Many types of fleas live as parasites on various animals. Pet fleas usually do not linger for long on the skin of man, with two exceptions – hen flea (echidnophaga gallinacea) and sand flea, which is found in Africa, the Caribbean area and the southern part of the United States. Fleas jump very well, so the individual bites on human skin can be attributed to animal fleas (usually dog or cat) that have temporarily left their hosts.
Fleas deposit eggs in bedding, and after a week larvae penetrates from them. Developed fleas can then live in bedding, feeding on animal hosts, and occasionally on man.
Flea bites, the consequences of sucking blood, cause intense irritation that lasts for up to two days. The infestation of fleas occur in all parts of the world, but are most common in terms of direct contact with domestic animals and poor hygienic conditions.
What to do?
Prevent the infestation with spray or flea powder, or wash your pet with shampoo and sprinkle his “bed” with spray. If you suspect that a source of infestation is in your own bed, on the furniture or carpets, sprinkle them an anti-flea spray and rub your skin with insecticide. In serious cases it would be appropriate to invite experts for disinsection to get rid of fleas in the house.
The health centers there are hygienists who can perform disinsection when needed; at the National Institutes of Health, there are departments for disinfection, pest control and decontamination where you can get advice and help on how to get rid of insects.
