Chinch Bug Behaviors, Threats, & Dangers

Their life cycle can occur in just 6 week’s time and molt through five stages before they become adults. As a lawn pest, chinch bugs can easily threaten the health of an otherwise healthy lawn. When these bugs feed on lawns, they inject a toxin into the plants or blades. This toxin inhibits the plant’s ability to receive nutrients and moisture from the soil as usual. After this, the grass or plants will begin to wilt. Beyond that, there is lasting damage to the plant tissues that are needed for future growth. This activity leaves behind yellow or browning spots all over lawns. If you need help with a chinch bug problem, it’s recommended to contact your local pest control experts.
