The swallows are back in Rome, a bit later than usual this year, and so is the annual campaign against tiger mosquitoes, with the first warning from the city's hygiene and health department against these unpleasant insects. Residents are being asked to get rid of stagnant water on their terraces and balconies, to clean their gutters, to disinfect drains in private courtyards and to find gold fish for their fountains. Special teams will be spraying 700,000 drains throughout the city with special disinfectant by 30 June, 650 monitoring stations will be set up around Rome and 500 mosquito traps will be operational in keys areas. The areas of Rome most at risk are Parioli, the Via Cassia, Ostia Lido, Cecchignola, Colli Portuense and Boccea.
