Identify the pest before it becomes a treatment problem.

The most common and troublesome cockroach species in Indian homes. Small (10-15mm), light brown with two dark parallel stripes behind the head. Prolific breeders — a single female and her offspring can produce 100,000+ descendants in a year. Thrives in warm, humid environments near food and water — typically kitchens and bathrooms.

The largest common cockroach species in India — 35-40mm long, reddish-brown with a pale yellow figure-8 pattern behind the head. Strong flyer (especially males). Prefers warm, damp, dark areas: drains, sewers, basements, manhole chambers. Often enters homes via plumbing stacks during heavy rain.

The most destructive termite species in India. Lives in underground colonies of 60,000 to 1 million members. Builds distinctive mud tubes to travel between nest and food source (your wooden structures). Can consume 15 grams of wood per day — a mature colony can structurally damage a home in 6 months.

The most common rat species in Indian urban homes. 16-22cm body plus 19-25cm tail, black or dark brown with lighter belly. Excellent climbers — typically nests in attics, false ceilings, and upper floors. Nocturnal and neophobic (suspicious of new objects), making trapping challenging without professional protocols.

The primary vector for dengue, chikungunya, zika, and yellow fever. Small (4-7mm), dark with distinctive white stripes on legs and a white lyre-shaped mark on the back. Day-biter, most active at dawn and dusk. Breeds in clean standing water — flower pots, cooler trays, discarded containers, tyre piles.

Small (5-7mm), reddish-brown, oval, wingless parasites that feed exclusively on human blood. Nocturnal — hides in mattress seams, headboards, baseboards, electrical outlets, and adjacent furniture during the day. Adults can survive 12 months without feeding. Major resurgence in PG accommodations and budget hotels near tech corridors.

Most household spiders in India are harmless and beneficial — they prey on flies, mosquitoes, and other insects. However, two species require caution: the Brown Recluse (Loxosceles) and the Widow (Latrodectus). Most spider concerns are about web aesthetics and arachnophobia rather than actual danger.

India's most common urban bird. Originally a cliff-dweller, the pigeon has adapted perfectly to city buildings — ledges, parapets, AC compressor platforms, and ducts serve as their cliffs. Prolific breeders — 5-6 broods per year of 2 squabs each. Fouling damages paint, blocks gutters, and corrodes metal surfaces.

Slender, reddish-brown wasps that build distinctive open-paper nests under eaves, in shrubs, and around window frames. Less aggressive than yellow jackets but will defend the nest aggressively if disturbed. Painful sting — multiple stings can cause allergic reactions.

Tiny (2mm) yellow-brown ants that form massive multi-queen colonies with up to 300,000 workers. Infamous for 'budding' — when disturbed, colonies split into multiple satellite nests, making DIY spraying counterproductive. Nests in wall voids, behind baseboards, and inside electrical outlets. Major pest in hospitals where they contaminate sterile equipment and seek IV fluids.

Small (3mm) dark-brown to black ant named for its erratic, jerky movement when disturbed. Highly adaptable — nests in soil, wall voids, potted plants, and even electronics. Forms supercolonies that can displace other ant species. Common in Indian kitchens, bathrooms, and balconies, especially in apartment complexes with shared plumbing.

India's largest ant species — workers range from 8 to 15mm. Black or bicolour black-red. Does NOT eat wood but excavates galleries in moist or decaying timber for nesting. A mature colony can hollow out structural beams over 2-3 years. Often confused with termites, but carpenter ants leave clean 'frass' (sawdust) piles outside nest openings whereas termites pack mud.

The primary malaria vector in Indian cities. Pale brown with dark spots on wings, 5-8mm long. Rests at a distinctive 45-degree angle with abdomen pointed up. Nocturnal biter, most active 10pm to 4am. Breeds in clean, sunlit water — overhead tanks, construction sites, puddles, and improperly maintained storm drains.

The most common night-biting mosquito in Indian cities. Brown, 4-10mm long, with a blunt abdomen. Breeds in polluted standing water — open drains, septic tanks, soak pits, and stagnant puddles. The persistent 'whine' at night is a hallmark of Culex presence. Major vector for lymphatic filariasis (elephantiasis) across coastal South India.

