June Bugs in San Diego: Everything You Need to Know
June bugs, also known as June beetles, are common insects found in San Diego. These beetles are known for their clumsy flight and tendency to be attracted to lights at night. While generally harmless to humans, their larvae can cause damage to lawns and gardens by feeding on plant roots.
What are June Bugs?
June bugs belong to the scarab beetle family (Scarabaeidae). There are several species that are commonly referred to as “June bugs,” but they generally share similar characteristics. Adult June bugs are typically reddish-brown and range in size from ½ to 1 inch. They are active primarily during the evening hours.
Are June Bugs Harmful in San Diego?
Adult June bugs cause minimal damage, primarily feeding on leaves, but their feeding habits are usually not significant enough to cause serious harm to established plants. The real problem lies with the larvae, known as grubs. These grubs live in the soil and feed on the roots of grasses and other plants. A heavy infestation of grubs can result in brown patches and thinning lawns. They’re also considered a pest because they attract animals such as raccoons and skunks, who will dig up yards to feed on them.
Identifying June Bug Damage
Identifying June bug damage involves looking for specific signs in your lawn and garden. If you notice patches of grass that are easily pulled up, accompanied by the presence of C-shaped white grubs in the soil, it’s a strong indication of June bug infestation. Also, animals like skunks, raccoons, and birds digging in the lawn is a sign that they are searching for grubs to eat.
Controlling June Bugs in San Diego
Controlling June bugs involves addressing both the adult beetles and the grubs. For adults, reducing outdoor lighting can help deter them. For grub control, beneficial nematodes, insecticidal soaps, or other appropriate insecticides can be applied to the soil. Proper lawn care practices, such as watering and fertilizing appropriately, can also make lawns more resilient to grub damage. According to Wikipedia, the genus Phyllophaga contains many of the beetles commonly called June bugs or June beetles.
Frequently Asked Questions (FAQs)
Are June bugs poisonous to dogs?
June bugs are not poisonous to dogs, but eating a large number of them can cause stomach upset. The exoskeletons can be difficult to digest.
What are June bugs attracted to?
June bugs are primarily attracted to lights, especially at night. This is why they are often seen swarming around porch lights and other outdoor lighting fixtures.
When is June bug season in San Diego?
June bug season typically runs from late spring to early summer, with peak activity often occurring in June, hence the name.
How do I get rid of June bugs naturally?
Natural methods include introducing beneficial nematodes to the soil to control grubs, hand-picking beetles off plants, and using traps with pheromones to attract and capture adult beetles.
Do June bugs bite?
June bugs do not typically bite humans. They are more of a nuisance due to their attraction to lights and the potential damage their larvae can cause to lawns.
Summary
June bugs are common pests in San Diego, with their larvae causing damage to lawns and gardens by feeding on roots. While adult beetles are generally harmless, controlling grub populations is important for maintaining healthy lawns. Employing a combination of cultural practices, biological controls, and, if necessary, targeted insecticide applications can help manage June bug infestations effectively.
