In the US alone, we spend greater than $2.5 billion a yr making an attempt to rid our houses of cockroaches and different pests—however a brand new examine says a few of us could also be doing all of it incorrect. The peer-reviewed examine examined the effectiveness of baits, gels laden with insecticide, and bug bombs, units that “fog” a room with an insect-killing aerosol. For at the least one pest, the frequent German cockroach (Blattella germanica), bombs don’t work, says the examine, however baits do.

Scientists set off 4 sorts of bombs and positioned two sorts of baits in 30 infested houses in Raleigh. Twenty houses obtained one of many 4 bombs and 10 obtained one of many two baits. The scientists counted the variety of cockroaches earlier than remedy and after, as soon as at 2 weeks and as soon as 1 month later. In each dwelling that had been bombed, cockroach numbers stayed the identical, the researchers report this week in BMC Public Well being. With one bait, populations dropped by greater than half after 2 weeks; with the opposite, they plummeted by greater than 75%. Numbers went down much more after the complete month.

Researchers additionally examined the quantity of insecticide residue left behind by the bombs. Even earlier than the remedies, the middles of counter tops, flooring, and different areas closely trafficked by people (however not bugs) had residue; simply hours after bomb use, these ranges shot up 600%. Some residue caught round even a month later.

Baits price extra, however given the ineffectiveness of the bombs, the researchers say they’re nonetheless the most suitable choice. As for bombs, the researchers name them “inappropriate” for dwelling pest management, going as far as to query whether or not they need to nonetheless be bought for this use.
