The Bird Netting
The Bird Netting – There are so many varieties and styles of nets against pigeons, seagulls, and starlings, HORTOMALLAS® offers a different type according to the type of application.
There are many ways to deter birds from crops using bird netting, whether it’s for a balcony, roof, warehouse, or aquaculture farming pond with bird netting. However, neither ultrasonic devices, plastic predators, cannons, scarecrows (nor poisons) can effectively control this pest in the long term. If left uncontrolled, they can destroy entire crops in a matter of hours. Birds tend to nest in almost any location, which is why spikes are an ineffective method.
There are different types of nets and meshes used as passive protection against urban birds. The advantage of using a bird netting that passively prevents birds from passing through is that it physically denies them access without harming the animal. By preventing a bird from achieving its nesting or feeding goal, one can prevent the development of habits among colonies and flocks that would perpetuate in successive generations.
Obviously, the weight of the product affects its durability over the years and its exposure to sunlight.
This consideration must be taken into account when estimating the installation cost (including specialized labor, scaffolding rental in many cases, and cables). The larger the span to be covered, the more intermediate support cables will be needed. The netting itself may be able to withstand very long spans.
Bird nets can be classified into three main groups: Extruded nets, Knotless woven nets, and Knotted woven nets
Extruded: These nets are classified as extruded nets, such as CHICKENMALLA® with two mesh sizes of 16x19mm and 25x25mm (heavy-duty, 50 grams per m2) and GUACAMALLA with a mesh size of 20x20mm (lightweight, 10 grams per m2). The advantage of an extruded net is its durability compared to its woven counterparts, as it is made of a single “thread” and can withstand the sun for a longer time. In agriculture, the extruded net GUACAMALLA is widely used in temporary applications (seasonal crops) as it is easily recoverable and reusable for the following year.
Knotless woven: This lightweight type of net, GUACAMALLA-T, has a mesh size of 2x2cm and weighs 9 grams. It is very economical and comes in widths of 2, 4, and 5.2m. This allows for covering larger areas in less time.
Knotted woven: This type of net is produced by first creating a very resistant polyethylene cord and then weaving this cord by knotting it to create the mesh. These nets undergo a tensioning process inside a steam autoclave, which ensures the knot. HORTOMALLAS® offers BAXTOP® nets of various mesh sizes, with the most common being 5x5cm (8 filaments of 0.27mm, cord of 1mm) and 2x2cm (6 filaments of 0.27mm, cord of 1mm), with the smaller mesh size being heavier (68 grams) than the larger mesh size (30.88 grams).
Comparison of various Bird Netting:
Eliminating Pigeon Infestation with Nets and Meshes.
The most common problem in urban areas is the nesting of entire pigeon colonies, whether it be in houses, apartments, balconies, terraces, under roofs, or on building facades and cornices (where they often seek shelter from the elements). The problem of having pigeons too close to areas where we live is not only unsightly and unpleasant to see their droppings on railings, floors, and walls, but also the potential health risks posed by bacteria and viruses transmitted by these birds, as well as the possibility of them carrying parasites.
GUACAMALLAS® The Bird Netting
When it comes to permanently covering the entrance to pigeons on balconies, roofs, warehouses and industrial areas, it is best to use the GUACAMALLAS. If it is for the facades of historical buildings, the lighter and more invisible GUACAMALLA is recommended.
Protect Birds from Leach Ponds
There are European and US regulations that require companies to safeguard wildlife during industrial processes. Preventing migratory birds from entering leachate ponds in landfills or cyanide leaching ponds in mining is not only a legal requirement but also a matter of eco-ethics for the benefiting industries. These are extensive surfaces where a thick and wide mesh is placed on top of the cable network that will be installed over these ponds to make the installation more efficient. BAXTOP® is recommended, and in case of specific needs, we can produce the mesh according to the client’s specifications.
Bird Protection in Agriculture
In many articles, we have emphasized the importance of protecting open-field fruit crops by covering trees and shrubs with a mesh that can be recovered and stored each year. The most commonly used mesh models for this application are GUACAMALLAS® and GUACAMALLAS-T, thanks to their low cost and ease of installation and removal. The same mesh is also used to cover access to frugivorous birds in berry macro tunnels (blueberries, raspberries, strawberries, and blackberries).
With a properly installed GUACAMALLAS® bird netting in a macro tunnel, you can prevent these animals from consuming your crops
With GUACAMALLAS-T, entire orchards can be protected in a very cost-effective way.
To protect aquaculture ponds from pelicans, seagulls, and other seabirds, a similar concept and installation method can be used as with leachate ponds. However, the aquaculturist may choose to install a lighter mesh such as BAXTOP®, as many crops are temporary and do not require heavy-duty mesh. Lightweight meshes like the GUACAMALLAS® series (small mesh size) or HORTOMALLAS® (large mesh size that prevents the flight of larger birds) are commonly used.
Fish crops are easy prey for seabirds, but with proper bird control measures, significant losses can be prevented.
Here at HORTOMALLAS®, we do not produce or have any interest in being involved with nets for the capture of wild birds or bats.
We avoid commercializing this type of nets due to the unfortunate fact that they are often used to capture exotic.
