If you have dogs or cats, check them first. Use a fine-toothed flea comb around the neck and tail. Look for live fleas or black flea dirt (specks that turn red on a damp tissue). Wash pet bedding and check rugs and carpets for flea dirt at floor level. If you find evidence here, fleas are the confirmed source.

If you don't have pets or the pet check was negative, inspect your mattress seams, bed frame joints and headboard with a flashlight. Look for small dark spots (bed bug droppings), pale shed skins (exuviae) or live bugs 4–5mm long. Bed bugs are reddish-brown, flat and oval-shaped. No pet connection + upper-body bites during sleep = strong indicator of bed bugs.

Yes — a home can be infested with both simultaneously, although it is uncommon. Pet owners who recently travelled, purchased second-hand furniture or moved into a property may encounter both pests. Importantly, the control methods for fleas and bed bugs are completely different: flea control requires treating pets and their environment, while bed bug elimination requires heat treatment, targeted insecticides and physical exclusion of hiding spots. A professional inspection will determine which pest (or both) is present and recommend the correct treatment strategy.

Yes. Fleas can be introduced into a home without a resident pet. The most common routes are: rodents in wall cavities or beneath the floor (rat fleas will bite humans readily), stray animals that entered the property, or a previous occupant's pet infestation left in carpets. Flea pupae can lie dormant for up to 6 months and emerge when they detect vibration and warmth from a new occupant. Lower-leg bite clusters with no obvious cause warrant a professional inspection to rule out rodent-linked fleas.

No — bed bugs can establish themselves anywhere they can hide within crawling distance of a sleeping host. This includes sofas, upholstered chairs, wooden furniture joints, electrical outlet covers, behind picture frames, under carpeting at the room perimeter and in luggage. In heavy infestations, they disperse into wall cracks and adjoining rooms. The term "bed bug" reflects where they are most commonly found in early-stage infestations, not a limitation on where they can survive.

Heat treatment is regarded as the gold standard for bed bug elimination because it kills all life stages (including eggs) without leaving toxic residues. Temperatures above 50°C are lethal to all bed bug life stages. For Singapore's high-density housing, professional heat treatment combined with targeted residual insecticide application to cracks and crevices provides the most complete solution. DIY aerosol sprays are ineffective for established infestations because bed bugs hide in areas that sprays cannot penetrate and eggs are resistant to most contact insecticides. Always use an NEA-licensed pest management professional for bed bug treatment.
