Weeds Control

Answer the following question: only farmers need weeds control?

If your answer is YES, then you are WRONG; but if your answer is NO, then you are CORRECT. Amenity areas such as parks, aquatic areas like ponds and pools, hard surfaces like footpaths and pavements, and car parks also need weeds control.

Weeds in grass, growing unevenly in amenity areas create an untidy appearance that increases cost for groundsman to carry grass cutting to maintain. Uncontrolled weeds growing on footpaths and pavements, lead to surfaces breaking up, not only does this create a potential danger to pedestrians, but it is also unsightly. Besides, it is always the breeding ground for various kinds of pests, particularly mosquitoes with capabilities in transmitting disease such as Malaria, Dengue Fever and Encephalitis to humans and animals.

We employ wide range of accurate weeds control products, from herbicides to grass cutting machine, ensuring that a cost-effective solution is achieved, whilst ensuring that the environment is protected.

Herbicides (chemical weeds killers) may be used under certain conditions to control some weeds but there is no herbicide that can be used on all vegetable crops that will control all weeds. The use of herbicides in a home garden requires special planning and careful application.

Most annual weeds can be controlled by cultivation! Annual broadleaf weeds are easily removed while they are in the seedling stage. Cultivations should be made to control each flush of weeds that emerges, usually within a few days after a rain. At this time weeds seedlings are easily uprooted.

Birds control

Droppings are unsightly, unappealing, and render walking surfaces underfoot slippery and dangerous. Birds and their droppings create unsanitary conditions and can cause transmissible diseases. Droppings cost money. Cleaning crews, related equipment, and time spent can generate large financial outlays unrecoverable by revenues. Birds are destructive to public and private facilities, any of which can lead to large financial losses. They halt operations and make repairs necessary by entangling themselves in machinery or downing power lines. They even nibble at, or even tear out insulation.

That is why effective birds control is very important. Products for birds control can be categorised into 4 kinds:

Physical barriers (needle strips, sticky gels, netting)
Sound repellers
Taste aversions
Visual deterrents

With our professional advice and effective products for birds control, those negative effects brought by birds can be limited. The products we provide are as follows:

BirdShield™ Bird Repellent

Silent, Invisible, Harmless, No Electricity

ˇ@

Food-grade, biodegradable bird repellent repels birds from nesting, loafing and roosting in and upon structures, roofs, interior or exterior walls, siding, statues, bridges and other sites ˇV even nests. Also deters water birds from boat docks and marina areas.

Birds' trigeminal system, similar to our sense of smell, is irritated by BirdShield's smell.

It's environmentally friendly and harmless to birds.

Developed with assistance from a major university, BirdShield's active ingredient is Methyl Anthranilate (MA), a constituent of Concord grapes. MA has been used by the food and drug industry for over 40 years to flavor candy, sodas, gums, and drugs; it is listed by the US FDA as "Generally Recognized As Safe" (GRAS) and is classified by the US EPA as "reduced risk".

Able to repel...    "Sparrows Starlings Barn Swallows Pigeons Gulls Water Birds Woodpeckers Predators Etc."

Life of Applied Product Porosity and sunlight determine BirdShield's life. Up to 3-4 weeks on a porous surface; slightly less on a non-porous or sealed surface. Often, a single application brings permanent success. Reapplication may sometimes be necessary for long-term deterrence in entrenched situations. After 2-3 applications, even stubborn birds learn not to return.

Invisible Solution can't be seen or heard by neighbors, customers or employees.

Usage and Coverage Paint (full-strength) or spray (1:1 dilution with water). On a porous surface, you'll get less coverage but it will last much longer - apply liberally as product will be absorbed. For example, a gallon may cover a medium-sized rooftop. On a non-porous or sealed surface you'll get maximum coverage but must apply more often - apply lightly as excess will run. BirdShield is effective on all surfaces but as it may stain or damage certain materials (waxes, plastics, foams, insulations and glues) or finishes, we suggest testing and/or sealing.

Original tests were done in five commercial buildings in Lewiston, Idaho. All of the structures had been built between 1880 and 1920, and pigeons had been roosting in them as long as anyone could remember. Prior attempts had been made to remove the pigeons by various means, including trapping and scaring with noise, balloons, and plastic owls. None of these attempts were successful for any reasonable period of time. During these tests, three buildings were treated with a 1:1 solution applied to roosting areas with a hand pump sprayer. On the other two buildings, a similar treatment was made with water only, for comparison. Immediately before the tests, one day, three days, and thirty days after, objective tests of the bird use were made. The number of birds that perched in an area for more than 30 seconds was counted for each building. In the buildings treated with water only, this number did not change significantly over the life of the study. In stark contrast, there was no reportable bird activity observed at the treated buildings. Similar results have been observed for starlings, sparrows, and woodpeckers in other test environments, however it was sometimes necessary to re-treat two or three times in order to obtain complete control.

Feral Pigeon Columba Livia


Repel pigeons with a vinyl inflatable predator by using helium frightens birds pests away! Huge 2-foot hanging ball has menacing, moving eyes on front and back that strike fear in birds!

The feral pigeon is the number one urban pest bird. Large numbers exist in every city across the country. Not a native bird, feral pigeons are descendants of domestic homing pigeons brought over from Europe and released here in the 1600s. They were domesticated from the wild rock doves from the sea cliffs of Europe by the Romans over two thousand years ago. Several traits have allowed them to dominate the urban landscape. Because of their history, pigeons are not afraid of people; they roost and nest readily in man made structures and they have a diverse diet. The standard pigeon has a short neck with a small head. Their short legs with the level front and hind toes allow them to perch on branches as well as walk on flat surfaces.

Damage
Feral pigeons are responsible for untold millions of dollars of damage each year in urban areas. The uric acid in their feces is highly corrosive. Also, debris from roosting flocks can build up, backing up gutters and drains thus causing damage to roofs and other structures. Extensive damage to air conditioning units and other roof top machinery is commonplace. There are also other economic costs that can be associated from pigeon's taking up residence such as slip and fall liability and projection of an unclean, dirty company image. Besides physical damage, the bacteria, fungal agents and ectoparasites found in pigeon droppings sometimes represent a health risk .

Control
There are a wide variety of solutions available for handling a pigeon infestation. The best solution for pigeon problems, is complete exclusion with a 2" mesh StealthNet . Many ledge problems can be solved by using products such as BirdCoil , Birdwire , Bird-Flite spikes, as well as Bird-Shock electrical track. When bird pressure is heavy in an area, exclusion work must be accompanied by flock dispersal methods like trapping or use of moving predator effigies like the Rotating Screech Owl . Flock dispersal alone is not a long term solution especially in medium-heavy pressure situations like when there are food/water/shelter sources at the site.

Nesting
Nest building is very simple and often consists of a few stiff twigs. The male will pick the site. They prefer small flat areas away from the ground. Look for nests along building ledges, bridge supports, air conditioning units, window sills and the like. In crowded flocks, pigeons will even forgo nest building and lay eggs directly on a protected ledge.

Breeding
Pigeons are monogamous and a mating pair will typically have three or four broods a year. The female will usually lay two or sometimes three eggs at a time. The eggs are a solid bright white color. The eggs take roughly 18 days to hatch and 35 more days before the fledglings leave the nest.

Cycles

Pigeons are not migratory. Their natural instinct is to stay near their birth site. This trait gives the pigeon a very determined personality when it comes to roosting at a particular site, much to the dismay of the inexperienced pest control technician.

The daily cycle of a pigeon is :

to roost at night

feed in the morning
loaf in the afternoon

The seasonal cycle is as follows:

courtship in the early winter

nest building in late winter
breeding in the spring

* However, in warm climates, breeding will occur year round. Pigeons molt once a year in late summer.


The feral pigeon is generally blue-gray with a white rump; has iridescent feathers on head and neck; two broad black bars across each wing and a broad dark band across the end of the tail. They also can display white, brown or gray plumage.

House Sparrow (Passer Domesticus)

The House sparrow is the number two urban pest bird. Introduced as a species to North America , the house sparrow quickly spread across the country due to its lack of natural enemies and its adaptive traits. Its ability to nest in urban structures, eat urban scraps and a large breeding capacity are some of these adaptive traits. The House Sparrow is actually a member of the weaverbird family and not a true Sparrow. Weaverbirds create intricate nests and relative to their size, the largest nests in the bird world. Their legs and toes are favored for branch perching and their short conical bills are ideal for seed cracking. Their diet consists of seeds and grain, as well as fruits, vegetables, human table scraps and insects. They are boisterous, intelligent birds who roost in noisy flocks on branches of city trees, ivy covered walls and under eaves of houses.

Damage
House Sparrows are often a nuisance in urban areas like manufacturing and food processing plants. Gutters and drainage pipes clogged with sparrow nests can backup and cause extensive water damage and fires have been attributed to electrical shorts casued by machinery housing sparrow nests. Lastly, feces buildup can lead to structural damage from the uric acid in droppings, plus the bacteria, fungal agents and parasites in the feces also pose a health risk .

Control
The most effective method of control is to exclude sparrows from the area with 3/4" StealthNet , making sure there are no gaps or crevices for the birds to pass through. The only ledge deterrent systems that are truly effective against sparrows are electrified ledge systems that use an intermittent pulse like Bird-Shock . New 2-chambered Sparrow Traps are quite effective at trapping small quantities of sparrows. The best trap has an elevated second chamber that keeps the birds happy and so content that they actually sing, attracting others to the trap. When practical, the trapping program should be combined with a nest removal program that will greatly reduce the population over time. Along with trapping, mist nets can be installed in the flight paths by certified personnel to capture these birds in enclosed areas. A new technique that has found some success for moving populations is to fog problem areas with ReJeX-iT . This method is most commonly applied when sparrows gather in flocks. Sparrows generally do not react to audio and visual products except occasionally in areas to which they are not very committed (new to area).

Nesting
They build large nests relative to size which function as the center of all activity. They prefer small enclosed places such as house shutters, drainage piping, building rafters and corrugated metal siding. They will build a spherical nest in a tree or another exposed place if they have no other option. The building material will be sticks, with an inside lining of grass, string, fabrics or straw. The nest will often hold several families.

Breeding
House sparrows only mate for a season. They average three broods per mating season with each brood containing four to seven eggs with 20 offspring a year average. Egg coloration will be white, pale blue or pale green with a few gray or brown dots. If unchecked, a breeding pair can grow to over 2,000 birds in two to three years.

Cycles
House Sparrows are not migratory, but in cold climates can show movement between rural/suburban breeding sites and warmer winter roosting sites in the city. House Sparrows are aggressive birds and will often force out other birds from their territories. They are flocking birds and will gather in the thousands to take over feeding and roosting areas.

Male House Sparrow have black throats and chest patches, light cheeks and brown nape. The female has a plain brownish chest and dull eye-stripe.
