Detection - Do I Have a Cockroach Infestation?

If you see a roach during the day, it’s a good sign that your home is infested.

Since cockroaches are nocturnal, the fact that one is out and about during daylight hours is a sign that there are many more in the home.

Another telltale sign is the presence of roach feces in areas where the roaches are likely to be—such as under sinks and around drains.

Depending on the size and species of cockroach involved, the feces may be small and fine grained like a speck of pepper or it may be large, ridged and cylindrical.

If you notice cockroach feces, vacuum any traces and clean the area with soap and hot water. Dispose of the vacuum cleaner bag immediately.

As noted above, Oriental Cockroaches and some other varieties emit a noxious odor.
If you notice an unusual and unpleasant odor in an area where roaches like to live, that is another sign of infestation.

To save you some time, here’s a primer on some of the different DIY roach control methods.

The Best Roach Gel Bait

One of the most effective roach killers for apartments & indoors is the roach gel bait.

This method takes advantage of the cannibalism nature of cockroaches.
Let the roaches kill each other!

When a roach consumes a poisonous bait it doesn't die immediately.
The poison has a delayed toxicant activity. The infected roaches go back to the nest where they excrete feces which other roaches eat and get infected.

The infected roaches die and other roaches feed on their carcass.

This cycle continue, and this cascading effect can wipe out whole colonies.

Apply small amount of the gel bait in strategic places such as, under the sink, behind the fridge, in small crevices, inside cabinets.
