6 to 7 mm
π¨ Covering & Coloration
House flies are usually gray with black stripes and reddish eyes.
Head
The head of a house fly is large, hemispherical, and features prominent compound eyes, short antennae, and specialized mouthparts adapted for sponging up liquids.
𦡠Appendages
House flies have six jointed legs, each attached to the thorax, which they use for walking, climbing, and tasting surfaces.
β Features
House flies have specialized mouthparts adapted for sponging up liquids, allowing them to feed on a wide variety of substances. They possess rapid reproductive cycles, with females capable of laying hundreds of eggs in their lifetime. House flies can detect food sources from considerable distances using their acute sense of smell. Their wings beat extremely fast, enabling agile flight and quick escape from threats. Additionally, house flies are known for their ability to walk on vertical surfaces and ceilings due to sticky pads on their feet. They also play a role in the transmission of various pathogens, making them significant from a public health perspective.
π Habitat
House flies are most commonly found in areas where humans live and food waste is present. Typical locations include kitchens, garbage bins, compost piles, animal shelters, food processing facilities, markets, and outdoor areas with decaying organic matter.

Key Characteristics of Cluster Fly in Derry Pest Control: Size, Habitat and Unique Features
π Overall Size & Shape
8β10 mm
π¨ Covering & Coloration
Cluster flies are dark gray with golden or yellowish short hairs.
Head
The head of a cluster fly is short and broad, with large reddish-brown compound eyes and short, feathery antennae.
𦡠Appendages
Cluster flies have six legs, like all insects, which are slender and adapted for walking and clinging to surfaces.
β Features
Cluster flies have a distinctive life cycle, as their larvae are internal parasites of earthworms. Unlike many other flies, they enter homes in large numbers to overwinter, often gathering in attics or wall voids. They are sluggish fliers and tend to cluster together when at rest. Cluster flies emit a characteristic, slightly sweet odor when disturbed. They do not breed indoors or feed on human food, which sets them apart from common houseflies.
π Habitat
Cluster flies are most commonly found in attics, wall voids, basements, and unused rooms of homes and buildings, especially during autumn and winter. Outdoors, they are often found in grassy areas, fields, and gardens where earthworms (their larval hosts) are present.

Key Characteristics of Blow Fly in Derry Pest Control: Size, Habitat and Unique Features
π Overall Size & Shape
6β14 mm
π¨ Covering & Coloration
Blow flies are metallic blue, green, or bronze in color.
Head
The head of a blow fly is large and rounded, featuring prominent compound eyes, short antennae, and specialized mouthparts adapted for sponging up liquids.
𦡠Appendages
Blow flies have six jointed legs attached to their thorax, each ending in claws and pads that help them walk on various surfaces.
β Features
Blow flies possess a remarkable ability to detect decaying organic matter from great distances due to their highly sensitive olfactory receptors. They are among the first insects to colonize decomposing remains, making them crucial in forensic entomology for estimating post-mortem intervals. Blow flies also exhibit rapid reproductive cycles, with eggs hatching into larvae within hours, and their larvae play a significant role in nutrient recycling by breaking down dead tissue. Some species are used in maggot therapy, where sterilized larvae help clean non-healing wounds by consuming dead tissue while sparing healthy cells.
π Habitat
Blow flies are most commonly found in areas with decaying organic matter, such as garbage dumps, compost piles, animal carcasses, and feces. They are also frequently seen around slaughterhouses, farms, and outdoor pet areas. Indoors, they may be found near trash bins, drains, or any location with rotting food or dead animals.
