Cockroaches may become pests in homes, schools, restaurants, hospitals, warehouses, offices, and virtually in any structure that has food preparation or storage areas.
People are repulsed when they find cockroaches in their homes and kitchens. Cockroaches (especially the American cockroach, which comes into contact with human excrement in sewers or with pet droppings) may transmit bacteria that cause food poisoning (Salmonella spp. and Shigella spp.). German cockroaches are believed to be capable of transmitting disease-causing organisms such as Staphylococcus spp., Streptococcus spp., hepatitis virus, and coliform bacteria. They also have been implicated in the spread of typhoid and dysentery.
Indoor infestations of cockroaches are an important source of allergens and risk for asthma among some populations. The levels of cockroaches and allergens are directly related to cockroach density, housing disrepair, and sanitary conditions.
Insecticides are most effective in controlling cockroaches when combined with sanitation and exclusion practices that limit the cockroach’s ability to establish or reinvade; chemical control alone will not solve the problem.
If insecticides are used, they must always be used with extreme care. Indoor chemical control is warranted only if the cockroach population is established, but not for an incidental intruder or two.
How to prevent Cockroaches
Areas with food, water and dark spaces to hide are ideal environments for Cockroaches to live.
Here few prevention tips for securing your property:
- Keep areas clean and tidy - Clean all surfaces thoroughly to remove any food residue. Try and not leave dirty dishes and utensils in the sink.
- Keep bins covered, clean, and emptied regularly. Areas such as top or beneath your refrigerator are warm and food collect their, attracting Cockroaches, so clean these areas regularly
-Proofing and Repair - seal gaps around doors, windows, and where utility lines enter to prevent entry. If possible, repair any leaks beneath the sink, and on the sink top, immediately, thus cutting a potential water source
For crack and crevice treatments, gel baits can be very effective. Apply gel using a bait gun or syringe in small dabs in cracks and crevices where cockroaches will find it. While they are fresh, bait gels are very effective when placed in locations where they will be found by cockroaches.
To remain effective, however, the gels need to be reapplied frequently. Bait gels dehydrate in about 3 days when left in open air. Gels are most effective if applied in indoor areas.
