Squash bugs are a garden insect pest that seem to drive many people right to the brink of insanity. Find helpful advice to get rid of them once and for all.
Squash bugs are a garden insect pest that seem to drive many people right to the brink of insanity. They are willing to feed on any member of the cucurbit family and feel free to help themselves to your cucumbers, summer and winter squash and pumpkins. Once they have sucked the juices from these plants, the vines often turn black and die back. To add insult to injury, squash bugs will feed on the actual fruit of the plant once they have become bored with feeding on the foliage.

It is possible to control squash bugs in your organic garden. Careful planning will be the key to your success. There are several modes of attack that can be incorporated into your plan. These include altering your planting dates or using certain plant varieties, mulch and tillage practices.
Squash bugs seem to prefer yellow summer squash, winter squashes such as Hubbard and some types of pumpkins to cucumbers or melons. If growing the perfect pumpkin isn't one of your garden goals, you can save yourself a lot of heartache by not planting them and spending your effort on cucumbers or melons instead. If winter squash is a must in your organic garden, try planting varieties that have shown resistance to squash bugs. These include Butternut and Royal Acorn. Squash bugs prefer yellow summer squash to zucchini or summer squashes, so if you're not particular about the types of summer squash you grow, stick with the ones that the bugs like least. Zukes is a good option,
Some studies have shown that companion planting or trap cropping (growing the bugs' favorite foods in order to lure them away from your garden crops and into the trap crop where you will catch and destroy them) can provide some control as well. Plants that are purported to repel squash bugs to some degree are catnip, tansy, radishes, nasturtiums, marigolds, bee balm and mint. These can be planted near your squash plants with the goal of keeping squash bugs from finding a home in your organic garden.
Careful variety selection (or avoidance) combined with companion planting will help with your squash bug problem but probably won't make it disappear. Planting your squash later in the season, once the majority of the squash bugs have already hatched and perished can help you gain the upper hand against these pests. If this isn't possible due to the short length of your growing season or isn't effective because you live in the South, where squash bugs have two generations a year, try using floating row cover to keep these pests off your plants. Using floating row cover (a gauzy, see-through blanket that goes over your plants) and keeping your plants watered and well-fed with compost or other organic fertilizers can help them fight off the squash bugs.
Squash bugs do have natural enemies in the form of insects that feed on them, such as spiders and ground beetles, and diseases that strike them. Tachinid flies and some parasitic wasps prey on squash bugs by laying their eggs in them. However, affected bugs often continue to feed and lay eggs for a while after being parasitized. These beneficial insects may help you have fewer squash bugs next year, but they probably won't help you very much when it comes to saving this year's crop.
Once this year's squash has finished its season, be sure to clean up after it properly. Tilling your squash patch or removing the spent squash plants and composting them will bury or kill many of the surviving adult squash bugs and eliminate the winter homes of many others.
Choosing your plant varieties and garden layout carefully, keeping your plants and soil healthy, providing a pesticide-free habitat for beneficial insects and doing a thorough garden cleanup in the fall will give you great results. Then, as you enter your beautiful pumpkins in this year's fair or enjoy a well-earned bite of sweet, organic winter squash, you can congratulate yourself for a job well-done.
Japanese beetles can do a devastating amount of damage to the leaves of fruit trees, bushes, vegetables, and a number of other outdoor trees, flowers, and plants. They feast on the tender parts of foliage, and they leave behind a path of destruction.
Every gardener, at one time or another, has had to deal with an infestation of some sort. I myself am something of a gardening novice, but my mother-in-law qualifies as an expert in my opinion. I recently sat down with her and went over various remedies and preventatives.
Japanese beetles are capable of destroying plants and lawns. There are methods you can use to get rid of them.
