Bed Bugs
Once bedbugs sense that activity is reduced and the victim may be asleep, they come out from hiding to feed. The longer the bugs live in your bedroom, the harder it is to get rid of them.
Bedbugs can squeeze into nearly any crevice; tiny cracks in plaster or even the narrow seam of electrical outlet plates are no barrier to these hungry little parasites. They can crawl freely on nearly any surface, navigate while inverted, and have been observed falling up to ten feet without being harmed.

Fleas
Fleas mainly live on host, but the eggs hatched by them are left on the host and the host's bedding. The eggs that are laid on the host drop down and accumulate on beds, clothes, carpets and the under areas of many furniture. In about one to two weeks, the eggs hatch and larvae is born. These stick to the carpets and bedding for a stretch of 200 days. Gradually the larvae transforms into legless pupae, which remain like that for a whole year. If conditions are favorable then the pupae transform into fleas.
