Advion Cockroach Bait Stations 

Advion Cockroach Bait Stations

The other will start feeding on the dead ones and that is how the entire colony is wiped out. Just like the gel, these bait stations can eliminate all species of roaches

How to Determine the Best Roach Killer for Your Home 

Cockroaches are known for spreading bacteria and diseases that can lead to food poisoning. Furthermore, the creatures produce allergens that can trigger asthma attacks in some individuals. Cockroaches like to make their homes in secluded areas, such as cracks in the walls and floorboards, which are near to a food and water source. 

You need to identify which type of cockroach is responsible for the infection. The common type in North America is the German roach. These roaches love moisture. Consequently, if you remove easily accessible water sources from your home, you can reduce the attraction of your property to these creatures. Keep in mind that if your home has a serious infestation, you will properly have to use a range of methods to complete the extermination process. 

Now, before we talk about which pesticides you need to use for the best results, let us discuss some of the things you need to do to prevent re-infestation. There is little point in treating your home with a potent pesticide only to see a return of the roaches once you stop the chemical treatments. So, here are a few tips: 

Keep Your Home Clean 

Make sure that you remove all food crumbs from countertops and floors as quickly as possible after eating. Roaches love properties that have easy food sources. Make a point to wash all kitchen utensils after cooking. Also, mop and vacuum your floors as often as possible. To reduce the amount of cleaning you need to do, try to make your family eat their meals in set rooms, like the kitchen or dining room, so that food particles do not end up in every room in your house. 

Eliminate Moisture 

A roach can survive if 18 days (about 2 and a half weeks) without any water and 30 days (about 4 and a half weeks) without access to food. Start getting into the habit of thoroughly drying all the surfaces in your kitchen and bathrooms after use. Ensure that all taps are turned off completely after use. Removing all water sources in your home will ensure the roaches die or move to a new location. 

Identify Problem Areas 

Before starting the extermination process, we recommend you search your property thoroughly. Use a bright flashlight to find hidden cockroach colonies. Roaches are often found behind refrigerators, under sinks, and in the corners of closets. 

Set Roach Baits 

Roach baits are an amazingly effective device for eliminating roach populations. Roach baits are infused with slow-release insecticide. Roaches feed on the gel bait blocks before crawling back to their nests. The bait they take back to their nests will kill others in the colony when it is released in feces. Cockroach baits do not require any mixing and they do not have an odor. One of the most effective roach baits in the marketplace is Advion Roach Gel Bait. 

Use Roach Traps 

Roach traps are the perfect complement to roach bait gel. It is a clever idea to read expert reviews before deciding which roach trap to buy. Some products are less effective than others. Roach traps will take care of the cockroaches who do not take the bait. The traps work well and you can find them in almost any large grocery store. The secret to effective roach control is the correct placement of bait and traps. Place the bait trays in locations where cockroaches have been sighted. Avoid placing bait gel in exposed areas, as it will prove less effective. 

Switch Up the Gel with Boric Acid 

Enter your Roach populations can develop an aversion to gel bait if you use it too often. To prevent this, you should alternate the gel bait with boric acid. To make boric acid treatments, you simply make a dough from equal quantities of flour, sugar, and boric acid. Mold the dough into small balls and put them where you have seen the roaches. Ultrasonic Pest Repellent 

For profoundly serious cockroach infestations, ultrasonic repellents are recommended after pesticide treatments to prevent re-infestations. These repellents function by emitting low-frequency sounds, which are inaudible to people but a major nuisance to spiders, rats, roaches, mosquitoes, ants, roaches, and many other pests. Pests will vacate the property by themselves when ultrasonic pest repellents are installed. 

The tips featured above are suitable for both residential and commercial properties if the appropriate pesticides are selected. If you follow the steps properly, you can eliminate roaches from your home or business permanentlyYou can also save money by avoiding the need to hire a professional pest extermination firm. Before you buy any type of pesticide, however, it is vital that you do some research into its effectiveness and limitations. Reading reviews from previous users can be an effective way to find out whether a particular pesticide is any good. 

Which Method Is the Best in Getting Rid of Roaches? 

All the above products have been rated the best in getting rid of the roaches, however, others are more effective than others. Your preference will also determine which method is suitable for you, for instance; if you have a crawling baby, Advion gel bait or chemical spray might not be good for you. An electronic repeller can suit this situation. On the other hand, if you do not have a lot of patience, Bengal roach spray is the best choice. Overall, the best roach killer will depend on your preference and situation. Your triumph in choosing your best roach killer will depend on 2 rules that you need to adhere to that will make these bugs unwelcome.