The universal urban pest. 6-7mm long, grey with four dark longitudinal stripes on the thorax. Female lays 500 eggs in batches on rotting organic matter — garbage, manure, food waste. Egg-to-adult cycle is just 7-10 days in Indian summer heat. Flies regurgitate digestive enzymes onto food and then lap up the liquid — a primary mechanism of pathogen transfer.

Tiny (3mm) tan-bodied flies with red eyes that plague every Indian kitchen during monsoon and summer. Female lays 500 eggs on overripe fruit, vegetable peels, and fermenting liquids. Egg-to-adult cycle is just 8 days at 28°C — a single overripe banana can produce 200 flies in a week. Major complaint in bars, juice shops, and food-processing units.

Small (7-10cm body plus 7-10cm tail) grey-brown rodent with large ears and small eyes. Exceptional climbers and jumpers — can scale vertical brick walls and jump 30cm from a standstill. Needs only a 6mm gap to enter a building (the width of a pencil). A single female produces 8 litters of 6 pups per year — populations explode fast. Major pest in apartment kitchens, false ceilings, and storage rooms.

India's largest rat species — 30-40cm body plus 25cm tail. Aggressive, burrowing rodent that destroys gardens, foundations, and ground-floor storage. Burrows up to 1m deep with multiple exits, undermining foundations and paving. Unlike house rats, bandicoots live mostly outdoors but invade kitchens at night. Recognised by deep grunting calls and large footprint.

Wingless, tear-drop-shaped insect (12-19mm) covered in silvery scales that give it a metallic sheen. Moves with characteristic fish-like wriggle. Nocturnal, prefers 70-80% humidity and temperatures above 25°C — perfect for Indian bathrooms and kitchens. Feeds on starches and proteins: paper, book glue, wallpaper paste, photos, sugar, flour, dead insects, and synthetic fabrics. Can live 3+ years without reproducing if conditions are wrong.

Small (4-7mm) reddish-brown to black beetle whose larvae tunnel through hardwood for 6-12 months before emerging as adults. Recognised by tiny (1-2mm) round exit holes in wooden furniture and a fine, talc-like frass falling from the wood. Major pest in antique furniture, hardwood flooring, and structural bamboo. Often confused with termite damage but powderpost frass is fine powder, not packed mud.

Native South Asian honey bee, 10-13mm long, brown with pale stripes. Builds parallel wax combs in enclosed cavities — chimneys, false ceilings, wall voids, and tree hollows. Colonies can reach 30,000 bees and persist for years. Ecologically beneficial pollinators, but a colony inside a residential wall becomes a serious stinging hazard and honey-damage issue. Do NOT attempt DIY removal — disturbed bees release alarm pheromone triggering mass stinging.

The most familiar lizard in Indian homes — 7-15cm long, pale pink-grey with translucent skin and distinctive toe pads that allow it to climb vertical glass. Nocturnal, attracted to light fixtures (which attract their insect prey). Mostly beneficial (eats mosquitoes and flies) but their droppings stain walls, contaminate food surfaces, and their eggs can ruin stored food. Heavy populations signal an underlying insect problem.

India's largest non-venomous snake — adults reach 2-3.5 metres. Olive-brown to black with a yellowish underside. Excellent rodent hunter (hence the name) — frequently enters compounds, gardens, and ground floors following rat populations. Often mistaken for cobra due to size and hooding defensive posture when cornered. Non-venomous but a powerful bite requires cleaning. Active during day and dusk, especially after rain.

India's most iconic venomous snake — 1.5-2 metres long, recognised by the distinctive spectacle (glasses) mark on the back of the hood. Found across South India in agricultural land, open scrub, and increasingly in urban gardens near lakes and open spaces. Primarily nocturnal in cities, hunts rodents and toads. Highly venomous — neurotoxic venom causes respiratory paralysis. DO NOT attempt to capture, kill, or approach — call professional handlers immediately.

Highly venomous nocturnal snake, 1-1.8 metres long, with a sleek glossy black body and distinctive narrow white bands. Found across South India in fields, gardens, and sometimes inside homes at night. Often hides in rodent burrows, brick piles, and beneath sacks. The bite is initially painless — many victims sleep through it — but the neurotoxic venom causes progressive paralysis that can be fatal without prompt ASV treatment. THE most medically significant snake in India after the cobra.

