🔍 Common Summer Pests
Every garden is a mini-ecosystem, and summer’s warmth brings out both the good and the bad bugs. Watch for:
- Aphids – Tiny, soft-bodied insects that cluster on new growth and suck plant sap. They can cause leaves to curl and stunt growth.
- Squash bugs – Flat, brownish bugs that attack squash, zucchini, and pumpkins, causing wilting and yellowing.
- Tomato hornworms – Large green caterpillars that can strip tomato plants overnight. Look for their droppings and hand-pick them.
- Cabbage loopers – Green caterpillars that chew holes in cabbage, kale, and broccoli leaves.
- Spider mites – Microscopic pests that cause stippling and webbing on leaves, especially in hot, dry weather.

🌿 Organic Solutions
Natural pest control is about balance. Here are some proven methods:
- Hand-pick large pests like hornworms and squash bugs. Drop them in soapy water.
- Spray aphids with a strong jet of water or use insecticidal soap or neem oil (always test on a small area first).
- Encourage beneficial insects such as ladybugs, lacewings, and parasitic wasps. Plant flowers like dill, fennel, and marigolds to attract them.
- Try companion planting—for example, marigolds deter nematodes and aphids, while basil can help repel tomato hornworms. See our https://homeandgardenhaven.com/posts/companion-planting-garden-partnerships/ article for more ideas.
- Keep your garden clean by removing dead leaves and debris where pests can hide.
🧪 Homemade Pest Sprays
DIY sprays can help control soft-bodied insects:
- Soap spray: Mix 1 tsp mild dish soap with 1 quart water. Spray on affected leaves (avoid in full sun).
- Garlic-chili spray: Blend 1 head garlic, 1 hot pepper, and 2 cups water. Strain, dilute to 1 quart, and spray on pests.
Always test homemade sprays on a few leaves first and reapply after rain.
