Occasional pests In Dhaka City

Occasional pests are considered all those that appear at any time in the structures (homes, companies, industry, etc …). These are classified in three ways

• Occasional invaders: they appear at any stage of their life cycle.
• Pests attracted to light: these are attracted by the light, to the interior.
• Diverse plagues: they are those that complete their life cycle within the limits of the building.
• structures or alter the common development of activities.

Eight Types of occasional pest name in Dhaka

Spiders 

The main feature is its 8 legs which differentiate them from insects, have simple metamorphosis and have no wings or antennae. There are about 42,000 species and all produce silk (cobweb).

They receive the denomination of plagues when they enter the houses and other buildings. In the industry, in particular, its cobwebs that its food source provides are not well regarded by hygiene, aesthetic and safety factors in the food sector. In homes and in a small proportion they can bite residents (according to their species).
From another perspective, spiders are the largest natural insect controller, for this reason in some areas they are beneficial.
Control the best control for spiders is the elimination of cobwebs; This significantly reduces their presence since that is where they find their food.

Crickets

House crickets and field crickets usually invade houses. They are casual pests indoors especially in basements, dark and damp places that have dirty floors.
Crickets in considerable quantities can cause damage to certain fabrics such as linens, cotton, and others. Although they affect carpets, skins and even paper but only this is notorious in large quantities, in general, they feed on anything. Another annoying factor is the noise that is produced which is a call from the males to the females and is generated by rubbing their front wings together.
Control being closely related to cockroaches its way of control is very similar to the latter.

Centipede (Chilopoda)

There are two centipede and centipede classes of houses, the difference is in the size of the latter. Its habitat is usually humid areas under stones, trees, etc. And indoors bathrooms, basements and attics. Although its “bite” is dangerous to us, although it is not with its mouth part, but with its modified front legs (maxillipeds) that function as jaws and contain poisonous glands (cause some pain and inflammation) small species do not penetrate the skin; it is recommended in case of pickets to use antiseptic.
Application control of insecticide (residual) products and most importantly review and treat the places where they settle.

Millipede (Diplopoda)

Although they are similar to centipedes, they differ in their 2 pairs of legs in each segment of their trunk, while the centipede has only one pair per segment. These do not sting but release a very small amount of cyanide enough to irritate the skin; millipedes are also in humid spaces where there is decomposing material, they can invade homes if there are suitable conditions. Control is very similar to that of one hundred feet, but a more exhaustive control is recommended around the site to be treated, removing decomposing material and so on.

Scorpion (scorpions)

Scorpions become a pest due to medical involvement due to their bites, these can be similar to the average wasp-like sting, which can be complicated by an allergic reaction and is only fatal in some cases. They measure about 2 to 10 cm and their main feature is their stinger.

Control is a 5-step process, which includes identification, removal of shelters, food/dam reduction, exclusion and yes, pesticide application is required. The elimination of shelters consists of eliminating piles of wood, garbage, waste, wood, firewood and logs in gardens, this as a first step and one of the most important ones, together with the exclusion that would prevent their entry.

Little silverfish (Lepisma saccharina)

It is an insect without wings that are found throughout the world. Its name is received because its body is covered by silver scales and its shape of fish/carrot/tear. It has gradual metamorphosis and the scales appear on the third instar.

You can sit anywhere while you find the right conditions, your actions are at night and they feed on almost everything, contaminate the food of humans and can deteriorate books and others through their excrement.
Control the control of the silverfish is based on the identification of the areas preferred by these: Sites with low light, with some humidity, books and other places where they can find their food, are the places where the inspection is carried out; based on this, the conditions for their normal stay are reduced, then pesticides are applied according to the considerations of the pest control professional. It should be noted that in places where the infestation is in books the application should never be over these, otherwise the control must be strategic (cracks and bookcase cracks) without impregnating the books.

Slug

His name receives him to his very slow movement and/or his appearance. Inside, slugs are annoying but outside they cause severe damage to flowers, vegetable plants, and fruit trees. They can be found in different sizes, they have a pair of inconspicuous upper tentacles that usually contain their eyes. Their displacements are made by sliding on the mucous film. The slugs are nocturnal, in the day they hide in protected and humid places (below: logs, rotting boards, stones, wooden paths, among other places with moderate humidity levels). Slugs can feed on the surface to the underground part of the plants they wish to attack; In high proportions, they can generate multiple losses.

Control This is a 4-step control that includes identification, hygiene, physical removal and application of control materials.

Snakes

Most of the snakes that we can find near humans are harmless, as many people have a significant fear of all snakes and do not tolerate them around their structures. Because some venomous snakes occasionally visit houses or structures located near places infested by snakes. It is important to know the difference between venomous and non-venomous snakes.

Poisonous snakes: prominent triangular head and relief hole between the eye and the nostril. As well as elliptical pupils.

Non-poisonous snakes: these have narrow heads, lack a relief hole, between the eye and the nostril, have rounded pupils.
Snakes are predators and feed on a variety of live animals frogs, toads, rodents and birds among others.
Control due to its variety of habitats is very complicated to eliminate a population of snakes.

Therefore one of the best ways to control them is to remove as many shelters as possible, sites such as mounds with stones, piles of wood, tall grass and other vegetation in the surroundings should receive corrective actions. Exclusion barriers play an important role in preventing their entry.
In addition, good rodent control reduces the presence of snakes because these are part of their diet, finally, for the rest of cases you can use traps for strategically located rodents (cages, sticky traps, among others) and in capture situations specific and safety procedures must be followed for handling.

Bats  (considered a vertebrate pest)

Bats are nocturnal flying mammals that inhabit dark and hidden sites, traditionally have been associated with witchcraft and other myths. Many of these myths cause unfounded fear in people. They are of medical importance because a small percentage of them are infected with rabies and their wastes support the fungal organism that causes histoplasmosis lung disease. There are about 980 species of bats in the world.

Biology bats are biologically useful animals because they feed on insects, some help pollinate and bats rarely attackman, the problem begins when the “guano” their excrement begins to attract a variety of insects, stain the walls and cause respiratory diseases. When they enter the structures they do it in hot seasons and when they are about to procreate this they do it to have nurseries or maternity colonies.
The gestation period is 50 to 80 days the young are born naked and open their eyes in 2 or 3 days, usually the young are left hanging on the perches of the nest. The average life of the bat is 4 to 10 years; Its survival is influenced by its sense of echo radar location.

Control the first considerations in a control for bats are the legal factor since they may be subject to protection by government entities, the other factor to consider is the location of the point to be treated as bats select structures that are close to the water and food where adequate numbers are found another consideration would be the structures that presented former colonies.
For an effective bat control after taking into account the above considerations, an inspection and assessment process is carried out analyzing the following factors:
• All bat entry and exit points.
• Structural deficiencies of the building that contribute to the infestation.
• The perching site of the bats within the structure.
• Colony size infested and
• The plague bat species.
To carry out this work, at least two inspections are required: one inspection at dusk when the bats emerge from the structure and the second during the day, to determine the interior perching sites and other considerations to determine the action plan. It should be remembered that bats always emerge every sunset, unless it is raining or it is too cold, for inspections in the sunset it is important to have two or more people to check in the opposite corners of the structure.
Each action plan to control bats can be different according to the different variables, but the main premise for the treatment of these is exclusion.
