MQUSEMATS indicates whether the household uses "mats" to avoid mosquitoes. Such mats are presumably imbued with mosquito repellent. Some commercial brands of mosquito repellent mats use a butane cartridge to heat a small mat soaked in insecticide and thus prompt the release of insecticide.
The information in MQUSEMATS is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
