Bed bugs, since they’re elusive, can be a threat. Even trained professionals have problems getting them exterminated. When you believe that you have bed bugs because of frequent bite marks on the skin, locate any evidence immediately and correctly determine that the insect is a bed bug. Check Bed Bug Inspection.
It is critical that you conduct a thorough room inspection to locate all the harbor sites and determine the source and extent of the infestation. The bed is the first place to search, because the pests tend to stay near the resting place of the host.
While inspecting you need to know what to look for and you need some tools. In order to correctly identify the pest you must also understand the basic biology.
The ecology of bed bugs
The bed bug eggs are about 1 mm long and about 0.5 mm high, with an egg cap (operculum). The eggs are dark and opaque in colour.
The bug on the adult bed is reddish-brown in colour. This has a shape that is oval and dorso-ventrally flattened when not fed. The insect is wingless and with piercing mouthparts of about 5-7 mm in length.
When unfed it is light yellow-brown in colour, but changes after feeding to a darker reddish-brown color.
It has a short broad head with prominent eyes, a pair of 4 segmented antennas in the ventral groove and 3 segmented proboscises. It is very distinctive, and can be immediately identified. Nymphs are smaller versions of thinner cuticulated adults. Nymphs are translucent in color and size range from 1.3 mm to 5 mm as they pass through five instars.
Inspect the bedding and matelas. Pay careful attention to the edges of the wall and dark spots. Pour alcohol onto a piece of cotton wool to test dark spots on the mattress and stains. This is blood stain if the mark dissolves with a reddish-brown color. Continue looking until you find bugs to bed.
Check the mattress tufts, seams and holes, check the material under buttons and folds, check the piping material sown to the edges and the handles and labels underneath.
If the mattress is on a base divan check the edge of the material below the base and the hollow caster legs. Look under the spring of the mattress and box, and between the frame and floor. Check inside vinyl plastic seams and rips which cover the mattress.
Spring test of the box
Lift and check gradually the positions where the spring box sits on the bed frame to prevent spreading the bed bugs.
Remove the spring box from the bed frame, and inspect below.
Inspect inside the material fold on top of the box spring surface. Check along seams and areas where you tackle the material to the frame. Turn the box spring gently, remove the thin layer of cloth at the underside and inspect it.
To inspect between box spring and bedframe, use the flashlight, the crevice tool, and magnifying glass. Inspect staples and tacks at the furniture below and above. Flush the pests with the flushing agent (e.g. pyrethroids) from the hiding place. Place double-faced tape on the furniture ‘s underside to catch bugs escaping from beds.
Inspection of bed-frames
Inspect where the joints in the frame intersect with the help of a crevice tool. Turn the frame gently over, and check the underside. Examine screws and nail holes with caution.
Dismantle the pillow, and test the joints. Replace the headboard, and check it. Check on the headboard along the joints and on the behind the headboard wall.
Also for qualified professionals the bed bugs are hard to handle. Many domestic insecticides that are registered to treat the pests are ineffective.
