Do humans really eat insects without knowing?

Many pacific islands were without insects or flies before sailing ships arrived. The people on them lived just fine. In the 1920s and 1930s many areas in the southern part of the United States poured oil over their swamps and temporally got rid of their mosquitoes when the United States wiped out malaria. When that stopped, the mosquitoes came back but the malaria did not.

Since so many insects eat plants and arachnids eat insects, without arachnids, we would starve. No. we could not live without them.
