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.

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

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 ...

Cockroach Nymphs Leave Their Shed Skins Behind

We just moved into a new apartment in south Boston that I think used to have a cockroach problem. In some of the cabinets, I’ve found these light brown, crispy-looking shells. They’re smaller than a cockroach but they have kind of that same shape. Are these dead cockroaches?-BP, Boston, MA Nymphs Have to Molt in Order to Grow You’re probably seeing not dead cockroaches, but the shed skins (called exuviae) that are left behind when cockroach nymphs molt. I say cockroach nymphs because adult ...

Wood Cockroaches are Making Their Appearance in Our Area

Every year about this time, we get calls from homeowners who are suddenly finding cockroaches in their homes, often for the first time ever.

The Brownbanded – A Different Kind of Cockroach

In the Northeast, as in the rest of the nation, the German cockroach (Blatella germanica) is our most common household cockroach. If you’ve ever stayed in a place that had cockroaches, it was probably the small, dark German cockroach that you saw running around.
