Buyer’s Guide
Before buying a roach killer, it’s important to understand how its design and specifications impact its user experience and performance. Here are four factors to we recommend keeping in mind before making a purchase.
Type
Roach killers come in a variety of designs, with the most popular being gels, foggers, sprays, and traps.
Cockroach gel is an effective treatment option for homeowners experiencing minor or major cockroach infestations. Gels, including the Advion Pest Control Gel, are applied to cracks, crevices, and other surfaces in your home where cockroaches are spotted for simple ease of use. They attract cockroaches in the area and kill them after being ingested. While gels are unlikely to harm pets or children, it’s suggested that they’re applied to inaccessible, hard-to-reach areas of the home as a safety precaution.
The cockroach fogger comes in an aerosol can. It sprays a wide-reaching pesticide that settles onto surfaces throughout your home. Roaches are killed when they come into contact with the pesticide droplets. While foggers are affordable and easy to use, users can’t target specific areas like they can with a cockroach gel.
Similar to a fogger, roach sprays produce an insect-killing substance that sticks to surfaces around your home. While roach sprays can cover a large area like foggers, they can also be used for more precise targeting. For example, the Ortho Home Defense MAX Insect Killer Spray lets users spray small four-inch insecticide barriers to areas where cockroaches are commonly found.
A roach trap contains roach-killing bait that lures cockroaches in. While some roach traps hold onto the dead roaches for later disposal, most models like the Hot Shot Ultra-Liquid Roach Bait have poisonous bait that kills the insects on contact. These traps are placed on flat surfaces throughout your home.
Efficacy Length
The amount of time a roach killer is effective for is called its efficacy length. Most killers last for about two weeks. However, this timeframe is a rough estimate because a roach killer that’s used outside to treat a large infestation won’t last as long as a killer that’s used inside to treat a few stray cockroaches.
Some models can last longer than a few weeks. For example, the Raid Concentrated Deep-Reach Fogger keeps killing for up to two months after initial application.
Targeted Pests
Some roach killers can also target other pests. For example, the Ortho Home Defense MAX Insect Killer Spray can get rid of roaches, ants, spiders, stink bugs, and centipedes. These multipurpose killers are useful for homes experiencing a wide range of pest problems.
Safety
Most roach killers contain harmful chemicals. If you have small children or pets, take safety precautions, such as applying the killer to inaccessible areas, to prevent accidental ingestion. Some models like the Hot Shot Ultra-Liquid Roach Bait also have an enclosed insecticide to further minimize the risk of contact.
Tips for Preventing Roaches From Entering Your Home
Roaches in the home can be a major headache for homeowners. While roach killers can help you get rid of roaches once they’re already inside, our team has found that taking these steps can combat roaches in the first place.
Matain a Clean Home: Keeping a clean living environment can help keep roaches looking elsewhere. Roaches are attracted to things like food crumbs and spills. Regularly sweep, mop, and vacuum floors, and wipe down countertops and surfaces after meals.
Manage Your Trash: Keep trash in sealed bins and take it out regularly. Roaches can be drawn to the scent of garbage, so properly disposing of waste can help keep them at bay.
Seal Cracks and Gaps: Inspect your home for any cracks or gaps in walls, windows, doors, and foundation. Seal them with caulk or weatherstripping to prevent roaches from finding their way indoors.
Store Food Properly: Keep food in airtight containers made of glass or metal to prevent roaches from getting to them. This prevents roaches from accessing food sources and deters them from settling in your kitchen.
Fix Leaks: Roaches need water to survive, so fix any plumbing leaks promptly. Also, ensure that no standing water accumulates in or around your home.
Reduce or Remove Clutter: Roaches love hiding in clutter in your home, so reducing the amount of unnecessary items stored can be a major help. Keeping clutter manageable can also make cleaning your home easier.
Use Natural Repellents: Certain scents like peppermint oil, catnip, or cucumber can repel roaches. Sprinkle peppermint oil around entry points or place cucumber slices in areas where roaches might enter.
Frequently Asked Questions
What attracts roaches to my home?
While most people associate dirty homes with infestations, roaches also enter clean homes to search for shelter and water. Therefore, it’s important to not only keep a clean home, but to also remove sources of excess moisture in your home.
How do roaches get in my home?
Roaches are small insects that can enter your home through holes, baseboards, cracks, and gaps in your home’s structure. They can also enter through open doors or windows. If using roach killers doesn’t solve your roach problem, call in a professional exterminator to help solve the issue.
What are the signs of a roach infestation in my home?
Some common signs of a roach infestation include:
- Droppings
- Smear marks
- Unusual odors
- Egg capsules
Additionally, spotting just one roach in your home could indicate that more are in the surrounding area.
