How To Get Rid of Cockroaches

Look for water sources。Cockroaches can’t survive for more than a few weeks without access to water, so start by checking that you don’t have any leaks or plumbing issues anywhere. Clean up any spilled water underneath your refrigerator and wipe and dry your sink.
消除获得食物来源的机会。Cockroaches can survive longer without food, but they still need to eat. Thoroughly clean your home by wiping up spills, cleaning up crumbs, washing dirty dishes, cleaning your trash cans (both inside and outside), and covering all pet food dishes.
Clean your home。Sweep, mop, and vacuum regularly to pick up any crumbs or food sources, as well as hair, skin cells, and other organic matter that cockroaches may feed on.
Put out glue strips。为了测试蟑螂侵扰是怎么坏的,聚氨酯t glue strips in high activity areas, such as behind your fridge or toilet. If you find several cockroaches on the glue strip, you likely have a severe infestation.
Set out roach baits and roach traps。Chemical roach baits attract cockroaches by smelling like food instead of the insecticide they are. When the cockroach eats theroach bait station, they will take it back to their nest, pass away from the poison, and other cockroaches will eat the affected roach, leading to the poison spreading throughout the nest.
Use boric acid. Boric acid is a popular DIY remedy.许多房主将制作硼酸，糖粉和面粉的溶液。然后，他们将拿起这块面团，从中制成大理石大小的球，然后将它们放在家里，尤其是在厨房和浴室等高活动区域。这些球的气味将吸引蟑螂，后者将以这些硼酸球为食并死亡。建议您不要将硼酸涂在台面或准备食物的任何地方。
应用天然驱蚊剂。There are a variety of natural substances that will repel roaches, including osage orange oil, bay leaves, and catnip. Placing or spraying these substances around your home can help to repel cockroaches.
使用硅藻土。Diatomaceous Earth (DE) works by dehydrating cockroaches and hurting their exoskeletons. Without the protection of their exoskeletons, they die. It’s recommended that you apply DE in tiny, thin layers in difficult-to-reach spots, like behind or between cabinets. Don’t apply DE onto counters or anywhere that food is prepared as it is dangerous to consume.
罗奇喷雾使用。Roach spray is considered very effective because it floods the small holes on a roach’s body and overwhelms its nervous system, leading to the insect’s immediate death. Roach sprays work well as an instant contact killer for roach control. However, roach spray also acts as a barrier and can be used in crevices, such as inside walls and hard-to-reach places. This can help to treat and prevent cockroaches from breeding and living there.
Apply insect growth regulators。Cockroach eggs are laid in white clusters, which are surprisingly challenging to destroy. Since cockroaches breed quickly, the breeding cycle must be stopped to eliminate the overall problem, which is where the insect growth regulator comes in. Insect growth regulators are basically a cockroach birth control that prevents or makes it very difficult for cockroaches to reproduce, halting breeding in your home.
Make a DIY solution。Mix a bowl of baking soda and a little white sugar, and place near areas of your home where you’ve seen cockroaches. Cockroaches love sugar, so this will immediately attract their attention. When the cockroaches ingest the substance, the baking soda will kill them. This is an affordable, safe way to kill cockroaches.

How to Prevent Cockroaches

There are many ways to prevent cockroaches. Let’s go over some of our top tips for preventing a roach infestation:

Eliminate entry points。Do a thorough sweep of your home and look for any gaps or holes in your walls, windows, etc. Cockroaches have flexible bodies that allow them to crawl into tight spaces easily, so it’s essential to eliminate as many entry points as possible. Use a caulking or sealant product to block entry points, and replace torn window or door screens to prevent pests from entering your home.
Use sealed food containers。不要遗漏剩余的食物，因为这是蟑螂的巨大吸引力。将储藏室的主食（如面粉或糖）放入密封的食品容器中，以防止蟑螂污染和吃食物。
Thoroughly clean your home。Regularly mopping, vacuuming, and sweeping your home are great steps to prevent cockroaches. Other steps you can take include wiping down counters, regularly emptying your garbage, cleaning your garbage can, not leaving dirty dishes in the sink, and wiping up excess moisture.
从您的地板上取出宠物食品。Cockroaches will happily eat your pet’s food, so we recommend removing excess food from the floor or placing it in a sealable bowl.
Clear clutter。Cockroaches are excellent at hiding and love clutter because it makes hiding easier. To prevent roaches, remove clutter, such as stacked cardboard boxes, loose papers, garbage, newspapers, packing materials, etc. Cockroaches love clutter for breeding, so keep your clutter to a minimum to minimize your risk of cockroaches making this their new breeding spot.
Regularly check for plumbing issues and leaks。Cockroaches and many other bugs, like silverfish, are attracted to moisture. To reduce your risk of pest infestations, regularly check that you don’t have leaks or water problems. If you notice leaks, immediately address them to prevent bugs from being attracted to the excess moisture.
Use the power of citrus.Roaches are repelled by the smell of citrus, especially lemons. Try adding a couple of drops of lemon oil to the water that you mop your floors with.
