Controlling Squash Bugs – How To Get Rid Of Squash Bugs

Squash bugs are one of the most annoying pests that affect your home. They are small, blackish insects with two pairs of wings, which they use to fly around.

Their bodies have a reddish color and their legs and antennae resemble those of a wasp. They are very hardy and adaptable creatures.

They reproduce by laying eggs inside the fruit or vegetable of the plant. When these eggs hatch, they develop into tiny maggots within the flesh of the host plant.

These maggots feed on all organic matter present in the soil surrounding the plant and eventually die out due to lack of food source.

The next stage of life cycle involves the female squashes developing from the egg and then feeding on other hosts. She lays her eggs on various types of plants such as: tomatoes, peppers, lettuce, cucumbers, beans and peas.

Once she has laid her eggs on a certain type of plant, she leaves it to grow until she finds another suitable host.

The best way to control the population of squash bugs is to start early and inspect your plants. You can do this by physically examining the plants in daylight or by using a flashlight at night.

Start with two week old plants and then make sure to carefully examine all of them. If you find eggs, then you should destroy them before they hatch.

You can do this by removing them from the plant. However, if they are on the stem or in the blossom end of the fruit, you will have to remove it from the plant first. You can throw out all infested plants immediately.

Once you have removed all the bugs, stay alert and check your plants often. If you see any eggs that you have missed, be sure to remove them.

Alternatively, you can bring your plants inside before the eggs hatch and keep an eye on them there.

Also, remember to destroy the plant after you have removed all the eggs. If you want to grow that same vegetable or fruit again, you will have to sterilize the soil first.

This can be done using a Clorox solution. Also, you can use a fine mesh screen to cover all drains and openings on your property. This will prevent the adult bugs from getting access inside your property in the first place.

Does Sevin Dust Kill Squash Bugs

I just read that Sevin Dust will kill these buggers.

Does anyone have experience with this?

I live in south Texas, so I’m not sure if it will even work here.

If you only see a few adults and more than half of your plants are still healthy, you can try dusting the leaves of infested plants with Sevin Dust. You can pick up a box at any garden center.

Follow the directions on the package.

This method is not very effective on adult squash bugs, but is more useful for controlling future generations. It takes about a week or so to see results.

The Sevin will kill any eggs or young nymphs that hatch after you dust the leaves, but it won’t kill the adults that are already there. They will just move away and find another plant to live on.

To get rid of the adults, you will have to hand pick them off and squish them. Be sure to get all of the egg laying females too.

Sevin will keep them from producing any more eggs on your plants though.

Getting Rid of Squash Bugs in the Garden

Okay, so my garden is less than 50 feet away from a patch of woods that are filled with wild flowers and vines. I didn’t think this was a problem until a few weeks ago when I started noticing little brown bugs all over my plants.

It took me a day or two to figure out what they were, but once I did I almost cried.

These tiny, practically microscopic, bugs are crawling all over my zucchini plants and munching on my leaves. It’s only been three days and there are so many holes in the leaves that they’re barely recognizable.

I’ve googled everything I can think of to try to figure out what they are and how to get rid of them, but I haven’t had any luck.

I tried an insecticide spray that’s supposed to work on all kinds of bugs, but it didn’t have any effect on them. Next I tried hand picking them off the plants and crushing them, which was actually pretty nauseating since they’re smaller than any insect I’ve ever seen up close before.

After I was done with that I sprinkled a bunch of salt all over the plants and the ground around them. I hope that kills whatever they’re laying their eggs in.

Anyway, if you have any ideas on how to get rid of these things without having to call an exterminator, I would love to hear them. Hope to hear from you soon!

Why hello Lizzie! Getting rid of squash bugs is one of my specialties.

In fact, I just got done writing an entire article about it. You should read it here.

If you’re having problems reading the tiny text on your phone, here’s a quick and dirty version of what you need to do: Spray with soapy water (not dish soap), set out yellow traps, and cover your garden with netting.

Now, since you’ve already tried a couple different methods, I’m going to assume that you’ve already got the soap under your belt. If not, get some Dawn or a generic brand like that and spray it on your plants using a spray bottle you have laying around the house.

It doesn’t have to be expensive, but it has to be soapy.

It’s also time to set out yellowjacket traps. These are little traps that have a sweet substance in them to lure the bugs inside.

You can get these at just about any grocery store, sometimes in the lawn and garden section, sometimes in the pet section. Whichever one you get, just make sure it’s yellowjacket–not honeybee or any other kind of bug.

You’ll most likely have to bait the traps which is also very easy. Just get some fruit juice (or even soda will do in a pinch).

Pour a little bit into the tray of the trap and that’s it. You’re ready to go. Check them every couple days and empty out the trapped bugs (usually stuck in some sort of paper substance at the bottom) and replace the bait.

The final thing you can do is cover your entire garden with mesh netting. You can get a roll of this stuff at a hardware store or sometimes even a big box store like Target or Wal-Mart will have it.

Just make sure it’s the right size mesh so that the adult yellowjackets can’t fly in, but the flying insects still can. This is generally used by people who are growing stuff like berries and flowers to keep birds and other animals out, but it will work for your purposes too.

There you go Lizzie! Three ways to solve your problem.

Hope this helps.

What are those black flying bugs that look like a spider?


I’ve seen a lot of these lately and I’m pretty sure they’re not ants. They don’t look like any type of bug I’ve ever seen before.

They’re small and they have a black “body” with an orange mark on it and they appear to have super long legs. I don’t know if they bite or not but I really hope they don’t because I’m really scared of them.



Hi Beth,

You can stop worrying now because these little guys will not bite people. They are called Lace Wing flies and despite their fearsome appearance they can do no harm at all.

The black and orange coloring is to scare away potential predators. However, they are not effective against humans because we are not likely to eat such a strange looking creature!
