Pest Descriptions

Gisborne Cockroaches
20-45 mm long. Usually dark brown with creamy colored fringes. Can also be seen in lighter colours depending on how long ago they shed there skin, immediately after they have shed there skin they will appear to be nearly white but this colour will darken as their exoskeleton hardens. They exist on a diet of decomposing vegetation, can often be found in woodsheds and in and around plants that have a deep cover on decomposing leaves. They can be a problem in and around homes. Being nocturnal they will hide in dark places during the day. Want to know more ? http://en.wikipedia.org/wiki/Drymaplaneta_semivitta

German Cockroaches
1.1-1.6 cm long. Colors range from brown to nearly black with lighter steaks along the sides. They have an obvious set of wings but are not known to fly. Will shed there skin at regular intervals to enable growing. They will seek cover in dark places cracks and crevices. They can cause serious health issues and they are known to carry harmful bacteria that they spread over food, preparation surfaces and utensils.

Spiders
We have many species of spiders some may have toxic bites. Most spiders are not dangerous to humans but a few like the Australian White Tail spider can give a nasty bite that may become infected. White Tail spiders are ground dwelling spiders usually predate other spiders so reducing the amount of spiders will reduce the chances of encountering this spider.

Flies
We have a number of species of flies most are more prominent during the warmer months , they can be unhygienic as they walk over food and food preparation surfaces as they have a simple digestive system they regurgitate the stomach juices onto the food to aid in digestion.

Fleas
They can give a bite that will become itchy and later may become infected from scratching. Fleas have a 4 stage life cycle egg, larva, pupa, and adult. The times allowed for these stages will often be dictated by the temperature the hotter the temperature the faster development will occur. Fleas will often lay dormant in a house that is empty and become active when vibrations signal that there are living creatures
moving that indicates that there is a meal to be had. Usually associated with cats and dogs but also can be transported to a home where
there are no pets by visiting a property where there are fleas active they may hitch a ride home with you and a single female could start a new infestation. Want to know more ? http://en.wikipedia.org/wiki/Flea

Mice
Adult 7.5 -10 cm. Tail 5-10 cm. Feral mice colors range from light brown to dark grey House mice thrive under a variety of conditions: they are found in and around homes and commercial structures, as well as in open fields and agricultural lands. They are usually a problem in the cooler months when they will invade a house searching for food and warm and dry nesting sites. Left uncontrolled can breed prolifically, a single female could have between 5 – 10 litters in a single year, populations can increase dramatically over a relatively short period.
Life expectancy in the wild is mostly less than a year, in a protected environment a mouse can live up to 3 years. Mice can cause health issues as they can carry harmful bacteria, fleas and mites. They also will defecate and urinate on food preparation surfaces and utensils.

Rats

Norway Rat
Adult up to 25 cm. Tail 10-15 cm. Commonly called the water rat, usually nests in lower areas as they are poor at climbing but burrow very well, will often live in a colony. When food is in short supply the lesser members of the colony will die off first, will often breed in relation
to the quality and quantity of there food supply. Want to know more ? http://en.wikipedia.org/wiki/Brown_rat

Black Rat
Adult 15 – 22,5 cm Tail 17-25 cm. They are commonly called the roof rat. Climbs very well and will often nest in roofs and higher places. Can also adapt to nesting in lower areas. Will often have a limited home range in which they will forage for food. They can carry a number of bacteria also fleas and some mites. Rats can cause damage to buildings and electrical wiring as they have the habit of gnawing. They are mostly a problem for homes in cooler months when they will search for food and warm sites to nest.

Ants
We currently have 40 spices of ants confirmed in new Zealand some are native some are introduced species, some are classed as invasive species.

Argentine Ant
They are commonly found when pulling back the grass at the edge of a footpath. Foragers collect honeydew from scale on citrus trees and aphids. They will also collect nectar from flowers. Trails can often be found on flowering trees and shrubs. Nests can be found under wood, stones, piles of leaves in potted plants, compost bins and piles. This species of ant can be invasive living in colonies with multiple queens
and segmented nests. Want to know more ? http://en.wikipedia.org/wiki/Argentine_ant

White Footed House Ant
Species are general scavengers, form long foraging trails and often enter houses in search of food and water. Workers can be recognised by their habit of raising the abdomen while in motion.

Black House Ant
Is often found foraging in houses where they show a preference for fluids and sweets. Want to know more ?

Some species will prefer a diet of sweet foods and will often invade a home in search of these items. Other species will prefer a diet of mostly proteins this they will find in dead insects and plants. Want to know more ? http://en.wikipedia.org/wiki/Ant

Borer
There are a number species of borer that cause damage in new Zealand homes. But they all operate in a similar way. Adults lay eggs upon unpainted or unprotected wood there larvae hatch and burrow into the wood following the veins of the wood feeding on the cellulose in the wood they will exist in the wood for a number of years until they reach maturity when they will pupate into the adult beetle. Burrowing out of the wood will leave a flight hole which can very in size depending on the species when the life cycle will start over with adults laying the next generation of eggs. Over a number of years borer can do a large amount of damage to the wood. Where as the damage is not as substantial as would be caused by termites it is still serious and can effect the value of your home. Want to know more ? http://en.wikipedia.org/wiki/Woodboring_beetle

Bees
Bees are not commonly regarded as a pest but can cause problems when they swarm we will commonly refer requests to an apiarist so a swarm can be removed. Rarely as a pest controller do we have reason to take care of bees but in some situations it is necessary. Want to know more ? http://en.wikipedia.org/wiki/Swarming_%28honey_bee%29

Wasps
We have a number of species of wasps in New Zealand some native some are not. Wasps can be dangerous in a number of situations, they will defend there nest vigorously so approaching or disturbing a nest can result in being stung multiple times. At different times of the year they will seek out varied food sources when insects are plentiful they will predated other insects as the months cool they will seek out other sources of protein usually rotting or decomposing food or fruit.

Silver fish
Silver fish within a home can cause a lot of damage to a variety of items. Their diet is not solely confined to paper and books. Silver fish will consume and damage cotton glues carpets and various other items. While being nocturnal by nature will often be found in dark places like wardrobes, cupboards and even behind furniture. The damage cause can result in treasured items being damaged and destroyed. With the
removal from sale of some of the products commonly associated with treating of silverfish like mothballs and naphthalene flakes because of the clastogenic properties a pest controller should be consulted Want to know more ? http://en.wikipedia.org/wiki/Silverfish

Stored product pests
Stored product pest include weevils, Indian meal moth, and flour mites. To name a few, most of these pest infest and consume stored products. They live feed breed and defecate within stored products causing products to become no longer fit for human consumption, regular inspection of stored products will help identify these at the early stages of infestation. Once they become established you will need expert advice to remedy this problem, at the early stages of infestation disposing of infected product may solve this problem quickly, this problem is usually introduced by bringing infected products into your home, inspecting packaging of stored product when purchasing will help you avoid this problem , do not buy any stored product that has damaged or discolored packaging.
