Heat treatment is offered by some pest control companies to try and eradicate insects such as bed bugs, moths and fleas from homes. Typically, heaters are either installed directly in the room(s) being treated, or hot air is blown into the room(s) from an external unit using flexible ducting.
The problem with this technique is that as the insects feel the temperature gradually increase from the heat source they attempt to move away. They’ll try and move from their hiding places to cooler areas. Unless all possible escape routes have been blocked off the insects are dispersed. This is exactly what an effective control should be avoiding. It will only be a matter of time before an infestation is re-established – but longer than the 3 months most pest control companies guarantee their treatment for!
With bed bugs especially, which hide in small cracks around the perimeter of a room, they can move through gaps in floorboards, behind skirting boards etc. Hiding in places such as these they’re less likely to be killed off as the heat won’t reach all the voids within a building.
The contained environment our pest control team uses makes it impossible for insects to escape the heat.
The other issue with heating entire rooms is that wooden furniture and woodwork can easily become damaged/warped as a result of the quick changes in temperature. This isn’t the case using our contained environment because these items would never be placed inside. Instead they would be thoroughly checked by our pest control team and treated either with chemical spray or with steam. Neither of these would result in damage.
