cases obliged to give notices sufficiently in advance so that all those directly or indirectly involved (residents in the surrounding areas) can take the right precautions to avoid problems of ecotoxicity and toxicity to people and animals.

Specifically:

  1. Remove or cover plants intended for human or animal consumption
  2. Protect pets from direct contact with the insecticide (dogs, cats, birds, etc.).
  3. Close all doors, windows and vents
  4. Shelter children’s toys, water tanks, animal bowls, animal kennels, bird cages etc..
  5. Remove cloths or clothes lying down, pillows, etc.
  6. Do not stay in the affected areas during interventions.

The professional operator, however, must always check that all possible precautions have been correctly implemented before starting an intervention and warn his managers, or those directly involved, if he detects risks to the safety of animals or people.

Methods of professional mosquito pest control intervention

Larvicidal interventions

Since all mosquitoes need a certain amount of water to lay their eggs, the professional pest control company will first propose to perform specific interventions against larval stages and evaluate the possible mechanical removal of stagnation.

For example, abandoned containers and bins, tyres, disused but not emptied swimming pools, obstructed gutters, under racking, etc… or the installation of manhole and drain protection systems (mosquito nets, tilting systems, etc…) to prevent the oviposition of mosquitoes.

Larvicidal interventions can be carried out with products of different types both in terms of action mechanism and environmental impact.

There are natural larvicides, such as Bacillus thuringensis, chemical larvicides that block the development of larvae, and substances with mechanical action that form a very thin biofilm on the surface of the water preventing the larvae from breathing.

In general, larvicidal treatments are those with the lowest environmental impact and no special precautions are necessary during the course of treatment as toxicity to vertebrate animals and humans is practically non-existent, and also for this reason it is possible to perform them indifferently throughout the day.

The interventions must always be repeated with a certain frequency, depending on the product used, and cover the entire period of development of mosquito larvae, which varies from March to October.

Adulticide interventions

Adulticidal interventions are carried out by distributing insecticidal products in all those areas where the presence of mosquitoes is considered more likely.

When working in outdoor areas, it is important to direct the insecticide jet towards places that provide adult mosquitoes with cool, shady shelters (hedges, bushes, shrubs, garages, shaded areas, etc.).

On the other hand, it is not useful to treat the foliage of trees at heights above 3-4 metres. In fact, it is often windy, exposed to the sun, not very humid and therefore not conducive to the long stay of insects.

The distribution of insecticides is usually carried out by professional pest control companies using a knapsack sprayer or mounted on trucks and equipped with a motorized lance.

Contact between adult mosquito and insecticide may occur directly between the droplet and the insect in flight (felling effect) or, when the mosquito settles, by contact between the surface where the insecticide has deposited and the insect legs (residual effect).

A vector liquid (water) is used to disperse tiny droplets composed of water and formulated insecticide into the environment.

Adulticidal interventions carried out by means of atomiser can have a negative impact on the environment if not properly managed.

This equipment can in fact, if not properly set and handled, generate a drift of the product able to reach areas even very far from the treated area, going to eliminate non-target insects and creating discomfort to the population.

Precisely for this reason the sprayers should never be used in the presence of wind, even moderate.

It is also necessary to understand that all adulticidal insecticides are poorly selective and have effects also on useful insects.

It is for this reason that adulticide interventions should be carried out at certain times (e.g. late afternoon, dusk or early morning) when the presence and activity of mosquitoes is greater than that of other insects.

However, mistblowers and adulticide control in general are useful if they are part of an integrated control plan and become necessary if there are outbreaks of mosquito-borne diseases.

Post-professional mosquito pest control actions

After the intervention, if a liquid product with an adulticidal action is used, it is necessary to respect a return time that is provided by the operator of the disinfestation to the client according to the type of product used and which is generally at least 2 hours from the end of the product’s action time.

These operations are not necessary in the case of application of antilarvals.

The schedule of operations should be planned to cover the entire period of presence of the insects and should, if necessary, provide for the repetition of operations in the event of heavy rainfall.

The rains in fact take away the antilarval product present in stagnant water as well as residual insecticides present on green areas and sprayed surfaces.

The ineffectiveness of an intervention may depend on several factors that are linked to the operation of the technicians, the quality and correct concentration of the product used but also to the collaboration of the client and the environmental conditions.

An important action to be carried out during the months of presence of mosquitoes is to maintain and treat the vegetation with constancy in order to reduce the shelter and stationing points of these insects.

Remember to follow as scrupulously as possible the prevention advice that the pest control professionals offer the client and give the technicians the opportunity to scrupulously inspect the environments infested and to be treated.

The service protocols integrate preventive interventions, interventions to control larvae and breeding grounds, interventions to combat adult mosquitoes.

Getting rid of mosquitoes becomes possible and is risk-free.

The only treatment on adult mosquitoes (adulticide), in addition to being the one most often required and widespread, is also cheaper and the reason is that it is implemented with less time and resources on the part of the company, but almost always has a minimal effect and very limited in time.

Given that the final cost of a mosquito pest control depends on the various environmental factors that we have seen as well as the size of the area to be treated, on average a single intervention has a starting cost of 110.00 euros, for example for a garden up to 50 square meters.

Considering that a single intervention has a limited action in time, professional companies usually propose cycles of 6-8 interventions per season, with a cost of around 660.00 euros to go up.
