I've been having a lot of roach and fly problems in my house recently. I've also swatted many of them. I have noticed that I don't see any blood when I swat them dead. Just out of curiousity, I want to know if insects have any blood at all, and if they do, how come they don't bleed when they get swatted dead?

They don't have blood like we do but they do have internal fluids. Surely you must see a gooey spot when you squish them. Roaches have pretty hard exoskeletons so its possible to kill them without them oozing everywhere.

Insects have blood, but it's not like our blood. Our blood is red because it has hemoglobin, which is used to carry oxygen to where it is needed in the body. Insects get oxygen from a complex system of air tubes that connect to the outside through openings called spiracles. So instead of carrying oxygen, their blood carries nutrients from one part of the body to another. They do bleed when they are hurt, and their blood can clot so they can recover from minor wounds.

Yes, insects do have blood, but it is nearly
colorless, so you don't notice it when you swat
it. A few insects do have red blood, but not the
ones you mention. I have sometimes noticed
a red color when swatting a fly, but this may be
from something they have eaten, rather than the
blood.

insects are special organism in that they do not have a closed circulation like mammals and other higher organisms have. u must have heard that a cockroach has 13 hearts. their respiration is thru the external surface something equivalent to the skin so their fluid(blood equivalent) does not ooze and appear red

Insects belong to the Phylum Arthropoda. They are the group of organisms having 'jointed legs' unlike others. 'Hemoglobin', a respiratory pigment present in the blood of higher animals, is responsible for its red color. But in insects and other lower groups of animals, 'hemocyanin' (instead of hemoglobin) plays the role of oxygen carrier. This pigment imparts a bluish white color to the blood of insects. There may be other pigments too. "Unlike the hemoglobin in red blood cells found in vertebrates, hemocyanins are not bound to blood cells but are instead suspended directly in the hemolymph." The circulatory system in higher animals is of closed type, i.e, the blood flows within the blood vessels (Arteries and veins). But in invertebrates, it is of open type, i.e, the blood remains suspended in the body cavity (which, in their case, is known as haemocoel). Arteries and veins are absent in them.

Insects dont have BLOOD, so they dont bleed.
