Full Answer

To kill roaches with bleach, fill a spray bottle with bleach and water and spray the insects directly. Use bleach with caution, because it can easily discolor fabrics and upholstery. Bleach is also corrosive and can damage metal when used consistently. For instance, cleaning drains with bleach may damage the pipes and result in the need for repairs. Typically, bleach is used sparingly to treat very minor infestations.

Non-porous surfaces can safely be sprayed with bleach. For instance, most bathtubs, kitchen counters and vinyl floors can be exposed to bleach without damaging the material. A standard cleaner that contains a small amount of chlorine bleach can be used in these areas to kill roaches. Bathrooms and kitchens can also be cleaned with a bleach solution to kill bacteria commonly carried by roaches. Bleach is typically ineffective for treating serious roach infestations. Serious roach infestations often require a professionally applied insecticide or bait system to eliminate the pests from the home.

To reduce wear on drain pipes and other fixtures in the home, use a diluted bleach solution infrequently. Hot, soapy water is also an alternative to bleach that kills roaches effectively without causing damage to the items in the home.

    How does roach spray work?

    A:

    Pesticides can kill roaches and other pests many ways, but the most common method of elimination is through disruption of the insect's nervous system, according to the Environmental Protection Agency. Most roach sprays contain nerve-destroying agents similar to those used in chemical weapons, but they are used in much smaller doses to prevent harm to pets and humans, according to Wessels Living History Farm.

    What are white roaches?

    A:

    Contrary to popular belief, there are no white or albino cockroaches. The white color is actually caused by the splitting and shedding of the cockroach's cuticle, which is its exterior casing. The cockroach sheds this cuticle during molting from a nymph into an adult.
