Dog flea - 

  • 1 - 4mm long with brownish-black colouring
  • can jump up to six inches
  • move from host to host and can infest lawns


Black House spider - 

  • webs can be found in the corner of window frames, logs and rock walls
  • bites are rare as the spider is timid but symptoms of nausea, vomiting or sweating should be checked by a doctor

Silverfish are small insects that are wingless and have a silvery, light grey/blue colouring.  They are typically around 13 - 25mm in length.  Being nocturnal and having the ability to move very quickly makes them extremely difficult to spot.

They are attracted to cool, damp places and will eat almost anything including books, wallpaper, photos, carpet and clothing.  Silverfish can live for a year or more without eating and usually lay around 100 eggs in their lifetime.

Silverfish are a household pest due to the destruction they cause to property.  They can also contaminate food but fortunately do not transmit disease.

If you find any evidence of silverfish activity, call Core Pest Management to have your property treated.

Daddy Longlegs - 

  • has extremely long legs in proportion to body length
  • feeds on small insects and other spiders
  • builds its web in homes and garden sheds
  • its bite is not capable of piercing a human's skin

Paper wasp - 

  • form small colonies and make paper nests under tree branches

           and eaves.

  • nest are shaped live inverted cones made of hexagonal cells
  • they can deliver a painful sting but are normally only aggressive

           when their nest is threatened


Wasps only sting when they feel threatened.

Once a wasp has stung you, they release an alarm pheromone which alerts other wasps to attack in order to protect their nest.  

Not only is the sting from a wasp extremely painful, it can be life-threatening to small children, pets and people who suffer from anaphylaxis.

The University of Melbourne has recently found that bees and wasps have killed the same number of people as snakes over the past thirteen years.

Please call Core Pest Management should you have any further questions or need your property treated.

Fleas are a type of wingless parasite that feeds off the blood of animals such as cats and dogs and humans.  They range from 2 to 8mm in length and are brown in colour.  Their head is disproportionately small and they have six legs, the hind legs being very large which enables them to jump long distances.  Their body is covered in microscopic hair that compresses when they move through animal fur.

The most common fleas you are likely to encounter are cat and dog fleas.  They rely on a blood meal from a host to survive.  Most fleas are introduced to the home by the family pet.  Unfortunately, flea eggs are not attached to the host but rather eggs will hatch on the ground, in places such as carpet, rugs, upholstery or even cracks in the floor.

A sign that your pet and home are infected by fleas is seeing your cat or dog continually grooming itself and scratching.  Adult fleas are easier to locate as they can be quite visible within your pet's coat.  Flea eggs and larvae are not so easy to locate.  They are usually found in out-of-the-way places such as under furniture, in your pet's bedding, carpets and floor cracks.

Fleas can cause considerable discomfort to family pets and humans.  A flea bite can be intensely itchy and sometimes painful.  Secondary infections caused by scratching are quite common.

A qualified Core Pest Management technician can determine the type, source and extent of the infestation, then use registered insecticides to control the problem.

Ants are very social insects that live in colonies.  An ant colony consists of a queen, workers and soldiers and the colony is active all year.

Ants are important predators in their natural environment and contribute to the recycling of nutrients in soil.  However, ants can be a real problem in domestic and industrial situations.

Many species of ants protect their colony by biting or stinging intruders and their sting can be extremely painful.

Certain species of ants will infest decaying timber in retaining walls, fences and building.  Other will nest in wall cavities, ceiling spaces and behind skirting boards.  Internal nests can be difficult to eradicate and can often be identified by small piles of gritty material near doors, window frames and skirting boards.

If you find any evidence of ant nests or have ants invading areas in your homes, call Core Pest Management to have your property treated.

Spiders are arachnids, not insects so have eight legs and fangs that inject venom.

Most spiders make silk which they use to create spider webs to capture prey.  Abandoned spider webs are called cobwebs.

Spiders can be found all over the world in nearly every type of habitat.  Queensland is home to some of the most deadly spiders in Australia so regular spraying for spiders is recommended.  While most spiders are harmless to humans, some species can bite and inject venom that can make someone very ill and be potentially life threatening to young children and the elderly.