Heavy-bodied venomous snake, 1-1.5 metres long, with a distinctive pattern of brown oval spots on a tan-yellow body. Found in agricultural land, open scrub, and urban gardens near lakes across South India. Responsible for the most snakebite deaths in India due to its camouflage, defensive temperament when cornered, and hemotoxic venom that causes severe internal bleeding. Often strikes without warning when stepped on. Coils tightly and hisses loudly — a deep rasping sound unlike any other snake.

Common Indian garden lizard, 30-50cm long including tail, with a crest of spines along the back in males. Colour changes with mood and temperature — brown, olive, to bright orange-red during breeding. Often seen basking on compound walls, fences, and tree trunks. Beneficial insect-eater but their droppings stain walls, and large populations can damage ornamental plants. Males are territorial and aggressive displays can startle children.

Highly adaptable urban bird, 40cm long, glossy black with grey neck and breast. Indian cities support enormous house crow populations — flocks of 200+ are common. Intelligent, opportunistic omnivores that nest in dense trees and on building ledges. Droppings are acidic and corrode paint, metal, and solar panels. Aggressive nest defence during breeding season (Apr-Jun) — they dive-bomb pedestrians near nest trees. Carry ectoparasites and spread Salmonella, E. coli, and histoplasmosis.

Small passerine bird, 15cm long, brown-grey with a black bib in males. Once ubiquitous in Indian cities, populations have declined sharply due to mobile-tower radiation, loss of nesting cavities, and insect decline. Now mostly found in older neighbourhoods with cavity walls, roof vents, and untended gardens. Noisy communal roosts in roof voids and ventilation shafts can stain walls and disturb sleep. Their droppings can carry Salmonella but the primary concern is hygiene around food preparation areas.

Indian pariah dogs — medium-sized, short-coated, tan to brown — are the native free-ranging dog population of South Asia. Pack-forming and territorial, especially near garbage dumps and food markets. Responsible for 99% of rabies transmission in India (20,000+ deaths/year). Aggressive encounters spike during mating season (Aug-Oct) and when pack members are killed or relocated. ABC (Animal Birth Control) rules mandate surgical sterilisation, not culling — but packs near schools and residential compounds require professional management.

Feral and free-ranging domestic cats — 3-5kg, varied coat colours — adapted to urban environments across South India. Solitary hunters but form colonies near food sources. Excellent climbers that enter compounds and rooftops via walls and trees. Hunt rodents, birds, and lizards but their droppings contaminate sandpits, vegetable gardens, and water storage. Toxoplasmosis is the primary human health risk — pregnant women are especially vulnerable.

Ectoparasite of dogs and occasionally humans — 3-5mm unfed, swelling to 12mm when engorged with blood. Brown to reddish-brown, eight-legged, no antennae. The ONLY tick species that can complete its entire lifecycle INDOORS — kennels, dog beds, skirting boards, and floor cracks. Females lay 4,000 eggs after a single blood meal. Heavy infestations cause anaemia in dogs and transmit canine babesiosis, ehrlichiosis, and Rocky Mountain spotted fever to humans.

Tiny blood-feeding insect, 1-3mm long, dark reddish-brown, laterally compressed body (looks side-on). Powerful hind legs allow jumps of 30cm vertically — exceptional for its size. Adult females lay 20-30 eggs per day on the host, which drop off into carpets, bedding, and floor cracks. Eggs hatch in 2-14 days; larvae feed on adult flea faeces. The lifecycle can complete in 2 weeks or take 6 months depending on conditions. Bites cause intense itching and allergic dermatitis.

Large (10-20cm) black scorpion found in damp, dark areas of South Indian homes — bathrooms, drains, beneath stones, and in firewood piles. Nocturnal predator that hunts insects and small lizards. Painful sting but the venom of this species is relatively weak — comparable to a hornet sting. However, identification by laypeople is unreliable, and the smaller Indian red scorpion (Mesobuthus tamulus) is among the most lethal scorpions in the world. ALL scorpion stings require medical observation.

Large (15-20cm) carnivorous myriapod with 21 pairs of legs, orange-brown body with dark bands on each segment. Nocturnal predator found in damp areas — bathrooms, drain chambers, beneath pots, and in stored cardboard boxes. Fast runner (up to 50cm/sec). Bites with modified front legs (forcipules) — venom is painful but not life-threatening to adults. Sensitive to humidity — peaks during monsoon and in poorly ventilated ground-floor flats.
