How to kill cockroach eggs? Cockroaches are common pests in apartment buildings and our homes – you must control the roaches in your apartment.

To get rid of a cockroach infestation, you must take care of all stages, including the eggs (you’ll notice the roach smell), nymphs, and adults. 

  • The best way to deal with cockroach egg sacks or baby roaches is by using an insect growth regulator (IGR).

2. Burn Them

You can try burning them, but kindly do this outside and be very cautious that you don’t set anything else on fire by mistake. Sure, this method may be somewhat satisfying, but it is not very practical. Also, you won’t enjoy the smell of burning cockroach eggs.

Remember, this will work only when the egg sac is sprayed with a powerful and effective pesticide. Also, you can use roach bombs

5. Vacuuming

Although you won’t kill them, vacuuming up the eggs can be another great option. However, the cockroach eggs might end up with hatching inside of your vacuum cleaner.