Rats are larger in body size than a mouse and have a characteristically long tail.  Controlling the population of rats is very important as they are known to transmit dozens of diseases.

Once a rat has gained access to your business or home, they not only spread disease but they can contaminate food and cause considerable damage such as damage home's insulation, chew through floor joists and walls, chew on electrical cables.  Rats can even undermine landscaping around the home through their burrowing activity. 

If you find evidence of rats in your home, contact Core Pest Management immediately.

Funnel ants mostly live underground and make their presence known to homeowners by the funnels they leave on the lawn in the shape of volcanos.

The funnel ant builds nest cavities underground and deposits the unwanted soil in the shape of funnels on top of the homeowner's lawn.

They generally prefer sandy soils and tend to avoid broad leaf grasses.

If not treated, the funnel ants spread across the entire lawn.  Not only is this unsightly but the funnels can damage lawnmower blades.  The uneven lawn surface caused by the funnel ant can also be a risk hazard to homeowners and landlords.

Please call Core Pest Management should you have any further questions or need your property treated.

Mosquitoes are small, midge-like flies with 6 delicate legs and two wings covered in scales.  The females use their tube shaped mouthpart to pierce the skin of its host to consume their blood and on average have a life span of 2 - 3 weeks.

All mosquitoes must have water to complete their life cycle.  Mosquitoes breed in stagnant water.  This can be water in ponds, car tyres, plants, buckets, birdbaths, gutters or anywhere water is laying.

Mosquitoes are initially attracted by the carbon dioxide that we breathe out but as they get closer, they react to the chemical smells produced by bacteria and sweat on our skin.  Mosquitoes are not only a nuisance leaving an itchy, red welt where they have pierced and drawn blood from the skin but they are carriers of some of the most deadly illnesses.

Some of the diseases transmitted by mosquitoes in Australia include Dengue fever, Murray Valley encephalitis, Ross River virus, Barmah Forest virus disease and Zika.  These diseases can be life threatening so the control of mosquitoes must be made a priority for all homeowners and landlords.

Please contact Core Pest Management to assist in the control of these deadly diseases by taking the necessary steps to rid your property of the potentially dangerous insects.

Bed bugs are usually 4-6mm in length and oval in shape.  They are a dark, reddish brown colour.

They are a small parasitic insect that fed on human blood by piercing the skin but do not live or burrow into human skin.

They are extremely mobile but tend to stay close to their food source.  They can survive long periods without a blood meal.

Bed bugs are not a serious health threat as there is no evidence to indicate that they carry infectious disease but they are a nuisance pest.

They have flattened bodies so can stay well hidden in narrow cracks such as mattress crevices, on bed frames, picture frames and even behind wall paper, skirting boards and carpet edges.

Signs that indicate that you may have bed bugs include: live bed bugs on your mattress, dark spots on the mattress or sheeting, bite marks on your skin, usually in a distinctive line. These bites can be painful and some people can react to the saliva the bed bugs inject while feeding.  There are even a few individuals that can develop anaphylactic reactions to bed bug bites.  This type of reaction can be life threatening. 

If you think you have a bed bug infestation, contact Core Pest Management immediately as a delay in proper treatment of bed bugs may cause the infestation to spread which will then be more difficult to control.


Midges are an insect that is found practically everywhere around the world with the exception of extremely cold or extremely hot land areas.  They are around the size of a pin head.

Midges are well known for the severe reaction some people have to their bites.

It is only the female midge that bites.  She uses the blood she obtains as a protein source to develop her eggs.

Overcast conditions with minimal air movement and high humidity are perfect conditions for midges.  They tend to breed around the perimeter of water bodies.

They tend to bite around dusk to dawn but may continue to bit through the night.  On an overcast day, they can also bite throughout the day.

Midges aren't known to transmit any human diseases in Australia however, bites can often cause an allergic reaction that can be quite painful and irritating.  Some bites may blister and weep persistently for days or weeks.

The severity of the reaction will vary from person to person and some people can be desensitised over time. Others may experience a severe reaction where the bite mark will appear red and swollen, sometimes measuring several centimetres in diameter. 

Please call Core Pest Management should you have a midge problem at your property.
