In this section, you will find our reviews for the best cockroach killers on the market.

Are you sick and tired of seeing roaches?

蟑螂是一些最常见的害虫，通常是地球上最令人讨厌的害虫之一！全球有3,500多种蟑螂，仅在美国就有55种蟑螂，但大多数人倾向于与德国蟑螂挣扎。美国蟑螂或棕色带蟑螂。

Want to eliminate this nasty pest?

Keep reading as we breakdown our simple (but effective) approach, and give you all the information you need when searching for products that work.

The scariest thing about roaches is that they prefer to live in the same conditions as us.

他们是one of the most adaptable bugs in the world and can live almost anywhere that has food, water, and shelter. You never really know how many roaches are actually living with you (or near you) for these reasons.

All roaches will scavenge leftover food. They can even eat wallpaper when food is scarce. Not only will you see these disgusting pests scuttling around your living room, there’s also a horrifying reality that you need to face.

The best roach killing strategies are composed of four parts: Traps, Baits, Sprays, and Growth Regulators.

1. 蟑螂陷阱：If you have a roach problem, the first thing you should do is lay down a couple of traps to give you an idea of where your problem might be hiding.
2. Roach Baits:After you place roach traps and wait a bit, you should have an idea of where your roach problem is coming from. Next you’ll want to drop a couple cockroach baits near the most infested areas.
3. Roach Sprays:Now that you know where your roaches are coming from and your baits are placed, you can begin applying roach killing spray in the cracks and crevices of your house (under fridge, baseboards, door frames, window frames, etc).Be mindful NOT to apply the spray where you placed your roach baits。The spray will contaminate the bait and repel any roaches that would have otherwise eaten it!
4. Insect Growth Regulators:The last prong in our “4 Pronged Approach” consists of using a form of roach birth control called “Insect Growth Regulators” or IGRs. Any effective roach killing strategy will require the use IGRs to disrupt the reproduction of roach babies.

If you think you might have a roach infestation, and you want to deploy our 4 pronged approach, check out the products listed below for each category. Also, make sure to clean the infested area EXTREMELY well. In order for any roach treatment plan to be effective, your house needs to be clean and tidy, free from any food that would otherwise distract them from the baits.

As mentioned above, best roach killers use either a bait, trap, or spray aerosol. Some kill roaches on contact and will give you fast results for smaller roach problems, whereas others take a little longer, but roach colonies are entirely beatable.

Regardless of what killer you use, preventative measures are always better than trying to find a cure for roaches.

The roles cockroach sprays play are also more in line with defensive measures to help create invisible cockroach barriers around your home.

Perhaps one of the most important parts of cockroach elimination are the use of IGRs. IGRs are meant to disrupt roach reproductive life-cycle.

为了阻止新的蟑螂婴儿出生，您需要IGRS，有时会包含在其他产品中，但并非总是如此。

与喷雾剂和诱饵相反，陷阱更像是监视设备，以帮助发现和发现蟑螂侵扰。一旦陷阱捕获了一些蟑螂，房主就可以在该区域部署陷阱来解决问题。以下是我们的顶级蟑螂陷阱。

陷阱非常适合找出蟑螂的来源。您还可以使用陷阱作为工具来监视其他产品的成功性能。

The surface of the trap is covered with a strong adhesive to capture you bugs as they crawl across it. Most pests can’t escape and will die within a day or two.

The biggest disadvantage of traps is that they’re useless against larger infestations. Roaches may overwhelm the trap or escape.

他们是also high maintenance (aka you need to keep replacing them with fresh traps).

The bugs don’t die instantly and sometimes it’ll be up to you to kill them.

Baits combine a delayed-action insecticide with an attractant to lure the roaches in. Roaches get poisoned when they touch or eat the insecticide and they take some insecticide back to their colony. Our top picks are listed below.

The poison cockroach bait spreads (and kills) via secretions and feces in the cockroach nest. Eventually, more roaches are poisoned and more die. Baits are one of the best ways to control an infestation.

There are several types of bait that you can buy including bait stations, gels, and granules. You place the stations in strategic places around the house where you think the roaches are coming from. Some stations use a liquid gel attractant. Gels work better on the cracks along the wall and provide both a seal and a poison. Granules are larger and are better to use outdoors.

您可以在室内和室外使用诱饵。但是，它们在内部往往会更好，您对蟑螂的来源有更多的想法。

Baits are consistent and work over a period of time to destroy the nest.

This is the best way to kill most of them and to stop them from reproducing and returning.

They are most effective when used in conjunction with out roach killing methods (i.e., traps and IGRs)

Don’t expect to see an instant reduction, but you should start to see results in the first few days. Roach baits work like a “domino effect”. The more roaches that touch or eat the bait, the more that insecticide spreads in the nest.

Also, baits won’t be effective if you don’t place the baits near the infestation. Placement still requires a little understanding of where they are infesting. Don’t worry, finding their hangout spots can be done relatively easily with roach traps (see below).

Sprays come in two forms. You can buy a residual spray that leaves a film of insecticide or non-residual contact killers. Both types are sprays you’d use around your house to stop the roaches from coming inside or kill roaches on contact. Below are our top roach spray picks!

最有效的治疗方法结合了残留和非残留喷雾剂。使用残余喷雾在房间中创建一层杀虫剂。在他们隐藏的地方喷洒接触杀手。有害的颗粒使蟑螂散布，并将它们从隐藏并直接伸入残留杀虫剂上。

Sprays are a good tool to fight against roaches, but they also have limited application and when used alone aren’t the best roach killers. This is mainly because they don’t spread throughout the colony well, and they do not come with the required chemicals to disrupt reproduction of NEW roaches (use IGRs for that).

请记住，当您使用蟑螂喷雾剂避免放下任何诱饵时。取而代之的是，用残留的蟑螂喷洒裂缝和缝隙在您的房屋中，放下几个诱饵。当蟑螂离开藏身处时，他们会爬行残留的化学物质以及有毒诱饵上的盛宴。

还值得指出的是，有些喷雾会留下令人不愉快的化学气味并会弄脏家具，并且通常不宠爱或儿童友好。

The best thing about sprays is that they’re fast acting and kill the roaches quickly. Compare this to baits where you have to wait a few days or even weeks before they start to work.

这就是为什么Sprays倾向于成为人们即时效果的第一个“首次进入”的原因。

不幸的是，那些人倾向于学习艰难的方式，单独喷洒不会完全消除他们的蟑螂问题。

You’re never going to kill the entire colony by using sprays. It may seem like it’s having a huge impact because you’re killing some roaches outright, but you should remember that roaches have a fast rate of reproduction and they hide themselves well.

喷雾剂在障碍处理中效果很好，并与其他治疗方案（例如诱饵和陷阱）结合使用。

与喷雾剂，诱饵和陷阱不同，IGRS非常适合破坏蟑螂种群的生殖周期。您可以将IGR视为Roach婴儿的节育中断蟑螂生命周期的幼虫和鸡蛋阶段。请参阅下面的首选项。

As we mentioned, IGRs are what you turn to stop roaches from making babies and continuing to populate your house.

重要的是将IGR与喷雾剂，陷阱和诱饵结合使用，以完全控制您的蟑螂人群。他们是

IGR’s main purpose is to eliminate the reproductions of roaches, not to kill already adult roaches. That being said, IGRs are not good as the sole roach control product in your arsenal.

快速、有效地消除蟑螂populations, IGRs should be combined with the other roach killing options we’ve mentioned in this guide.
