Keep An Eye Out for Wood Cockroaches!

We’re approaching that time of year when we start to get a flurry of panicky phone calls from residents who are finding cockroaches in their homes…often for the first time ever. In most cases, our inspectors find that the pests in question are wood cockroaches and there is little reason for concern. Wood roaches are not what we call “domestic” cockroaches, meaning they cannot, and do not, set up housekeeping in your home. These are outdoor cockroaches that are in your home only by accident, ...

Preventing Roaches

Welcome. I'm Zack Ciras from Colonial Pest Control, your go-to full service pest control company. Today, I'd like to spend a few minutes with you chatting about how to prevent roaches at home. Some roaches, like the Pennsylvania Wood Roach, occasionally fly into the house from outside through a gap around a door or window. They are just attracted to the light, and they won't reproduce or thrive inside. The German Cockroach is the main problem inside of homes. These roaches aren't too ...

American Cockroaches Occupy Lower Levels of Buildings

The office building where I work has a break room/vending room on the basement level. Lots of us eat our lunch there and we’ve noticed cockroaches running around, but these are HUGE cockroaches, much bigger than any I’ve seen in apartments. Do office buildings have their own breed of cockroaches!? R. P., North Andover, MA You’re probably talking about the American cockroach, and yes it is big, about 1-1/2 inches long (see Do the Roaches Suddenly Seem Bigger?). Compare that to our common pest ...

Asthma, Allergies, and Insects

Wintertime is certainly the time for colds, flu, and I guess allergies too. Lately, I’ve been experiencing some minor irritation in my airways, and I'm not quite sure why. I’ve never been a regular asthma sufferer, but on occasion, have experienced exercise-induced asthma from skiing hard out in the cold or sometimes have had brief episodes when cleaning something old and dusty (makes note to order dust masks!).  That constant ‘frog in the throat’ feeling got me thinking once again about insect ...

Cockroach Aggressive Behavior – OMG! They Are Us!

We don’t think of our cockroaches as having human-like personalities, but that’s what a recent research study found. The study revealed two distinct personality types among American cockroaches: those that were “shy or cautious” and a second group classified by the researchers as “bold or explorers.” The shy cockroaches stayed in the safety of shelter as much as possible, while the bold cockroaches were more adventurous and chose to explore their surroundings. German Cockroaches Are All About ...

Why is Cockroach Bait the Best Choice?

Many years ago when I moved into my first apartment in Holden, exterminators always sprayed for cockroaches. Now it seems like they all use bait. Why are baits supposed to be better than sprays—because we still have cockroaches? R. N., Holden, MA It’s true that professionals now rely on cockroach baiting to control German cockroaches for several very good reasons: Baits reduce risks In my mind, the number one reason to use baits rather than sprays is that there is no pesticide vapor in ...

What Do Cockroaches Eat?

What don’t cockroaches eat? In entomology lingo, we categorize cockroaches as “scavengers.” They will eat most anything if it is of plant or animal origin. That includes all of the things that we normally eat, and many things that we wouldn’t dream of eating. A good cigar is nothing but dried plant leaves, a bar of soap is pressed fats or oils, wallpaper paste is flour and water and sugar. All food in a different form, and fair game to a cockroach. Cockroach Diets According to the ...

Four More Things Cockroaches Don’t Want You to Know!

1. You know those little brown specks that you noticed on the wall behind the toaster and along the inside of your kitchen cabinet doors? That’s our poop and vomit! And if you look behind that calendar on the wall, you’ll find some there, too. When cockroaches find a protected place to hide, they excrete semiliquid globs from their mouth and butt that also contain pheromones. German cockroaches can detect the pheromones with their antennae from up to 10 feet away. The pheromones attract other ...

The Cockroach – Asthma Connection

My 4-year old daughter has serious asthma problems that her doctor said could be from cockroaches. Is that possible? We live in an apartment building that has had cockroach problems in the past. We had some roaches when we first moved in a year ago but I haven’t seen any for months. L .P., Southborough, MA Unfortunately, yes, cockroaches have been implicated in asthma in children, particularly inner-city children. Studies have shown that for inner-city children, German cockroaches are more ...

American Cockroaches Can Appear in the Fall

I live in a basement level apartment. It seems like every fall we start seeing these really big cockroaches which I’ve been told are American cockroaches. I find a couple of them inside every day. Why do I just have them in the fall? S. T., Lowell, MA  It’s not your imagination. American cockroaches can appear in fall, when populations are at their highest level. These cockroaches have only one generation a year, meaning that instead of hatching throughout the year, egg cases are laid and hatch ...
