I found out myself this does kill bed bugs instantly. From my personal experience by trial and error, its my opinion that a cheapest can of regular Raid Ant & Roach bug spray does kill Bed Bugs on contact. I heard that bed bugs are becoming pesticide resistant but the bed bugs at my neck of the woods are not immune to regular Raid Ant & Roach spray. I got rid of bed bugs in my room with a can or two of this sprayed all over in the nooks and crannies. How I know this product works is that one time found a bed bug crawling on the wall, I sprayed it this can and instantly the bed bug fell off and died on the spot.
Adult bed bugs are light brown to reddish brown, flattened, oval shaped, and have no hind wings. Bed bugs have segmented abdomens with microscopic hairs that give them a banded appearance. Adults grow to 4–5 mm long and 1.5–3 mm wide. Newly hatched nymphs are translucent, lighter in color, and become browner as they molt and reach maturity. A bed bug nymph of any age that has just consumed a blood meal has a bright red, translucent abdomen, fading to brown over the next several hours, and to opaque black within two days as the insect digests its meal. Bed bugs may be mistaken for other insects, such as book lice, small cockroaches, or carpet beetles; however, when warm and active, their movements are more ant-like and, like most other true bugs, they emit a characteristic disagreeable odor when crushed. Bed bugs use pheromones and kairomones to communicate regarding nesting locations, feeding, and reproduction. The lifespan of bed bugs varies by species and is also dependent on feeding. Bed bugs can survive a wide range of temperatures and atmospheric compositions. Below 16.1 °C (61.0 °F), adults enter semihibernation and can survive longer; they can survive for at least five days at −10 °C (14 °F), but die after 15 minutes of exposure to −32 °C (−26 °F). Common commercial and residential freezers reach temperatures low enough to kill most life stages of bed bug, with 95% mortality after 3 days at −12 °C (10 °F). They show high desiccation tolerance, surviving low humidity and a 35–40 °C range even with loss of one-third of body weight; earlier life stages are more susceptible to drying out than later ones. The thermal death point for C. lectularius is 45 °C (113 °F); all stages of life are killed by 7 minutes of exposure to 46 °C (115 °F). Bed bugs apparently cannot survive high concentrations of carbon dioxide for very long; exposure to nearly pure nitrogen atmospheres, however, appears to have relatively little effect even after 72 hours.

Bed bugs are obligatory hematophagous (bloodsucking) insects. Most species feed on humans only when other prey are unavailable. They obtain all the additional moisture they need from water vapor in the surrounding air. Bed bugs are attracted to their hosts primarily by carbon dioxide, secondarily by warmth, and also by certain chemicals. Bedbugs prefer exposed skin, preferably the face, neck, and arms of a sleeping person. Bedbugs have mouth parts that saw through the skin, and inject saliva with anticoagulants and painkillers. Sensitivity of humans varies from extreme allergic reaction to no reaction at all (about 20%). The bite usually produces a swelling with no red spot, but when many bugs feed on a small area, reddish spots may appear after the swelling subsides. Although under certain cool conditions adult bed bugs can live for over a year without feeding, under typically warm conditions they try to feed at five- to ten-day intervals, and adults can survive for about five months without food. Younger infants cannot survive nearly as long, though even the vulnerable newly hatched first instars can survive for weeks without taking a blood meal. How to kill bed bugs.
