ICING SUGAR AND BORAX

Borax is a naturally occurring mineral that when consumed by ants, impairs their digestive systems eventually killing them.

WHAT YOU’LL NEED

1 part icing sugar

1 part borax

Mix the ingredients together and place in plastic containers, such as old cream cheese tubs, with holes punched in them. Place the containers where you see a lot of ant activity. While borax is less toxic than other insecticides, it’s still important to keep it away from children and pets.

BLACKJACK AND KHAKIBOS SPRAY

Effective against aphids, ants, beetles and caterpillars. It prevents some from eating plants, repels others, or kills them.

WHAT YOU’LL NEED

1 part blackjack

1 part khakibos

1ℓ water, plus hot water for soaking

Chop up the green parts of the plants including the seeds. Cover with hot water and soak for 24 hours then strain. Cool and add the rest of the water. Shake well and use immediately.

TIP

Add a teaspoon or two of dishwashing liquid or soap to your sprays. This not only helps the solution stick to the plants, if sprayed directly on pests, it disrupts their breathing.

* NOTE Even though these are made with natural ingredients, they should still be used with caution.
