Bed bugs are a type of insect that feeds on blood typically at night. Their bites can be noticeable but cannot be relied upon as conclusive evidence alone but can have physiological effects and allergic reactions. Bed bug feeding at night typically wait until the host is settled and asleep, using the exposed members of the body legs, arms, neck.
There are two types of bed bugs the common bed bug and the tropical bed bug. The common head is rounder but he tropical is more pointed. They start as eggs and are the same shape when emerging translucent and by feeding and molting can grow to 4-5mm. At nymph stage they are hard to see but after feeding they stay a reddish hew for the rest of their lives. Normal feeding happens once every three days but when no source is available can go months without feeding and the eggs can last for up to 2 years. Most bed bugs can be found near a host but 30% can be up to 15 feet away traveling about 4 ft a minute to feed across carpeting.
The spread of bed bugs maybe attributed travel and the restriction of organophosphate pesticide use and the reduction of pesticide being used in general. Most bed bugs have a high resistance to materials on today’s market and can be difficult to control by a single chemical treatment. Early detection is hard in small numbers but they live about four to six months average and a female can lay up to 200 to 300 eggs in their lifetime adult stage in about 5 weeks. Larger number's can be more visible and found readily on the bed around the head and feet of the bed. There are advance methods of monitoring but after an initial treatment and 60 days of monitoring can have a 97% rate of success.
Treatment can vary in scope and cost and while chemical treatment is still an option many have chosen to manage using heat. Heat is the most effective way with the fastest results with less stress in preparation of a home. While chemical treatments require more preparation on the customer it also leaves a higher margin for error.
Best to get an initial inspection and determine the severity, how the bed bugs were introduced into the home. All bed bugs have to be carried and introduced to individual homes but in some sever infestations in multi unit housing can spread to other units.
