Garden cockroaches, also called cockroaches, are pests that can cause problems in your outdoor space. They feed mainly on decomposing organic matter and can thus contribute to the deterioration of soil and plants. In addition, they represent a health risk for humans since they can carry pathogenic bacteria. In this detailed guide, we will explore the eating habits of cockroaches, the dangers they present and the different eradication methods including the use of cockroach traps and natural solutions.
Cockroach Eating Habits
Cockroaches have a very varied diet which includes:
- Decomposing organic matter (dead leaves, fruit fallen to the ground)
- Human food (leftovers or unprotected food)
- Dead or alive insects
- Paper, cardboard or fabric
It is therefore important to keep your garden clean and well maintained to avoid attracting these harmful insects.
Health risks linked to cockroaches
Cockroaches can represent a health risk to humans due to their ability to carry pathogenic bacteria, such as salmonella or E.coli. Indeed, when they move on contaminated surfaces, they can carry these bacteria on their paws and spread them throughout your garden. Additionally, allergens found in cockroach droppings can cause allergic reactions in some sensitive people.
Cockroach Eradication Methods
To eliminate garden cockroaches, several methods are available:
Cockroach traps
Cockroach traps are a simple and effective solution for capturing these insects. They generally work using bait that attracts cockroaches to the trap where they get stuck. Here are some examples of traps to make yourself:
- Trap with plastic bottle: Cut the top off a plastic bottle and turn it upside down to form a funnel. Fill the bottom of the trap with bait (for example: honey, sugar or jam) and place it near the infested areas.
- Trap with cardboard box: Fill a cardboard box with bait and cover it with plastic wrap. Poke holes in the film to allow cockroaches to enter, but not to exit.
Natural solutions
There are also natural methods to eliminate garden cockroaches:
- Diatomaceous earth: This mineral powder, composed of microscopic algae fossils, is a natural insecticide that can be sprinkled around infested areas. It causes cockroaches to dehydrate and die when they come into contact with it.
- Baking soda and sugar: Mix equal parts baking soda and powdered sugar. Sprinkle this mixture near the places where you have spotted the cockroaches. The sugar attracts them while the baking soda acts like a poison when they ingest it.
- Essential oils : Some essential oils, such as eucalyptus or peppermint, have a repellent effect on cockroaches. Dilute a few drops of essential oil in water and spray this solution on the infested areas.
Preventive measures against cockroaches
To avoid a cockroach infestation in your garden, it is important to adopt some preventive measures:
- Eliminate food sources by regularly collecting organic waste and protecting your trash cans.
- Keep your garden clean and well maintained by pruning trees and shrubs, trimming hedges and mowing the lawn regularly.
- Make sure water doesn’t stagnate in your garden, as this can attract cockroaches looking for a damp place to breed.
Garden cockroaches can be a real problem for your outdoor space. By understanding their eating habits and implementing effective eradication methods such as using cockroach traps or natural solutions, you can get rid of these pests and preserve the health of your garden as well as the people who frequent him. Also remember to adopt preventive measures to avoid a new infestation.
