If you ’ve ever grow pumpkin vine , you ’ve plausibly seen squash bugs crawling around in your garden . They ’re one of the most vulgar pesterer for cucurbits . Whether it ’s zucchini , pumpkins , butternut , melon vine , or cuke , mash bugs eff infest squash gardens .
The squash rackets bug looks a lot like a common stinkbug . When I first saw squash bugs on my early pumpkin plants , I adopt they were just stink bugs .
But as the numbers increased , I began to concern . A little research try I had a bigger problem – a squash bug plague on my beautiful , heirloom pumpkins !
What Are Squash Bugs?
Squash bugs ( Anasa tristis)share a lot of characteristic with reek bug . They ’re both gray , heavily - embodied , mallet - type bugs . Many people say that squash bugs also “ stink ” when crushed . But squash bug have a flatter , narrower physical structure , while stink hemipteron look definitely rounded .
Stink bug also prefer to round tomato plant and bean plants , while you ’ll seldom line up squash bugs far from the pumpkin dapple .
The adult crush bug ’s oval torso is rarely over a half - column inch long . But for a little fellow , this pest can cause a heap of damage .
Squash bugs suck out the sap from plant in the cucurbit home : squash , cucumber vine , and melon vine . Adults can also tip on the fruit of these plant – but unless you have an uttermost plague , it ’s rarified to lose healthy plant life to squash bugs .
The Life Cycle of Squash Bug
Adult squash vine hemipterous insect generally winter in or near the garden . They cuddle up under dry out leafage , dead plant life , or other garden clutter until spring warm up the soil . Then , when your cucurbit seedling are springing up in the garden , adult bugs mate and lie down their testis .
Squash bugs unremarkably lay their eggs on the underside of squash leaves . now and again you will find the eggs on top of the leaf as well .
Squash bug eggs are humble , dark , and hard - blast . They look like little brown seed . Squash glitch seeds hatching in about 10 sidereal day , so if you find them , dispatch them right away – before the nymphs come out .
Squash bug houri reckon very like to the adult . They ’re small , gray dirt ball that swarm all over cucurbit . Both grownup and houri squash bugs feed on the leaves and stems of cucurbit plants . But nymphs have a soft organic structure .
By the time you acknowledge squash bugs on your plants , they ’re often adults . While adults are harder to kill , you could manage them when you discover them on your plant life . big squash hemipteran tend to congregate in groups on squash vine and pumpkins .
Because they are n’t solitary creature , it ’s easier to tear them off the plant life and destroy them .
Signs of a Squash Bug Infestation
Of naturally , it ’s easy to roll in the hay that you have a problem when you see bugs on your flora . But that is n’t always a reliable way to figure it out .
When crush bugs assail your plants , they can have a hatful of harm . front for limp leaves , icteric spots that eventually turn brown as the sap is sucked up from within them , and ragged holes in your squash leaves .
These are the clearest signs that you ’ve got a squash racquets bug problem in your garden .
Controlling Squash Bugs
Squash bug control has three stages . If you pass prison term controlling squash microbe early on , you ’ll have fewer bug to dispense with later in the season .
Eggs
Squash bug mate and put down their eggs early in the summer . Expect to find eggs on the underside of cucurbit leaves in early to mid - June . When you see scattered clusters of brown seedlike testicle , scrape them off the leave-taking and into a pail .
I wish to collect all the nut I can happen and then feed them to my wimp , but other gardeners drown them with a little kerosene or oil . you’re able to also use water mixed with dishwashing liquid state .
The point is to get disembarrass of as many testicle as possible before they think up . Once cover , crush bug are a lot more wandering and destructive .
While they ’re fast on the foliage , gather up as many as possible to prevent a mass crosshatch . Most of the time , squash bug ball are on the undersurface of cucurbit leaf , but do n’t be surprised to see them on the top side of leave of absence as well .
Check for eggs on a hebdomadal groundwork throughout former May and early June . Remove egg as you find out them . It ’s potential you ’ll lose a few bunch of testicle , but most of the pests will never see the ignitor of daylight .
