简介
To get rid of Houston fleas and stay ahead of them, this is what you should know: Adult fleas are small, black to brown-black creatures without wings. They are 1-4 mm long with laterally flat bodies and strong spring-like legs capable of leaping several inches high. Fleas can survive several months without a blood meal if no host is available and adults can live for many years. People entering vacant homes or buildings are sometimes attacked by hungry fleas awakened from hibernation by the walking vibration and the hosts' emission of detectable carbon dioxide. Reproduction Cycle Females require a blood meal to lay their eggs. Fleas cycle through stages from egg to larvae, pupae and then adult. The eggs from the flea species that commonly attack man generally take 10-21 days to hatch out depending on the temperature and humidity present. In a cold environment the hatch cycle can take several weeks to complete. Eggs are laid on the host but are not attached and commonly fall off ending in nearby cracks and crevices, on bedding, under edges of carpeting and in pet boxes or kennels. The female fleas produces 4-8 eggs after each blood meal and can lay typically hundreds of eggs during her life span.
