Warren puts mosquito control briquettes in catch basins

The City of Warren has once again taken efforts to control mosquitoes.

Mosquito control briquettes have been applied to nearly 18,000 catch basins in the Detroit suburb.

Warren says it's the first application of the mosquito repellants this year by public works employees. The briquette works by killing mosquito larvae before they grow into biting adult pests. The device floats in the water and slowly releases the compound, which settles in the water and kills the mosquitoes.  

They last for about a month, and the city says they'll put more briquettes in again in August. 

Mosquitoes can breed in catch basins, tire swings, buckets and anything else that holds standing water.

Warren Mayor James Fouts says the control measures are aimed at protecting residents from West Nile virus and other illnesses that can be contracted from mosquitoes and ticks.

Health officials say most people infected with West Nile virus don't develop symptoms. Sometimes, though, a mild illness results 1 to 2 weeks after exposure. Those symptoms can include fever, headache, body aches, skin rash, and swollen lymph nodes.
