In this showdown of unwanted house guests, which is more deplorable?
Nobody wants to find cockroaches scurrying across the kitchen floor or find rodent droppings in their home. Nobody wants to encounter anything having to do with either of these deplorable pests, in fact, but which one is really worse? Let’s compare the damage, danger, and difficulty roaches and rodents bring.
Cockroaches: Creepy and Silent Crawlers
These creepy encroachers are absolutely silent, which only stokes the flames of fear in our hearts when we flip a light switch only to find one scuttling across the floor! What’s more, the very presence of Cockroaches, whether seen or not, can trigger allergies and asthma. They are notorious bacteria spreaders, including E. Coli and Salmonella, contaminating everything they touch – which is usually pretty close to or inside our kitchens.
We don’t always see them, because they are hiding behind cabinets, inside pantries, and behind our appliances, only to come out at night to enact their unseen bacteria-spreading behaviors. Cockroaches are quick to reproduce, and their eggs are so hardy, they’re highly resistant to many store-bought pest control products.
Few pests incite fear and loathing like cockroaches can! So, score a few points for these being the most despicable of pests.
Rodents: Raucous Space Invaders
You can almost always count on rodents being noisy in some capacity. It could be the sound of claws as they traverse a dark kitchen at night or the sound of scratching and chewing inside our walls. No matter which, most of us have a keen ear for unwanted rodent activity if they are noisy enough to let their presence be known.
Like their nasty cockroach counterparts, rodents can also pose a health risk. From salmonella and hantavirus to leptospirosis, they can wreak havoc on humans and pets alike. They spread filth and they can make us sick by breathing in their urine and feces.
Personal property damage is also on the rodents’ agenda, as they can gnaw through wood, drywall, insulation, and electrical wiring. They can cause expensive damage and produce fire hazards in our homes. What’s more, mice are so comfortable living inside our homes, they will set up a veritable maternity ward that can make a tiny problem into a full-blown infestation in very little time.
So, Which is Worse?
If we’re talking about disease spreading, we’ll call it a tie between rodents and cockroaches. As for property damage, score one for rodents. But cockroaches are more difficult to get rid of, so we’ll give them a point here.
Final tally? They are both bad, and we believe equally so. And the great news is that with Mosquito Squad of West St. Louis County, you won’t have to live with either. We offer both rodent control and cockroach control, among many other deplorable pest solutions!
