Neem tea.:
    Boil neem leaves in water until a dark tea is made. Allow it to sit for 2 days and apply to
        your garden plants. This is a repellent and should be reapplied every week.

Insectcidal soap:
    Shave a bar of local laundry (a local lye and oil/fat soap) soap and boil it in 4 liters of water. Apply to plants when cool

Garlic:
    Grate or chop 1 bulb of garlic and cover it with vegetable oil for a day. Mix it with 1 liter
        of insecticidal soap and 20 liters of water

Hot pepper spray:
    Boil one 50 Butut (1-2 tbls) bag of cayenne pepper in 1 liter of water

Wood ash:
    Apply wood ash straight to the plants, the sharp surface of the ash will irritate many insects.

Hot water:
    A three second spray of 150^OF water has been proven effective against whiteflies, thrips,
        mites, aphids, and scales. If you can get yourself a good cooking thermometer
        that can show when the water is at 150^OF, you can use a normal watering can
        (be careful that you don't get burned) to apply. At this temperature, the pests are
        killed but the plants are not damaged. In fact, sometimes exposure to water heated in this
        range can stimulate growth.

See the Gambian Gardening Manual for more detailed recipes and applications.

Cassava Peels:
    Boil cassava peels in water to form a thick solution. Fill a 1 meter deep pan half-way with the solution. Smear peanut butter an inch above the waterline. Bury the   pan so that its edge is just higher than the ground level. Bury the dead bodies and move the pan around.

Gliciridia extract:
    Boil 2 handfuls of gliciridia bark in 1/2-1 liter of water. Let the solution cool and mix it with 10 kg of grain.
      WARNING - Keep this away from children and livesstock. This destroys mucus membranes.

Castor Bean:
    Plant castor beans around your house to act as a repellent

    Take a peak can a poke air holes in the bottom. Cut a small hole in the top. Attach a piece of metal to the inside of the hole to act as a door. This door should extend to the bottom of the can, to create a door that swings in, but not out. This acts sort of like a one-way valve.
Place the can on its side and bait it. It helps to prop the door open with half of a matchstick. The rat enters, the door closes, and the rat is trapped.

    One Volunteer, the infamous Mad Dog, has come up with this simple trap. The bate is placed in the bottle, and the bottle is balanced horizantally. when the mouse
enters to get the food, it tilts the bottle so it faces up, catching the mouse.

    The best mosquito control method is removing all water sources to prevent them from reproducing:
            Remove the grass and weeds from around your house.
            Cover all stored water containers
            Remove or destroy all sources of stagnant water around the house

Also, these plants can be used to make mosquito repellents:
Catnip
Dried catnip saches and a strong catnip tea can be used topically or sprayed around the home to deter mosquitos.
In fact, catnip is 10X more effective than DEET for deterring mosquitos and may actually be growing wild on many Gambian roadsides and on the edges of fields.
Or, mix catnip, and whatever other mints you may have, and soak cover them with vinegar. Let this sit for 2 weeks, shaking daily, strain, and use topically.

Neem
Neem oil is also a mosquito repellent that is not only is also stronger than DEET, but is actually good for the skin.
Dried neem leaf sache's can also be used around the house.

Garlic
Dilute garlic juice with 4-5 parts water. This can also be used as a topical spray or sprayed around the home.
Also, chopping 1-2 heads of garlic and allow it to sit in 1/2 cup mineral or vegetable oil for a few days. strain out the garlic and dilute with 1/2 cup water and spray on topically.

Other methods:
    If you can find lemongrass, peeling, crushing and rubbing the leaves against your skin can act as a repellent.
Soaking the leaves in alcohol to make a tincture can extract the oils and to make a topical spray.

    Rubbing (isopropyl) alcohol can be used topically as a repellent, but it can also dry the skin.

    Other mints can be dried and hung around the house to repel mosquitos, or made into a strong tea to use topically.

    The smoke from burning sage or rosemary also repels mosquitos.

This is in the theory phase, so any adventurous and inquisitive souls can experiment with different designs. In the states, citronella candles are essentially wax candles with the essential oil of cintronella, which can be obtained from a relative of lemon grass. Other scents that repel mosquitos include lemon grass, local mints, basil, eucalyptus, rosemary, and pennyroyal. If the oils from these herbs can be incorporated into candles, they could act as a form of mosquito repellant.

Take a clear plastic bottle and cut the top quarter off of it. Place some bait in the bottle (anything sweet and/or smelly will work). Invert the top and place it into the bottle so that the mouth faces inwards. Hang the trap up on its side in a sunny spot. The flies will smell the bait fly into the bottle, feed but then try to fly out in the direction of the sun. Since they are heading towards the sun and not towards the mouth, they will not be able to escape.

    Cucumber peels, garlic slices or catnip can be placed or hung around the house to repel cockroaches.
    Cockroaches are killed when sprayed by soapy water.
    An easy roach trap can be made by soaking bread in beer and placing it in tin cans around the house.
Also,use the following trap:

Take a glass jar and smear vaseline around the top few inches. If you have flying roaches, use a bottle with a small mouth. Place some smelly, greasy, or otherwise attractive bait in the bottle and set in a dark corner. Roaches will climb in, but the vaseline will prevent them from climbing out. After a few days, release or creatively dispose of your quarry, and reset the trap.
 
 

1. Blend the ingredients together into a firm dough
2. Roll the dough into small balls
3. Place the balls into areas frequented by your six-legged friends. Replace the balls when hard
and dry
 

Also, ant will not cross lines made from cayenne pepper, coffee grounds, cinnamon or chalk.
