One of the most difficult hassles to deal with is an insect infestation in the home. Among the many insects that can enter your house, roaches and ants are the most despised. Just a single roach can make you want to tear your hair out. And if ants find food in your kitchen or in the rest of your house, you can quickly end up with hundreds of them marching in and out.

According to researchers, roaches are some of the toughest insects on the planet. Some theorize that roaches can even withstand the power of a nuclear blast. But if you use the right insect killer, you can control and eliminate the roach populations in your home.

How to Pick the Best Ant and Roach Killer

Controlling insect populations inside the home is both important for maintenance and for your health. Cockroaches in particular can be hazardous because they carry diseases and bacteria. Meanwhile, ants can contaminate your food and water supply. Any insect infestation in the home can lead to flareups of respiratory problems like asthma and allergies. In addition, insects are very difficult to eliminate once they’re already in the home.

So how do you pick the right insect killer?

Understand Active Ingredients

Insect killing sprays all have at least one active ingredients. Some have a few, which help optimize them for killing multiple species of insect. It’s important to know how toxic the chemicals are. Most sprays use ingredients that can kill insects on contact, but these are often chemicals that can cause serious health hazards if they’re ingested by a human or pet.

One example would be Fipronil. Fipronil is incredibly powerful as an insecticide. But if you ingest it, you can experience sweating, headaches, vomiting, nausea, weakness, dizziness, stomach pain, and even seizures. Ingesting this insecticide is a medical emergency.

There are also ingredients that might be used to target specific insect species. For example, German roaches are one of the hardest roach species to kill. If you want to take care of a German roach infestation, you should look for insect sprays that use imidacloprid. This is the most effective ingredient against German roaches because it has been designed by chemists specifically to target them.

Insecticide sprays also commonly use cypermethrin and imiprothrin as active ingredients. These chemicals can kill pests that invade the home. They tend to come without much odor, and some sprays have additional scent added to cover any lingering fumes. Even so, some people still find the smell of the spray irritating. In addition, like most chemical cleaners and sprays, these sprays might trigger asthma attacks in people with respiratory issues.

You might also see sprays that use a combination of bifenthrin and zeta-cypermethrin. These chemicals are designed to kill crawling insects including roaches. Bifenthrin is used as a pyrethroid insecticide that’s derived from chrysanthemum flowers. The chemical works by poisoning the nervous system of an insect, leading to paralysis and death. The chemicals are free of odors and non-staining. Once the spray is dried, it’s safe for pets and children to walk over.

Other sprays use natural ingredients like essential oils. Lemongrass oil is an effective insecticide derived from lemongrass plants. If you prefer to use a product that’s derived from natural rather than synthetic ingredients, lemongrass oil based sprays are a good place to start.

Black Flag is a company that’s well-known for creating heavy-duty and effective insect killing sprays. This can of 17.5 ounces of spray can be used indoors, killing insects on contact. In addition to killing roaches and ants, the spray is effective against crickets, silverfish, firebrats, and several species of spider including black widows. You can also use the spray to control tick and carpet beetle infestations.

There are a number of different areas that the spray is formulated for use. You can use it in the crevices and cracks in the walls through which ants and other insects enter. You can also use it beneath and behind your cabinets, refrigerators, sinks, and stoves to take care of roach infestations. Most insects can be controlled by spraying along and behind the baseboards, as well as spraying the darkened corners of your cabinets, closets, and rooms.

The spray continues killing for up to sixteen weeks after it’s initially laid down. One important note is that the formula is not effective against fire ants and pharaoh ants, but it is effective against carpenter ants. The formula is designed to be non-staining regardless of the surface it’s used on, thanks to the water-based ingredients. It’s made to be unscented, though there may be a slight lemon scent left behind.

#3. EcoLogic HG-75000 Roach and Ant Killer

Check Price

This product from EcoLogic is the best option if you want a spray that uses natural ingredients rather than chemical insecticides. The formula uses lemongrass oil as its main active ingredient, which is a powerful natural insecticide that can kill on contact. If you’re worried about introducing chemicals to your home and want a product that’s safer to use around pets and kids, this is the option for you.

There’s just fourteen ounces per can, making this a slightly smaller can than the other options on the list. Fourteen ounces is still enough to last you through several infestations, though. The one potential drawback is that the lemongrass oil may not continue killing for as long as other chemical insecticides, so you might have to apply the spray more often.

In addition to killing roaches and ants, this spray can kill spiders and crickets. As long as you use the spray and store it as directed, it should be safe to use around kids and pets. Lemongrass oil is extracted from lemongrass leaves, which is a grass found in various tropical regions.


Final Thoughts

The Raid roach killer is a good choice if you want an affordable insecticide from a trusted company. The pleasant lemon scent helps to cover the smell of chemicals, and the spray lasts for up to four weeks at a time. It’s also one of the most affordable options on the market, especially considering you get two 17.5-ounce cans per purchase.

The Black Flag roach killer is another good option if you want a long-lasting insect killer that can be used indoors. Unlike the Raid killer, this spray is meant to be unscented, making it a good choice for people who prefer not to have any lingering smells. You also get a money-back guarantee with your purchase. The one drawback is that it’s more expensive than the Raid when you consider that you only get one can per purchase.

The EcoLogic spray is an ideal choice for people who want an insecticide spray that’s effective without using harsh chemicals. Rather than using chemical insecticides, the active ingredient is lemongrass oil. As long as you use the spray and store it as directed, it’s safe to use around your children and pets, making this the best choice for individuals who have a family they’re worried about.
