Forget mosquito netting and bug spray. malaria-spreading blood-suckers: introduce spermless males into the population.

Female mosquitoes who mated with these genetically altered males produced sterile eggs that didn't hatch, according to the paper published in the journal Proceedings of the National Academy of Sciences. Researchers from Imperial College London sterilised male mosquitoes by genetically modifying them to neutralise a gene required for sperm production.

Female mosquitoes would then unknowingly mate with the modified males and fail to produce any offspring.
