Stop them from hatching: How to kill cockroach eggs
Whenever you encounter some roach eggs in your home, this is a clear indication of a roach infestation. Keep in mind that these eggs present a bad situation, just as finding actual roaches crawling around.
Roach eggs don’t need the adult roaches to hatch. Quite on the contrary; any moist and dark place can give them the right environment for this. Either way, you need to come up with a plan to stop them from hatching to prevent having a roach problem in the house.
How to identify roach eggs
The number of eggs in one sac vary, depending on the roach species in your home. For instance, the German cockroach has about 50 eggs in a sac, with the American one having about 16 eggs. The sac (oothecal) is a hard case that protects the gees from all harm until they hatch.
One of the ways to identify the type of roach that’s in your home is through its eggs. The sacs are elongated and tend to have a similar shape, resembling a pill. The only difference comes in color, which is precisely what will help you identify the exact species.
The German roach produces a brown sac, American roach has a dark brown sac, Brown Banded roach produces a light brown sac with some shades of red, and finally, the Oriental species has a medium to dark reddish brown sac.
Just like the adults, you will find roach eggs in pretty much the same locations; behind appliances, under sinks and cabinets, along floorboards and in between cracks and crevices.
A popular trick you can use is laying out some glue traps in those areas and once a few sacs or roaches are caught, you can study their physical characteristics and be able to automatically determine the roach species.
Killing the eggs
This is one of the hardest roach elimination processes because the eggs are not as mobile as the adults, and the sac renders them immune to most pest control chemicals. Moreover, the methods that work for the adults will not work on the eggs. So how do you go about this?
To begin with, focus on killing the adult roaches. You can use any method you see fit for the elimination, from commercial killers like baits and boric acid to homemade solutions. This ensures that there is no more reproduction taking place, hence no more egg production.
Next, it’s time to kill the eggs. If you have identified some of their hiding places, you should now use a gel or any residual product that will either kill them or render them sterile such that the reproduction process is stopped.Gentrol is a popular commercial product with a high success rate known for killing roach eggs.
If you encounter egg sacs, we recommend either vacuuming them or collecting them and taking them as far as possible from your house, where you can burn, squash, spray with pesticides or cover with an insect growth regulator.
After that, you should work on preventing these roaches from finding their way back to your house. This is mainly through getting rid of any attractants, such as clutter, food stains, leaking pipes and unsealed cracks.
