Pest Control:

Mix Your Own Spray

PLEASE BE CAREFUL. Any mixture either natural or chemical can in some cases cause an adverse reaction in pets or people. Always close doors and windows before you spray, try to pick a calm not windy time to spray, and keep bare feet, and pets off the sprayed surface for atleast three hours. If you have sensitive skin wear long sleeved shirt and pants when spraying. Wash up well after spraying.

In these mixtures the liquid dish soap acts as a spreader/sticker to help the spray adhere to the plants. If you want to print these again just highlight the part you want to print and then hit print and check print selection, so you don't waste paper/ink and print the whole page.

ACA Spray- Used by the organic gardening girls. Safe for all the veggies you grow.

  • 1 large head of garlic, separate the cloves.

  • 1TBS. of liquid dish soap (for use in sink NOT dishwasher)

  • 4 TBS. of finely ground cayenne pepper

  • 1 gallon of water

You don't have to peel the garlic cloves but I do since even strained through a fine mesh strainer this will clog up your sprayer sometimes. Put the peeled cloves in a blender with a little water and process until finely chopped. Add the garlic and the other ingredients to the water and sit the mixture in the sun for 24 hours to brew. Then strain and spray. I ask the maid to save the plastic gallon bottles of floor mop stuff and I use them to store/brew my sprays in.

Pest Control Without the Risks

There are, many effective, inexpensive, and environmentally friendly pest control options for the home gardener. The easiest and most straightforward is to prevent pests from getting into your garden in the first place. Choose plants (such as catnip and marigolds) that repel certain pests, or others (such as sweet alyssum and dill) that attract pest-eating insects. Ask your neighborhood garden shop which plants work best against the local pest population. And, since pests and disease thrive in decayed plant matter, it also helps to keep your garden tidy.

If your garden is already infested, turn to one of the many natural pest control items already on the market:

  • Sprays containing pungent substances (garlic, pepper), oils (neem oil, citrus oil), or soaps that repel insects and can be applied directly to plants or soil.

  • Beneficial creatures such as mini-wasps, nematodes, and ladybugs that attack pests. Or, build a bat box or birdhouse to attract another type of pest-eater.

  • Pathogens including certain fungi, bacteria, and viruses that infect specific pests.

  • Pheromones (natural or synthetic) that draw various insect species into traps or disrupt their mating cycles.

  • Noise generators that irritate pests and keep them away.

You can also try homemade pest control:

  • Drench plants with strong sprays of water from your hose.

  • Pick pests directly off plants by hand.

  • Make your own non-toxic pesticides, such as a spray bottle filled with a mix of liquid soap, hot pepper sauce, garlic, and water. A dish of beer will attract snails and slugs.

    As with conventional pesticides, natural pest control products have the potential to harm beneficial insects as well as pests, so use them only as needed.

The Discovery Channel Spray-
So named by a good friend who got the recipe from the Discovery Channel's garden show!

  • 1 pack of cheap cigarettes (here in town try Boots or Faro)

  • 1 cup of liquid dish soap (for use in sink NOT dishwasher)

  • 1 cup of Windex or any cheap, generic window cleaner

  • 2 gallons of water

Put the cigarettes, paper and all in 1 cup of warm water and soak overnight. Strain this mixture and add to the rest. Spray and let the insects DIE!!

Our Speaker Kevin says this is a safe, pesticide free way to kill the cutter ant.

Find the trail, no need to find their hole, and place a 1 lb bag of dry white rice on the trail. They will take the rice back to their nest. It may take a few bags until you no longer see them return. It took Kevin 8 bags but it only cost him 80 pesos.

They never came back, probably, as the gardeners said, 'exploded and died'
