Mosquitoes are small flying insects that belong to the Culicidae family. There are more than 3,500 mosquito species worldwide, with around 300 species found in Australia. Many mosquito species are known for their biting behaviour, which can cause irritation and discomfort.
Female mosquitoes feed on blood because it provides the protein needed to develop their eggs. Some species are also associated with diseases such as Dengue Fever, Ross River virus, Barmah Forest virus, and Encephalitis, making mosquito control important in areas where mosquito populations are high.
Aside from potential health concerns, mosquito bites can also cause itching, redness, and swelling, which can make outdoor activities unpleasant. In areas where mosquitoes are active, their constant buzzing and biting can disrupt recreational, social, and work activities.
Understanding the mosquito life cycle helps explain how quickly mosquito populations can grow.
A female mosquito typically lives two to three weeks, while males usually have a shorter lifespan. Both male and female mosquitoes feed on plant nectar and fluids, but only females require blood meals to produce eggs.
Mosquitoes are attracted to humans by several factors, including:
Body odours
Carbon dioxide from breathing
Body heat
Air movement
Female mosquitoes lay their eggs in stagnant water. Once the eggs hatch, mosquito larvae develop through four larval stages (instars) before becoming pupae. After approximately two weeks, the pupa transforms into an adult mosquito.
Within just a few days, the new adult mosquito is ready to feed, mate, and begin another breeding cycle, allowing mosquito populations to grow quickly when conditions are favourable.
Reducing mosquito exposure often involves managing mosquito activity both indoors and outdoors.
Occasional mosquitoes entering the home can be managed using aerosol insect sprays designed for flying insects. Spraying directly toward the mosquito or lightly into the air can create a fine mist that helps control flying insects.
If multiple mosquitoes are present indoors, it may help to treat areas where mosquitoes commonly rest during the day. These areas often include:
Behind cupboards and furniture
Inside wardrobes or drawers
Behind picture frames
Dark corners and sheltered indoor spaces
Installing insect screens on windows and doors can also help reduce mosquito entry.
Outdoor mosquito activity can often be reduced by targeting areas where mosquitoes rest during the day. Mosquitoes prefer cool, shaded, and sheltered locations.
Common outdoor resting areas include:
Under eaves and patios
Beneath decking structures
Under plant leaves and dense vegetation
Along exterior walls near outdoor living areas
Treating these areas around the property can help create a protective zone that reduces mosquito activity around outdoor spaces.
Mosquito activity around a property can increase quickly if breeding areas are nearby.
Common signs of mosquito problems include:
Frequent mosquito bites while outdoors
Mosquitoes gathering around lights in the evening
Buzzing sounds around outdoor areas
Mosquito larvae visible in standing water
Increased mosquito activity after rainfall
If mosquito activity becomes persistent, professional mosquito treatments may help reduce mosquito populations around the property.
Mosquitoes lay their eggs in stagnant water, which means even small water sources can become breeding sites.
Common mosquito breeding areas include:
Blocked gutters and drainage areas
Bird baths and decorative water features
Plant pots or trays that collect water
Buckets, containers, or outdoor equipment
Garden ponds and water storage containers
Areas where rainwater accumulates in the yard
Regularly checking and removing standing water can help reduce mosquito breeding opportunities.
Large mosquito populations often develop where standing water is present nearby, allowing mosquitoes to breed quickly.
Mosquito infestations may become noticeable when outdoor areas become uncomfortable due to frequent mosquito bites. In some cases, mosquito activity may increase during warmer months or after periods of rainfall.
Professional mosquito control services can help identify breeding sites and apply treatments designed to reduce mosquito activity around the property.
Mosquito control typically begins with a detailed inspection to assess the level of mosquito activity and locate potential breeding areas.
Based on the findings, a treatment plan may include:
Targeted insecticide applications
Larvicide treatments for water sources
Recommendations to reduce mosquito breeding areas
The cost of mosquito control services can vary depending on several factors, including:
The size of the property or outdoor area
The severity of the mosquito problem
The number of treatments required
The treatment methods used
After inspection, technicians can recommend the most appropriate mosquito control solution based on the specific conditions of the property.
If mosquito activity around your property is becoming difficult to manage, professional mosquito control services can help reduce mosquito populations and improve outdoor comfort.

Adult female mosquitoes usually live for 3–4 weeks, while males only survive for around a week. The full life cycle from egg to adult can be completed in as little as 5 days in warmer climates, but more commonly takes about 2 weeks. In cooler conditions, it can take longer.
Mosquitoes detect carbon dioxide released when animals and humans breathe, allowing them to locate a host from a distance. As they get closer, they use body heat and chemicals released from the skin to find their blood meal.
In general, mosquitoes are not strongly attracted to UV light, which is why bug zappers are ineffective against them. Whether mosquitoes are drawn to or repelled by light depends on the species and the time of day. For example, night-biting mosquitoes avoid light during the day. Because of this, light traps are not considered an effective mosquito control method.
In most regions of Australia, mosquitoes are most common between November and April. In tropical northern areas, they can be active all year round.
Biting behaviour varies by species, but most mosquitoes in Australia are active at dawn and dusk (twilight), following their natural body clock.
Mosquitoes are weak fliers and usually remain close to their breeding sites. After feeding on blood, they rest to digest the meal and develop eggs, which are then laid in nearby aquatic environments. Eggs can remain dormant until warmer weather triggers hatching.
To reduce mosquitoes around your home, remove standing water where they breed, such as in bird baths, gutters, or plant saucers. Use repellents, citronella candles, or install outdoor screens to help keep them away. Mosquito traps or professional treatments from Pest-Ex can provide long-term protection. Planting mosquito-repellent plants like lavender or citronella grass can also help minimise their numbers.
