Grow vegetables at home to keep pests away — just these three essentials, no pesticides needed at all.
Many home gardeners fear pests most. You step out to your balcony in the morning, only to find your leaves chewed up. Some are full of holes, and young seedlings get bitten right off. Your first thought is to spray pesticides. But these vegetables are for your own table, and spraying chemicals just doesn’t feel safe. If you skip sprays, pests multiply quickly.
I struggled with this dilemma for years when growing veggies. Then I figured it out: pest control is not about killing bugs after they arrive. You need to block their access before they come. Stick to these three items, and pests will barely get in.
1.Insect net
This is the most effective method, yet widely overlooked. Many people buy netting only after spotting bugs. But by then, pests are already in the soil. Covering your plants at that point traps the insects inside. They keep feeding and breeding, and the net becomes a shelter for them instead.
Put insect netting in place before sowing seeds or transplanting seedlings. Cover balcony planters, growing boxes, or build small hoop tunnels over your garden beds. Choose mesh with 0.8–1 mm openings. Adult butterflies and moths cannot get through to lay eggs. No eggs mean no caterpillars. Get this step right, and you cut down most of your pest worries.
For my cabbages and radishes, I cover them right before sprouts emerge. No sprays all autumn, and the leaves stay clean.
2. Yellow or Blue Sticky Traps
Insect netting blocks adult pests coming from outside. But there may already be eggs in the soil, or you might bring pests in when tending your garden — netting cannot stop those. That’s where yellow and blue sticky boards work.
Aphids and whiteflies are drawn to yellow. Thrips prefer blue. Stick a few traps beside your pots. The tiny flying bugs will land on them. Place the traps 10–20 cm above the top of your plants. Too low and they catch nothing; too high doesn’t work either. One or two traps per 10 square meters is sufficient.
No mixing chemicals, no spraying. Just insert them. Replace once they are covered with bugs. Super easy.
3 Remove plant debris after harvest
This method costs nothing, yet it’s the most ignored.
After harvesting a crop, many gardeners leave old, rotten leaves and dead stems lying on the soil or pile them beside the garden. It feels like extra work, not worth the trouble. But these leftovers hide insect eggs and larvae. They overwinter there, and hatch again when temperatures rise the next year to ruin your new crops. If pests come back every season, leftover debris is usually the reason.
Once you finish harvesting, clear away all yellowed foliage, weeds and dead plant matter. Do not pile it near your growing area; dispose of it far away. If you reuse the soil, spread it out under direct sunlight for 3–5 days in summer. Strong sunlight kills many eggs and pathogens.
That’s all three steps. Cover early with insect netting, hang sticky traps, and clean up after harvest. Pests won’t get out of hand without pesticides.
You may ask: what if pests have already appeared?
For just a few bugs, pick them off by hand. For heavy aphid infestations, spray soapy water: add 2 drops of dish soap to 1 liter of water. Spray every three days, repeat three times. If cabbage caterpillars spread, use Bacillus thuringiensis (Bt), mixed with water following package instructions. These are emergency treatments only, not for daily use.
Stick to the three core methods daily: insect net cover, sticky traps, and post-harvest cleanup. Pest pressure will drop drastically.
I have never bought insecticides in all my years of home gardening. Relying on these three tricks, my vegetables grow well. A few small holes are no big deal — just wash the veggies and enjoy your harvest.

How to Maintain Greenhouse Structures After Construction in the Age of Progress?
As times advance and things evolve, an increasing number of farmers are entering the vegetable cultivation industry. Greenhouses in Guizhou are becoming more active. So, how should greenhouses be maintained after construction? Here are a few key points summarized for your reference:
1. Over time, loose soil may cause the greenhouse structure to tilt. If this occurs, promptly realign the frame to prevent further damage.
2. Minimize human activities such as climbing on the greenhouse, which can add unnecessary stress. Newly built vegetable greenhouses, especially when overloaded, may not withstand strong winds or rain, leading to cracks, breakage, or even collapse of the frame.
3. Rainwater erosion can create gaps and hollows at the base of the greenhouse. Once noticed, immediately compact the foundation to ensure stability.
4. During use, greenhouse films are most vulnerable to damage. Always handle them with care—avoid using sharp objects that could puncture or tear the film.

Application Effects and Techniques of Insect Net in Protected Vegetable Cultivation
2026-08-12
The insect-proof net is a new type of covering material manufactured by drawing and weaving polyethylene (PE). It looks similar to window screen. It boasts high tensile strength, UV resistance, heat resistance, water resistance, corrosion resistance and anti-aging properties. Non-toxic and odorless, it has a service life of 4 to 6 years. It retains the merits of shade nets while overcoming their drawbacks, making it worthy of extensive promotion.
1. Covering Methods and Effects
Insect-proof nets are mainly used to cover small and medium-sized tunnels. Full-cycle continuous covering is recommended. Its main effects are as follows:
(1) Pest Prevention
Summer and autumn witness frequent outbreaks of pests such as imported cabbageworms, diamondback moths, Spodoptera litura, cabbage moths and beet armyworms. After covering with insect-proof nets, the fine mesh and year-round coverage block adult pests from flying or crawling into the growing area, forming an artificial barrier in the field to effectively prevent pest invasion. Nets of 20–30 mesh can prevent damage from major pests inside greenhouses, including leafminers, aphids, flea beetles, imported cabbageworms and diamondback moths, achieving excellent pest control results.
(2) Prevention of Viral Diseases
Vegetable viral diseases are generally transmitted by aphids, planthoppers, whiteflies and other pests. By blocking these pests, insect-proof nets cut off transmission routes of viral diseases and reduce their incidence in vegetables.
(3) Reduction of Pesticide Consumption
Without insect-proof nets, vegetable production relies heavily on insecticides, especially in summer and autumn. Frequent pest outbreaks increase cultivation difficulty, leading to frequent and heavy application of chemical pesticides. With insect-proof net covering, pest populations drop sharply or pests fail to appear. This greatly cuts insecticide usage. In some cases, no insecticides are needed throughout the growing season, and vegetable quality is improved accordingly.
(4) Resistance against Typhoons, Heavy Rains and Hail
In summer, strong winds, heavy rains and hail cause mechanical injuries to vegetables, resulting in lodging and seedling death. Thanks to the fine mesh and high mechanical strength of insect-proof nets, they perform remarkably well against heavy rain erosion. During the plum rain season, concentrated heavy rainfall often causes severe losses or total crop failure for leafy vegetables. When covered by insect-proof nets, raindrops strike the net and turn into fine drizzle with greatly reduced impact force, which facilitates vegetable growth and development. In addition, insect-proof nets can withstand strong winds and hail.
