What size are Bed Bugs?

Well it depends. Bed bugs grow significantly though their life cycle and can start off quite small from the nymph stage before becoming adult bed bugs. After feeding on human blood, they can also swell to about twice normal bed bug size during their life cycle. Adult bed bugs have flat bodies compared to the babies. Also they lay eggs which are a bit harder to see and much smaller, sometimes found on the skin.

Treatment options for bed bugs

If you do find any, you will need to treat the infestation thoroughly to remove of all the bedbug eggs, nymphs and adults, to prevent them returning. For a light infestation, you may get away with just washing all the bed coverings.However, for a bad infestation, you might need to throw all your bedding in the bin and replace your mattress too. If it is a devan bed, these insects can also live inside the bed, so best to replace everything if necessary. It is also well worth checking all your clothing as a bed bug can transport itself on clothes too. Also, it may be worth while calling in a professional pest control company who have experience with insects infestation. Find out about the eco defense bug spray.