Nymphs
Controlling squash hemipteran nymph is a little more challenging than orchis control . Nymphs are mobile . They ’re also thirsty . The nymph devour squash farewell by sucking the succus out . They can also feed on tender , vernal squash and melon vine .
Once squash hemipteran start hatch , walk through the garden with a jar and palpebra . plume the new pestis from their counter and bottle them up .
wimp are less excited about the nymph than they are about the ballock . It may be because of the decidedly malodour - bug flavor of these pests . When I gather squash bug nymphs , I just submerge them in saponaceous piss in a lidded jar . But there are other options .
Many hoi polloi catch both nymph and adult bugs by setting out a wooden board in the garden at night . Squash bugs congregate under the wooden gameboard to savour the residuary heating plant throughout the night .
In the early morning , go out the to garden , and collect the board . Then , you may crush the bug on the board between two severe surface .
Neem oilandhorticultural oilare effective on the houri . If you adjudicate to apply these instinctive insecticides , spray them on the undersurface of the leaves forenoon and evening ( or as the manufacturer recommends ) .
If you employ them systematically , along with other preventive measures , you should be able to vote out off most of the nymphs before they reach adulthood .
Adults
insect powder – both organic and established – are almost completely useless against adult squash bug . Adults are hardy creatures with nerves of brand and a tough exoskeleton .
If you ’ve wait too long to address your crush - bug problem – as I did last yr – then you ’ve got to collect these toughened , quick bugs and overwhelm them in something like kerosene , used motor oil , or water supply mixed with dish soap .
Of of course , you could collect them on a board at dark , just as you did with the nymphs , but adult bugs are a bit harder to smash . Be ready to call for the survivor and try again as soon as you raise up the dining table .
Some nurseryman go through their squash vine with scissor grip each morning and manually cut each louse in one-half . It ’s tedious , disgustful work , but it does reduce the number of bugs in the garden .
If squashing , fade , and drowning are n’t your favorite garden activities ( and they really should n’t be , let ’s be reliable ) – portion out with your squash racquets bugs as early on as potential .
Squash Bug Prevention
After one time of year spent battling squash bugs , I was all set for life . When fall came , I took footstep to make my garden as inhospitable as possible to these invading insects . Fortunately , prevention is similar to many other pest - prevention mensuration .
Step One:
Clean up the garden . place your garden to seam for the winter makes springtime planting prep easier . It also deny winter distance to a host of encroaching bug . Squash bugs drop the inhuman season cover under foliage , dead plants , and detritus .
slay all that fuddle before winter so these insects have nowhere cozy to obliterate during the stale time of year .
Step Two:
exercise crop rotation . Do n’t develop cucurbit family plants in the same spot two years in a row . Move your plant and interchange them with tomatoes or peppercorn . Crop rotation makes sure that when your flock of squash bug wakes up from their long winter naps , they ’ll be farther from the squash rackets plants they get it on .
Step Three:
Plant squash hemipteran - rebarbative familiar plants .
genus Nasturtium , thyme , catnip , and alliums are all naturally repellent to squash bugs . Of course , constitute these companion alongside your squashes wo n’t drive away these pests entirely , but it will promote the pests to look elsewhere for sustenance .
Step Four:
If you ’re not induce a mass of lot keep these insects out of your garden , plant life squash bug - repellent varieties . There are a few cultivars and specie of cucurbit family crops that are resistant toA. tristis .
These plants just do n’t savour honest to squash hemipteran . They have no interest in consume them , so they chop-chop move on to greener gardens .
try out planting ‘ Waltham ’ butternut tree , ‘ Blue Hubbard , ’ ‘ Improved Green Hubbard , ’ ‘ Smooth Criminal ’ summertime squeeze , ‘ Early Summer ’ crookneck , ‘ Royal Acorn , ’ ‘ Long Island Cheese ’ pumpkin , and any butternut tree squelch .
