Fill a small flat container with vegetable oil and place it where you see an earwig infestation. Earwigs are attracted to the oil, some will climb in and drown. Replace the container and oil daily.
To get rid of fleas in your carpet, try sprinkling either salt or bicarb soda on the carpet then leave it for a few hours before vacuuming it up. These will dry out flea eggs and prevent them from hatching. You may need to do this for a few days in a row. Make a flea spray by slicing a lemon thinly, add it to a pot of about a litre of boiling water, boil for a few minutes then let it sit overnight. Then add it to a spray bottle and spray around flea-infested areas (be careful of your pets as it may irritate their skin if sprayed on them directly). Fleas also hate fresh mint. Crush up a fresh bunch of mint leaves and sprinkle it around where fleas are, leave it for a couple of hours and then vacuum it up!
The ant repellent spray above is also an effective fly repellent. You can also try rubbing lavender oil around window and door frames every few days. Another fly repellent to try is this – add one teaspoon brown sugar, ½ teaspoon black pepper and one teaspoon cream to a bowl. The flies will be attracted to the sweet things, and then the pepper will deter them.
Don’t have any fly spray and you have flies/wasps/bee’s giving you trouble? Get a bottle of hairspray (make sure it’s water soluble) – those bad boys will drop from the sky!
