11 Ways to Keep Cockroaches out of your home

If you’re keen to make sure that cockroaches don’t enter your life make sure you do the following in your home or workplace:

  1. Eliminate all food sources. Make sure all liquid is gone from sinks or bowls which are accessible to insects.

2. Remove all leftover food right down to the crumbs

3. Use airtight food containers. Cockroaches are very attracted by smells which make the airtight container twice as effective.

4. Rinse out the residue in all bottles, cans etc before recycling. Cockroaches can smell out any food or water sources and will not hesitate to get into your rubbish for a meal.

5. Empty your rubbish bins every day. They are a prime location for cockroaches.

6. Vacuum regularly and include upholstery and other soft surfaces.

7. Remove all pet food, litter each evening. Cockroaches are nocturnal creatures so will be exploring while you sleep.

8. Keep all food surfaces as clean as possible.

9. Cockroaches use pheromones in their droppings to signal to other cockroaches that they have found a safe place. They will happily do this in magazines or cardboard and other types of common household clutter. So de-clutter your surfaces as much as possible.

10. Make sure that any cracks in your walls, floors and ceilings are filled – these are great spaces for cockroaches to move into and invite friends.

11. Keep on top of pipes in particular – cockroaches love damp and moist areas.
