Non-Food Items. Most non-porous items (like dishes and utensils) can probably be cleaned of roach debris (you'll do it later). Porous items like paper goods become a health hazard when soiled by roaches. So definitely throw those items out.
The best way to get rid of roaches fast is to sanitize your home, eliminate hiding spots and stagnant water, store food in airtight containers, and use glue strips, bait, boric acid, or liquid concentrates.
Hiring an exterminator is probably what you'll have to end up doing. Because roaches are so resilient, it is nearly impossible to clear out an infestation yourself. Some methods can cull their numbers and keep them out of certain areas of your house.
Roach Repellents
Peppermint oil, cedarwood oil, and cypress oil are essential oils that effectively keep cockroaches at bay. Additionally, these insects hate the smell of crushed bay leaves and steer clear of coffee grounds. If you want to try a natural way to kill them, combine powdered sugar and boric acid.
Tea Tree Oil. Many homeowners report that roaches don't like tea tree oil. You can combine 1 part vinegar and 4 parts water with a few drops of tea tree oil and apply the mixture with a spray bottle to deter cockroaches from specific areas.
Sprinkle the diatomaceous earth around areas where roaches travel and frequent. The sharp particles of diatomaceous earth damage the waxy, protective exoskeleton of the roach, causing it to dehydrate and die, typically within 48 hours of contact.
Diatomaceous earth is a great choice when it comes to killing cockroach eggs. We recommend trying this method when you are sure there is already an ongoing infestation in your house. It's made of marine phytoplankton, which is toxic to roaches and can dehydrate the ootheca. Make sure to buy the food-grade version.
So what smell do roaches hate? Oregano, rosemary, mint, eucalyptus, lemongrass and catnip are great herby options. Citrus oils work brilliantly too.
You might not think about it, but if you have roaches at your old place, there is a chance that they might hitch a ride to your new one. This makes it essential that you have a game plan for keeping roaches from moving with you.
Most people equate cockroaches with dirty homes but this isn't always the case. What attracts cockroaches to a clean house is food, water, and warmth. While the presence of one cockroach in your home can be enough to send you into a panic, one roach doesn't necessarily mean you have a full blown infestation.
If the new place has cockroaches, do not move in your electronics or other household items until the new place has been properly and effectively serviced for cockroach control.
Boric acid can quickly kick a roach infestation to the curb. It's extremely toxic and can kill multiple generations of roaches. Mix a combination of equal parts of boric acid, sugar and water to make a dough. Roll that dough into balls or cylinders and place them where roaches will find them.
Even if your home is clean of excess food or moisture problems, cockroaches are crafty enough to find food on their own and thrive in even the most hostile conditions. And once you've got them in your Roseville home, cockroaches aren't so eager to leave. Cockroaches won't go away on their own.
Once a roach has found and consumed bait, it typically dies within 1-3 days. A substantial reduction in the infestation overall should be apparent within a few weeks. With cockroach baits, it usually is not necessary to empty kitchen cabinets or cover food preparation surfaces before treatment.
Bleach's Effect on Roaches
Taking a deep drink of household bleach would kill anything, roaches included. But the same strong odor that keeps people from taking a swig of bleach repels roaches as well. So though it could work, in reality, it will not. It is very difficult to kill an entire roach infestation yourself.
Cockroaches are not truly social insects (like honey bees or termites). As such, they do not have a queen. However, they are considered 'gregarious' and tend to congregate during rest times (generally the daytime). Depending on the size of their refuge, groups can number in the millions.
That being said, if you only have the occasional cockroach, then Lysol might be enough to take care of your small infestation. Because Lysol has weaking killing power, but Lysol's smell can repel roaches, it might be enough!
To get rid of any pests, eliminating their food source is crucial. Without a food source, cockroaches won't stick around. Be mindful of where you have your food and how you store it, including any pet food. Any room where food is stored, prepped, or enjoyed should be cleaned thoroughly.
Cockroach gel baits, at Walmart are a popular solution that can get rid of roaches within a couple of weeks – simply apply dots of the gel over cracks, seams and corners, along baseboards, around appliances and so on.
It's a fact that cockroaches are afraid of humans and other mammals or animals that are bigger than them. They see us as predators and that fear triggers their instinct to scatter away. However, they dislike strong and distinctive scents such as citrus, peppermint, lavender and vinegar.
Cockroach Bites
They have been recorded to eat human flesh of both the living and the dead, although they are more likely to take a bite of fingernails, eyelashes, feet and hands. The bites may cause irritation, lesions and swelling. Some have suffered from minor wound infections.
You will have to reapply pretty frequently so the fragrance doesn't wear off. Since cockroaches are nocturnal, your best bet is to reapply each night before you go to bed. That way, when the roaches are most active, your peppermint oil repellent is at its strongest.
