The Advante Blackhole traps other flying insects besides mosquitoes. The Photo-catalysis effect in TiO2 is a disintegration process that uses light-energy to create CO2 and H2O. In other words, this product also sterilizes foul smells and purifies the air. The Advante Blackhole is an environmentally friendly pest control product because it’s smokeless, odourless and requires no chemicals. It’s also safe for humans and pets too.
