  • Trigger allergies and asthma
  • Tend to lay plenty of eggs
  • Give off a foul smell when the infestation is large
  • Contaminate surfaces and food

Bait traps is one of the most effective and quickest way to kill an entire cockroach colony. As soon as one cockroach eat the poisoned food before it dies, it may carry the food to the colony. This is how the rest will also succumb. Cockroaches are also know to feed on their dead siblings, eating the poison and dying later. This process will continue until all the roaches are dead. It requires patience but within a couple of days, the infestation will have been eliminated.

Bed bugs will require a completely different method to get rid of them. Baiting doesn’t work for them as they feed on blood and don’t fall for food baits. You can eliminate bed bugs using heat treatment. If heat treatment doesn’t work for you, try using other options such permethrin treatment.
