There are two reasons:
Insecticides do not last forever.
Insecticides are classified as either residual or non-residual. Basically this refers to how long the insecticide lasts on the surface it comes to contact with.
For instance, a residual insecticide might be long-lasting and thus, may stay on the surface for months. However, a non-residual insecticide may only be effective for a day or a week.
Resistance.
Insects normally have very high and rapid reproductive rates. This means that if for some reason a very small percent of the insect population has an inherent resistance to the particular insecticide that genetic trait is quickly passed to subsequent generations - making the insect resistant to the use of that particular pesticide.

Beauveria bassiana is a common fungal insecticide used to control a variety of insect pests. It infects insects by attaching to their cuticle and penetrating their body, ultimately causing death. Beauveria bassiana is considered an environmentally friendly alternative to traditional chemical insecticides.
Yes, carnivorous plants can help control insect pests by trapping and consuming them. They are a natural form of pest control that can be used in certain environments to reduce insect populations. However, they may not be as effective in controlling large pest populations or in commercial agricultural settings.
Alternatives to DDT for pest control include integrated pest management (IPM) strategies, which focus on combining biological, cultural, and mechanical control methods to minimize pest populations. Other chemical alternatives include insecticides such as pyrethroids, neonicotinoids, and insect growth regulators, which target specific pests while being less harmful to the environment. Additionally, organic options like neem oil and diatomaceous earth are used in sustainable agriculture to manage pests without the risks associated with DDT.
Hamsters are not considered pests. They are domesticated rodents that are commonly kept as pets due to their small size, ease of care, and cute appearance. In the wild, hamsters play a role in their ecosystems, such as helping to control insect populations.

Companion plants, crop rotation, herbicides, insecticides, natural enemies, plowing and tilling, resistant varieties, row covers, and soil drenches are ways that farmers control the growth of insect pests. Insect pests can shelter in weeds, whose presence can be eliminated by pre-emergent, target-specific herbicides that eliminate undesirable vegetation before they can take over resources and space and by soil drenches that eliminate ground-dwelling, surface-sheltering insect pests. Companion planting, crop rotation, natural enemies, resistant varieties, and row covers number among the more natural, non-synthetic, organic ways to control the growth and return of insect pests.

Yes, permethrin is generally considered safe for use in controlling pests and protecting against insect bites when used according to the manufacturer's instructions. It is commonly used in insect repellents and insecticides for clothing and gear.

Habitat reconfiguration, manual removal, mechanical barriers, natural enemies, and target insecticides are ways to get rid of insect pests. Insect pests come to places which offer food and shelter, both of which functions therefore need to be disabled or minimized. They may be removed by perishing thanks to biological predators, picking or swatting into water-filled buckets for drowning, shunning through row covers, and terminated with insecticides whose active ingredients are environmentally non-damaging but target-specific.
