Bed bugs hide in cracks, crevices, and fissures in wooden furniture like old wooden cots, chairs, deewans, drawers, wall mounted furniture boxes and their drawers, wooden wall hangings, electrical switch boxes especially old wooden type, and other such items. They would come out in night and suck the blood of humans and then disappear back in those deep places. They are a big nuisance and do not get killed easily with just spraying of some home remedies as it does not reach them due to their deep hiding places. Kerosine would be partially effective.
To tackle their menace sometimes it would be necessary to dismantle the old furniture and clean all the cracks where chances of having bed bug eggs are existing. Until these eggs are destroyed we cannot get the real rid of bed bugs totally. The professionals suggest to use vacuum cleaner to suck the dust and bed bug eggs from such deep places. Another thing is all the furniture is to be cleaned in this way as even if a few of them remain there they would soon multiply. A good vacuum cleaning job is a pre-requisite before an insecticide treatment as that would facilitate good insecticide penetration in the cracks and small joints where gaps are generally there in the furniture. The dust and garbage collected in the vacuum cleaner is to be disposed outside the house in the main garbage collection area. In old furniture the cushions and mattresses are to be checked for any torn out places or holes as that also becomes a place for hiding of these bed bugs. Sometimes the box spring loaded mattresses are torn out and that becomes a hiding place for these bugs. In such cases either the mattress is to be replaced or it is to be encased in a completely sealed cover which are available in the market.
Bed bugs are small insects generally having sizes 6-8 mm and as they are flat in their shape that enables them to enter the cracks very swiftly and they disappear there in no time. Professional insect controllers use sometimes insecticide Aerosol such as CB-80 or PT 565 to flush the hiding bugs out of their hiding places just to find out the various areas of their hiding. This insecticide is used to displace them from their hiding places as they run out to save their life from this poison. It finally kills them on contact.
Once the basic cleaning of the furniture and other suspected places is done then one has to get some bug killing Aerosol from the market and spray it in all the places especially the cracks and crevices where some of the bugs would be still hiding. Some of the commercial Aerosols available for this purpose are like Spectre 2 SC, CrossFire Bed Bug Insecticide Concentrate, Temprid FX, D-Fense NXT, Cimexa Dust, Crossfire Aerosol, Bedlam Plus Aerosol, and Phantom Aerosol. You have to go to an insecticide shop and ask him a specific bed bug killer as he might not be having exactly the same name Aerosol but would provide the equivalent one from his inventory.
