Common Household Pests in Kenya
Cockroaches
Signs of a Cockroach Infestation
- Presence of live cockroaches: Sightings of live cockroaches scurrying in the dark corners of the home are a clear indication of an infestation.
- Fecal droppings: Cockroach feces resemble small, dark pellets and are often found in areas where cockroaches frequent, such as kitchens and pantries.
- Egg casings: Cockroach egg cases, known as oothecae, are commonly found in hidden cracks and crevices and indicate a breeding population.
- Musty odor: A strong, musty odor may be present in areas with a significant cockroach infestation, caused by the insects’ secretions.
Prevention Tips
- Sanitation: Keep the home clean and free of food debris, crumbs, and spills, as cockroaches are attracted to food sources. Regularly clean and disinfect kitchen surfaces and appliances.
- Sealing entry points: Seal cracks, crevices, and gaps around doors, windows, and pipes to prevent cockroaches from entering the home.
- Using baits or traps: Place cockroach baits or traps in areas where cockroaches are likely to hide, such as under sinks, behind appliances, and in cabinets. These traps can help reduce cockroach populations and monitor infestations.
Bed Bugs
Bed bugs are small, reddish-brown insects that feed on the blood of humans and animals. They are typically nocturnal and hide in cracks and crevices during the day.
Signs of a Bed Bug Infestation
- Bite marks: Bed bug bites often appear as red, itchy welts on the skin, typically in a cluster or linear pattern. However, not everyone reacts to bed bug bites, so the absence of bites does not necessarily mean an absence of bed bugs.
- Blood stains: Smears or stains of blood on bedding, mattresses, or furniture may indicate bed bug feeding activity.
- Fecal spots: Dark brown or black spots on bedding, mattresses, or walls, which are bed bug excrement, may be visible in areas where bed bugs congregate.
- Musty odor: A strong, unpleasant odor resembling coriander or mold may be present in rooms with a severe bed bug infestation.
Prevention Tips
- Regular inspection: Conduct routine inspections of bedding, mattresses, and furniture for signs of bed bugs, especially after traveling or hosting guests.
- Laundering bedding: Wash bedding, linens, and clothing in hot water and dry them on high heat to kill any bed bugs or eggs present.
- Using mattress encasements: Encase mattresses and box springs in bed bug-proof covers to prevent bed bugs from infesting these items and make it easier to detect and treat infestations.
Ants
Signs of an Ant Infestation
- Trails of ants: Visible trails of ants moving in and out of buildings, particularly near food sources or entry points.
- Ant nests: The presence of ant nests, which may be located indoors in wall voids, under floors, or outdoors in soil, mulch, or debris.
- Frass or debris: Accumulations of ant frass (fecal matter) or debris near nest sites or foraging areas.
- Damage: Damage to wooden structures or furniture caused by carpenter ants excavating galleries for nesting.
Prevention Tips
- Sealing cracks and crevices: Seal gaps, cracks, and entry points around doors, windows, and utility penetrations to prevent ants from gaining access to buildings.
- Eliminating food sources: Store food in tightly sealed containers, clean up spills promptly, and maintain cleanliness in kitchens and dining areas to reduce ant attraction.
- Using ant baits or repellents: Place ant baits or apply non-toxic ant repellents near entry points or areas where ants are active to deter their presence and control infestations.
Rodents (Rats and Mice)
Signs of a Rodent Infestation
- Droppings: The presence of rodent droppings, which vary in size and shape depending on the species.
- Gnaw marks: Gnaw marks on wood, plastic, or electrical wires, indicating rodent activity.
- Nesting materials: Shredded paper, fabric, or insulation used by rodents to build nests in hidden areas.
- Grease marks: Smudge marks along walls or baseboards caused by rodents repeatedly rubbing against surfaces.
Prevention Tips
- Sealing entry points: Close gaps, cracks, and holes in walls, foundations, and around utility lines to prevent rodents from entering buildings.
- Proper food storage: Store food in rodent-proof containers made of metal or heavy plastic and clean up crumbs or spills promptly to reduce attractants.
- Using traps or rodenticides: Place snap traps or bait stations in areas of rodent activity and use rodenticides cautiously and according to label instructions to control infestations effectively.
Mosquitoes
Signs of a Mosquito Problem
- Presence of Adult Mosquitoes: Seeing adult mosquitoes buzzing around indoors or outdoors, particularly during dusk and dawn when they are most active.
- Mosquito Bites: Itchy, red welts on the skin caused by mosquito bites, often occurring in exposed areas such as arms, legs, and neck.
- Breeding Sites: Identification of potential mosquito breeding sites, including stagnant water sources such as clogged gutters, flowerpots, and birdbaths.
Prevention Tips
- Eliminating Standing Water: Regularly emptying containers, unclogging drains, and maintaining proper drainage to remove potential mosquito breeding sites.
- Using Mosquito Nets or Screens: Installing mosquito nets over windows and doors or using bed nets to prevent mosquitoes from entering living spaces.
- Applying Insect Repellents: Using EPA-approved insect repellents containing DEET, picaridin, or oil of lemon eucalyptus to deter mosquitoes when spending time outdoors, especially during peak biting times.
Termites
Signs of a Termite Infestation
- Mud Tubes: Presence of mud tubes along walls, foundations, or wooden structures, which termites use as sheltered pathways between their nests and food sources.
- Wood Damage: Hollowed-out or damaged wooden structures, furniture, and flooring, often accompanied by maze-like patterns on the surface.
- Swarmers: Appearance of termite swarmers, winged reproductive termites, especially during the spring or after rainfall, indicating an established colony nearby.
Prevention Tips
- Regular Inspection: Conducting routine inspections of the property for signs of termite activity, paying attention to areas prone to moisture and wood-to-ground contact.
- Moisture Control: Addressing leaks, improving ventilation, and maintaining proper drainage to reduce moisture buildup, as termites are attracted to damp environments.
- Using Termite Barriers or Treatments: Installing physical barriers such as metal mesh or chemical treatments like liquid termiticides around the perimeter of the property to deter or eliminate termites.
Flies
Signs of a Fly Infestation
- Presence of Adult Flies: Seeing an unusually high number of flies indoors, especially around food preparation areas, garbage bins, or drains.
- Larvae or Eggs: Discovering fly larvae or eggs in moist or organic materials such as garbage cans, drains, or compost bins.
- Foul Odors: Foul or rotting odors emanating from areas where flies breed or congregate, indicating the presence of decaying organic matter.
Prevention Tips
- Proper Waste Management: Seal garbage bins tightly, dispose of food waste promptly, and clean up spills or crumbs to eliminate potential breeding sites for flies.
- Screening Windows and Doors: Install screens on windows and doors to prevent flies from entering the home while still allowing for ventilation.
- Using Fly Traps or Insecticides: Place fly traps or fly paper near areas where flies are commonly found, or use insecticides labeled for fly control to reduce fly populations indoors. Regular cleaning and sanitation are also essential for fly prevention.
