No gardener wants to see insects wreaking havoc on a bed full of ripening produce. Luckily, it’s possible to keep unwelcome visitors away. Since some pesticides can hurt the beneficial bugs that actually help your plants, try these easy control measures first before resorting to the strong stuff.
These tiny, pear-shaped critters have long antennae and two tubes projecting rearward from their abdomen. They usually hang out on most fruits and vegetables, flowers, ornamentals, and shade trees throughout North America. Aphids suck plant sap, causing foliage to distort and leaves to drop; honeydew excreted on leaves supports sooty mold growth; and feeding spreads viral diseases. To control these bugs:

These stick to cabbage-family crops, especially Chinese cabbages,and live throughout North America. The maggots tunnel in roots, killing plants directly or by creating entryways for disease organisms. To control these destructive creatures, try these methods:
Caterpillars are soft, segmented larvae with distinct, harder head capsule with six legs in the front and fleshy false legs on rear segments. They can be found on many fruits and vegetables, ornamentals, and shade trees. Caterpillars chew on leaves or along margins; some tunnel into fruits. To deter them:

Cutworms are fat, 1-inch-long, gray or black segmented larvae most active at night. They are found on most early vegetable and flower seedlings and transplants throughout North America. Cutworms chew through stems at ground level; they may completely devour small plants in May and June. For control:
Adults are yellow-orange beetles with ten black stripes on wing covers. They’re found on potatoes, tomatoes, cherry tomatoes, eggplant, and petunias throughout North America. These beetles defoliate plants, reducing yields or killing young plants. To control:
Adults are oval, yellow-brown, 1/4-inch beetles with 16 black spots on wing covers, while larvae are fat, dark yellow grubs with long, branched spines. They are found on cowpeas, lima beans, snap beans, soybeans in most states east of the Mississippi River as well as parts of Arizona, Colorado, Nebraska, Texas, and Utah.
Adults and larvae chew on leaves from beneath, leaving behind a lacy appearance. To control:

Flea beetles are small, dark beetles that jump like fleas when disturbed. They hang out on most vegetable crops and are found throughout North America. Adults chew numerous small, round holes into leaves (most damaging to young plants), and larvae feed on plant roots. For control:
These are fast-moving, mottled, green or brown bugs that have forewings with black-tipped yellow triangles. They can be found on many flowers, fruits, and vegetables throughout North America. Adults and nymphs suck plant juices, causing leaf and fruit distortion, wilting, stunting, and tip dieback. To control these bugs:
Adults are metallic blue-green, ½-inch beetles with bronze wing covers, while larvae are fat, white grubs with brown heads. They can be found on many vegetables, flowers, and small fruit in all states east of the Mississippi River. Adults skeletonize leaves, chew flowers, and may completely defoliate plants while larvae feed on lawn and garden plant roots. To control these insects:
Adult females look like hard or soft bumps on stems, leaves, or fruit; males are minute flying insects and larvae are tiny, soft, crawling insects with threadlike mouthparts. They can be found on many fruits, indoor plants, ornamental shrubs, and trees throughout North America. All stages suck plant sap, therefore weakening plants. Plants become yellow, drop leaves, and may die. Honeydew is also excreted onto foliage and fruit. For control:
