How do I get rid of squash bug?
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 heard there is an organism in garden soil that can be harmful to pregnant women. Is this true?
- I have two Espalier apple trees and I would like to know when is the best time to prune them and should they produce every year or do they only produce by cycle's (every so many years)?
- When and with what should I spray my peach and apple trees for pests?
- Moved to a new location in Riverton and started a garden. This spring I added compost and steer manure. The garden is watered using secondary irrigation. The leaves on the beans, corn, and strawberries turn yellow with a burned look on the outer edges of the leaves and then the plant dies. The tomatoes and melon plants all seem to be doing well. Any idea's?
- I have heard that black walnut sawdust should not be used in composting. People have told me it is poisonous to other plants. Is that true. I have several bushels of sawdust and would hate to send it to the land fill, but don't want to poison my garden either.
- I have 4 lovely crenshaw melons on my home garden vines -- 1 large, 2 medium, and 1 small. None of them have gone yellow/white yet! We survived the snow flakes last weekend (I covered everything), but I see we are about to get another "hit" this weekend! Is there ANYthing I can do to speed up their ripening?? I have cut back my watering of the vines, but sprinklers still go on automatically in the morning. Would any of the "usual" things people do to ripen melons indoors (paper bags, put them with a banana, etc.) do any good while they are still on the vine?? From everything I have read, if they are picked while they are still green, they will never ripen -- is this true? If I keep them well covered during our few nights of 32-33 due this weekend, will they survive on the vine to ripen?
- 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.
- When should apple trees be sprayed and how should we go about it. Is there someone in Utah Co. who will come and do it. We have a golden apple tree that produces big, good apples when taken care of.
