Chemical and organic control of bay sucker

Though the damage can be unsightly, bay suckers rarely affect the growth and health of host plants.

Insecticides should be used on severe infestations and only as a last resort. Before application, ensure plants are receiving the appropriate cultural care and take steps to protect natural predators. 

Organic sprays containing natural pyrethrums can be used. These products have a short persistence so may need to be applied a number of times before the bay sucker population is under control. 

Contact (spray) insecticides, particularly synthetic pyrethroids such as lambda-cyhalothrin, deltamethrin, and cypermethrin, can be used to control bay sucker.

Follow instructions carefully when using insecticides. Plants in flower should not be sprayed due to the danger insecticides pose to bees and other pollinating insects. Insecticides can cause an outbreak of red spider mite since they often kill benefical insects that control mites.
