According to Foodsafety.gov, you can store hard boiled eggs in the fridge for up to a week in their shell. Most say that if you peel the eggs, you should eat them within a few days. But if you've watched my meal prep video where I make soft boiled eggs ahead of time, you'll see I frequently store peeled eggs for up to three days no problem. Do what you feel comfortable with.
To some people, bed bug eggs look like sesame seeds and somewhat hard. However, no literature clearly defines the texture of bed bug eggs that way. From what people have experienced in their homes and seen with their naked eyes, bed bug eggs are not somewhat hard and neither do they look like sesame seeds.
These are what bed bug eggs look like that have hatched. New eggs are not transparent, white, and sticky and look like rice. This is what bed bug poop looks like and is dried blood that was excreted. A baby bed bug (1st instar) is only a millimeter in size and almost transparent making it very easy for them to blend into the background.
The bed bug's body size also varies through their lifetime. Nymphs or juvenile bed bugs range from the size of a bed bug egg (0.09 inches, 2.5mm) to the size of full adult bed bugs at ( 0.18 inches, 4.5mm). For reference, 0.1 inches is slightly over the thickness of a quarter. Adult bed bugs are approximately the size of an apple seed.
Carpet Beetle Eggs. Carpet beetles undergo complete metamorphosis, passing through the egg, larval and pupal stages before developing into adult insects. Varied or black carpet beetles produce only one generation each year, while other species are capable of producing up to four generations per year.
