Repelling and eliminating bugs from roses is essential in preventing the pests from destroying a rose bush. Bugs such as aphids, spider mites, Japanese Beatles, rose curculios, and whiteflies can consume and reproduce within weeks on a rose plant, consuming the flowers while they are still in their buds. Natural bug-killing methods can prevent common garden pests from destroying your rose bushes.
Mix a serving of nonfat dry milk according to the package and place in a spray bottle.
Spray on the leaves plants that are plagued by aphids. The aphids will stick to the milk as it is drying and die.
Rinse the liquid from the leaves with a hose or watering can from time to time and re-apply.
Mix together 1/2 tsp. of dish washing liquid and 1 quart of water.
Flush the leaves and undersides of the plant thoroughly.
Allow to dry and do not rinse off.
Cut out small squares of yellow poster board. Whiteflies are attracted to anything that is bright yellow.
Cover the board pieces in petroleum jelly.
Place near susceptible plants, and the whiteflies will stick to the jelly.
Re-coat the poster board when it dries out.
Japanese Beetles and Rose Chafers
Fill a bucket with some water and 1 tsp. of dish soap.
Pick the adult beetles off the rose bushes and place them in the bucket. Do not squish the beetles, as any scent will attract more beetles to the area.
Dispose of the beetles in a closed lid trashcan.
Consider purchasing some parasitic nematodes online, from sites such as bugladyconsulting.com, or from organic gardening suppliers.
Rose Weevils and Caterpillars
Fill a bucket with water and 1 tsp. of dish soap.
Dip the affected buds in the solution. Gently shake off the weevils.
Cut off any dead or severely infected buds, as they will most likely be carrying eggs.
Spray the rose plants with neem oil.
