What do I do about squash bugs?
Rate This FAQ
Squash bugs are very difficult to control. Insecticides are not very effective, but if insecticides are used they work best against the very young nymphs.
* If you plan to use insecticides, sprays should be applied when small nymphs are present, which generally occurs early in the season.
* Before spraying, check plants carefully to make certain that small nymphs are present. Squash bugs hide on the underside of leaves or down near the base of the plant.
* Nonchemical methods of control are usually as effective as insecticides. Serious attack by squash bugs can be avoided by planting sensitive varieties early so harvest is complete by early August.
* Once harvest is complete, remove the squash plants from garden. Plants left in the garden allow the bugs to build up to higher numbers, which will lead to greater problems the following year.
* Plant varieties of squash that are less sensitive to the bugs. Zucchini seems to be the variety most sensitive to attack by squash bugs. Other summer varieties and most winter varieties seem better able to tolerate feeding by squash bugs.
* Squash bugs are active during the day. At night the bugs hide under boards or other objects. This behavior can be used against them in small scale plantings such as gardens. Place boards near the plants (between rows or around the garden edge) and early every morning turn them over and squish all the bugs you find.
* Squash bugs also seek out sites like wood piles or sheds to spend the winter. Large numbers of bugs overwintering in these sites can lead to high numbers of bugs in your garden the following year.

- I planted tomatoes last weekend because it looked like we were going to have warm weather, but yikes! it says it will snow tonight. How can I protect my little tomato plants?
- I am wrapping up my garden for the year. I have been looking at adding horse manure to my garden soil to boost the organic matter in it. This year I added NutriMulch (turkey manure blend) and that worked out well, but was expensive. I'm concerned about the soil quality. I notice that it's pretty hard when in big dry clods. Would I be hurting my garden to add green horse manure now, and tilling it in? I've read a little about deficiencies in the soil because of too much horse manure, so if it's safe or even a good idea to add to a garden, how much is the right amount?

- I have some shrubs that have been dying off in a wierd manner. Just sections at a time will completly die in a matter of a day or so, not even time to try and treat it. There are no outward signs of bugs and the rest of the shrub will be perfectly healthy. It has done this to more than one of my shrubs and also done this to more than one kind of shrub. It started last summer where I lost part of a couple and one hole shrub. I thought I had it taken care of by the end of the summer but when I mowed last week for the first time I noticed I have almost totaly lost another and there are spots on some others. The plants have been here for as many as 10 years or so and are very well taken care of. The only thing I can think of is about 3 years ago I put new plastic down and new bark, could the new plastic cause this.
