Cockroaches are often found in areas where food preparation occurs and bathrooms because they favor warm, humid areas that are close to food and water. The most common indoor species, the German cockroach, also reproduces the fastest, producing an egg case with as many as 30 young every few weeks. They have also proven to be very resilient, making pest control a challenge.
Cockroaches can contaminate food items, as well as cooking and eating utensils. They also destroy paper goods and fabrics and can spread disease, including staphylococcus, streptococcus, typhoid, dysentery, the hepatitis virus and coli from bacteria.
The heating process is effective in stopping the spread of cockroach populations by raising the core temperature of the room to the appropriate level and sustaining it for a period of several hours. This approach kills the cockroaches, and any mold spores they potentially brought with them. Future infestations are prevented by drying the moist areas where the cockroaches nest. The process can be accomplished in as little as one day and leave the structure bug-free and disinfected.
