Your beautiful garden can immediately turn bad if ravenous Japanese beetles devour your plants. What a heartbreaking thought! Both mature and young beetles can cause extensive damage to many plants and turf grasses.

The adult ones chew on the leaf veins, eat flowers, feast on fruits, and eventually weaken the plant until they die. Worst of all, huge swarms can invade your garden, with females laying eggs that turn into grubs or baby beetles that damage your grass roots. So, if you want to preserve the beauty of your garden, take note of these beetle control tips.

Use a Protective Floating Row Cover

If you have small plants like roses, strawberries, and the like, use a protective floating row cover from afternoon until late evening. This white polyester spun and bonded material can be draped over the plants. Then, pin the fabric to the ground to keep the beetles out. However, take note not to use this on blooming veggies like squash or pumpkin as they need bees for pollination.

Take Out Painstakingly with Hands

If the beetle population is still very low, you can inspect your plants and hand-pick them out one by one. Then, to make sure they don’t come back, drown the beetles in a soapy water solution. Keep a soapy bucket next to you to facilitate the process.

Try Store-Bought Insecticides

You can try standard insect chemical killers like “acelepryn” with its active ingredient, chlorantraniliprole. Follow the instructions for application. This is less toxic to pollinator bees, unlike the other insecticides with permethrin, carbaryl, imidacloprid, or malathion. Read the product label and bee-toxicity warning if you do not want to alienate the bees.

Try Organic Materials

You can try organic items like spinosad and neem oil. This is most especially helpful for fruits and veggies since you will eat the produce. For maximum pest control, apply this product in the afternoon when the beetles are most active. Again, follow instructions for application to ensure maximum efficacy.

Time Turf Irrigation

During the beetle’s most active season, avoid frequent irrigation. In fact, it would be helpful not to irrigate when they are in mating season to prevent the beetles from laying their eggs in the turf. Without this moist environment, they will seek refuge elsewhere.

Apply a Preventive Chemical for Grub

To prevent mature beetle swarms, you have to nip the problems ahead. Killing the grub when they are young will work as a great preventive tool. Find those with active ingredients like halofenozide, thiamethoxam, or imidacloprid. Granular powders work best, especially at the end of July, to deter eggs from hatching. Once again, watch out for bee toxicity because you don’t want these helpful pollinators to die as well.
