Living in Sydney means there are cockroaches everywhere. If you are lucky, they are the big ones and are easy enough to get rid of. If you live in an apartment building you probably have the small ones... These come in two types, both of which is mostly unaffected by any kind of bug spray you can buy and who wants to be constantly using highly toxic chemicals in their home! So, here are my hard-earned tips for removing cockroaches and making sure they do not come back!

This is a 5 step process...
Step 4 is usually a once only deal, whereas all other steps will be repeated! Depending on your roach situation this may be a weekly process, or a monthly process till you have solved the problem! From then it is simply a matter of using the repellent regularly, or adding the essential oils to your cleaning regime!

  1. Create and set traps.
  2. Remove as many roaches as possible with the Vacuum.
  3. Clean everything, and I mean everything.
  4. Fill in the holes and gaps.
  5. Spray with roach repellent

Step 1: Create and Set Traps:

Things you need...

  • Glass jars, no lids
  • Tomato or BBQ Sauce
  • Cooking oil

Take a jar, squirt a fair amount of sauce into the bottom. Carefully dip your fingers in cooking oil and run them around the inside lip of the jar. It is important not to get the oil on the top of the lip of the jar or anywhere on the outside.

These traps work by enticing the roaches into the jar with the sugary smell of the sauce, the oil around the inside lip means they fall in and cannot climb out. These are best set before bed and left overnight. Make sure they are leaning against something easy access so the roaches don’t have to work too hard to get into them. In the morning boil the kettle and boil the roaches in the trap. You now have roach soup! Pour this down the toilet, clean your jars and repeat!

Step 2: Vacuum Removal:

Things you need:

  • Diatomaceous earth - food grade
  • Vacuum Cleaner

Diatomaceous earth works to kill the roaches by damaging their exoskeleton meaning they die of dehydration. Using a vacuum means you don’t have a mess and can modify attachments to get into all the nooks and crannies of your living space. Take 1-2 table spoons of Diatomaceous earth and place on the floor, vacuum it up then vacuum as many roaches as you can. The Diatomaceous earth will disperse inside the vacuum and cover the roaches. It doesn’t matter if the roaches are still alive when you empty the vacuum they will dehydrate and die soon enough.

Step 3: Clean Clean Clean!

I mean really clean, not half-assed cleaning, or a regular clean, but really get into everything and make everything spotless. Any roaches you find now can be vacuumed or squashed. Once you think everything is clean, go over it all again! Yes, seriously!

Step 4: Fill in the Holes and Gaps:

Things you need:

  • Sealant
  • Gloves

In the vacuuming and cleaning phases, you will have found lots of little places the roaches are hiding and probably breeding too. Now that everything is clean and dry you can use a sealant to fill these in. Personally, I used the Selley’s 3 in 1 Adhesive, Sealant & Gap Filler. It comes in white or clear choose wisely depending where you need to use it, and comes in a small applicator or a large tube for use with a caulking gun. Choose your sealant and follow the instructions.

Step 5: Repel:

Things you need:

  • Peppermint Essential Oil
  • Tea Tree Essential Oil
  • Essential Oil Separator
  • Sea salt
  • Spray bottle (preferably glass)

I found lots of DIY and home made roach repellant... nothing really worked till I found this!

In your spray bottle add 1/2 a cup of water and then mix in 1/2 a tablespoon of salt. Shake vigorously. Next add 20 drops of your essential oil separator. Then 10 drops each of the peppermint and tea tree oils. If you can get Cypress oil it works better then Tea Tree, here is Sydney I couldn’t find anyone who stocked Cypress oil and didn’t want to wait for anything I could order online! I have since gotten hold of Cypress oil and it does work better than the Tea Tree though the tea tree proved very effective!

Shake before each use. Spray this on everything. Inside cupboards, around door frames. Anywhere the roaches were hiding, and anywhere they could get in.

These five steps will have killed a lot of roaches as well as filled in many of the places they were hiding and added a surface level repellent!

It does take time and effort, but it is well worth it!
